Impulse control increased by dopamine replacement in early Parkinson's

New Penn Medicine research shows that neuropsychiatric symptoms such as depressionanxiety and fatigueare more common in newly diagnosed Parkinson's disease (PD) patients compared to the general population. The study also found that initiation of dopamine replacement therapy, the most common treatment for PD, was associated with increasing frequency of impulse control disorders and excessive daytime sleepiness. The new findings, the first longitudinal study to come out of the Parkinson's Progression Markers Initiative (PPMI), are published in the journal Neurology®, the medical journal of the American Academy of Neurology.
The PPMI, a landmark, multicenter observational clinical study sponsored by The Michael J. Fox Foundation for Parkinson's Research, uses a combination of advanced imaging, biologics sampling and behavioral assessments to identify biomarkers of Parkinson's disease progression. The Penn study, which represents neuropsychiatric and cognitive data from baseline through the first 24 months of follow up, was conducted in collaboration with the Philadelphia VA Medical Center and the University Hospital Donostia in Spain.
The study examined 423 newly diagnosed, untreated Parkinson's patients and 196 healthy controls at baseline and 281 people with PD at six months. Of these, 261 PD patients and 145 healthy controls were evaluated at 12 months, and 96 PD patients and 83 healthy controls evaluated at 24 months.
PD patients were permitted to begin dopamine therapy at any point after their baseline evaluation.
"We hypothesized that neuropsychiatric symptoms would be common and stable in severity soon after diagnosis and that the initiation of dopamine replacement therapy would modify their natural progression in some way," says senior author, Daniel Weintraub, MD, associate professor of Psychiatry and Neurology at the Perelman School of Medicine at the University of Pennsylvania and a fellow in Penn's Institute on Aging.
The Penn team showed that while there was no significant difference between PD patients and healthy controls in the frequency of impulse control disorders, a neuropsychiatric symptom that can lead to compulsive gambling, sexual behavior, eating or spending, 21 percent of newly diagnosed PD patients screened positive for such symptoms at baseline. That percentage did not increase significantly over the 24-month period.
However, six patients who had been on dopamine therapy for more than a year at the 24-month evaluation showed impulse control disorders or related behavior symptoms while no impulse control incident symptoms were reported in PD patients who had not commenced dopamine therapy. Dopamine therapy did help with fatigue, with 33 percent of patients improving their fatigue test score over 24 months compared with only 11 percent of patients not on dopamine therapy.
The investigators also found evidence that depression may be undertreated in early PD patients: Two-thirds of patients who screened positive for depression at any time point were not taking an antidepressant.
PPMI follows volunteers for five years, so investigators plan to expand upon these results, which Weintraub still considers preliminary. "We will more closely look at cognitive changes over time," he says. "Two years is not a sufficient period of follow up to really look at meaningful cognitive decline."
The perspective of time is what makes the PPMI such an important initiative, Weintraub points out, since many patients with the disease live for 10 to 20 years following their diagnosis. "It's really a chance to assess the frequency and characteristics of psychiatric and cognitive symptoms in PD, compare it with healthy controls, and then also look at its evolution over time," he says. "The hope is that we will be able to continue this work so that we can obtain long-term follow up data on these patients," says Weintraub.

Dental Implications of Parkinson’s Disease


Satbir Grover, B.D.S., M.S., and Nelson L. Rhodus, D.M.D., M.P.H.:

At the turn of the new century, while the world — and media around the globe — were worrying about the “Y2K” threat to its computers, a more significant phenomenon  crept into the background with hardly a headline: the dawn of “the age of the aged”. This fastest growing segment of our society, also referred to as the “Aging Tsunami”, is  over the age of 65 and consists of 14% of the U.S. population today. As shown by the latest estimates, people over 65 years of age will make up to 23% of the U.S.  population, or approximately 68 million people, by the year 2050, and people aged 85 years or more will also increase three-fold, thus making this the fastest growing segment  of U.S. society.1 This wave of retirees, known as the Baby Boomers, will also be associated with an increasing number of medical conditions having a major impact on the health care system of the nation. One of the most common chronic diseases associated with old age is Parkinson’s disease (PD), which demands a customized interdisciplinary  approach, with medical and dental specialties working together for the optimal treatment of the patient. 

Parkinson’s patient being tested by physical manipulation. Dental practices will be seeing an increasing number of PD cases.

Background
Parkinson’s disease, or Paralysis agitans, is a progressive, neurodegenerative disorder that affects movement, muscle control, and balance, as well as numerous other non- motor functions. It is part of a group of conditions known as Motor Systems disorders. Also known as the “shaking palsy”, the disease was named for James Parkinson, a  general practitioner in London during the 19th century who first described the symptoms of the disease. Symptoms describing Parkinson’s disease are mentioned in writings on  medicine in India dating back to 5,000 B.C., as well as in Chinese writings dating back approximately 2,500 years. Parkinson’s disease is the most common movement disorder  and the second most common neurodegenerative disorder, the most common being Alzheimer’s disease. 

Epidemiology
According to the National Institute of Neurological Disorders and Stroke (NINDS) (http://www.ninds.nih.gov), there are approximately 1.5 million people in the U.S. who suffer  from Parkinson’s disease — approximately 1-2% of people over the age of 60, and 3-5% of the population over age 85. Various studies have reported the incidence of PD  from 8.6-19 per 100,000 people. Approximately 50,000 new cases are diagnosed in the U.S. annually. This number is expected to rise as the general population in the U.S.  ages. A typical dental practice could expect approximately four to five patients with PD every day. 

Onset of Parkinson’s disease before the age of 40 is still rare. However, all races and ethnic groups are susceptible and can be affected. Some of the studies suggest an  equal distribution of PD among males and females before the age of 60, but higher in males past 60 years of age. More information can be collected from the American Parkinson’s Disease Association (http://www.apdaparkinson.org). 

Pathophysiology
Parkinson’s disease occurs when there is a disruption of the neurotransmitters or dopamine production which leads to impaired communication between brain cells in the basal  ganglia. The reduced level of dopamine causes the nerve cells to fire out of control and causes a loss of smooth, controlled muscle activity. Also, death of dopamine-producing cells in the substantia nigra eventually results in a reduced level of dopamine in the corpus striatum, which is considered to be the primary pathology in Parkinson’s  disease.

By the time symptoms develop, there is at least 60% loss of dopamine-producing cells in the substantia nigra and an 80-90% loss of dopamine in the corpus striatum. 

Increasing evidence suggests that Parkinson’s disease is a multisystem brain disease in which various neurotransmitter systems are affected, and related deficits become  more prominent over the course of the disease. In addition, it is known that the disease process of PD begins long before motor symptoms are clinically visible. Many patients  report that they have already experienced non-motor symptoms associated with PD such as fatigue, constipation, and olfactory changes several years before clinical onset.

Parkinson’s disease is also characterized by the presence of Lewy bodies, structures that are found in the cells of the substantia nigra as well as in other secondary  locations. Lewy bodies are strongly correlated with neurodegeneration and are considered a diagnostic hallmark of Parkinson’s disease.2 

Etiology
There is convincing evidence that the Parkinson’s disease neurodegenerative process begins many years before the onset of motor manifestations. Initial estimates based on  nigral neuropathological findings or striatal dopamine imaging suggested a five-to six-year preclinical period. However, more recent evidence of Lewy body pathology in other  neuronal populations preceding nigral involvement suggests that the preclinical phase may be much longer.3 

According to the Parkinson’s Disease Foundation, two major factors are considered the cause for Parkinson’s disease: genetics and environment. 

Genetic Factors
Based upon the current research, the vast majority of Parkinson’s cases are not directly inherited, as about 15 to 25 percent of people with Parkinson’s report having a relative with the disease. In large population studies, researchers have found that, as compared to the general population, people with first degree relatives such as parents  or siblings suffering from PD have a four to nine percent greater chance of developing PD. Scientists have discovered mutations in genes that play a role in dopamine cell functions. These genes include alphasynuclein, leucine rich repeat kinase 2 (LRRK-2), and glucocerebrosidase (GBA).4 While it is possible these mutations may be the cause  for the disease directly, they seem to affect only a small number of families. 

Environmental
Some studies have demonstrated that prolonged occupational exposure to certain chemicals is associated with an elevated risk of PD. Epidemiological research has identified  several factors that may be linked to Parkinson’s, including rural living, well water, manganese, and pesticides. In 2009, the U.S. Department of Veterans Affairs added  Parkinson’s to a list of diseases possibly associated with exposure to Agent Orange. 

A synthetic neurotoxin agent discovered in the 1980s called MPTP can also cause immediate and permanent Parkinsonism. The compound was found mainly in individuals who  injected themselves with a synthetic form of heroin contaminated with MPTP. However, cases of MPTP-induced Parkinson’s in the general population are exceedingly rare.

Recent evidence indicates some other contributing factors which when integrated with the major cause may lead to a high PD rate. They are: 
• Oxidative damage: Some researchers consider free radicals or even endogenous toxins circulating in the body to be a contributing factor in PD.5 
• Toxins: Chronic exposure to toxins such as pesticides, considering the geologic location and living conditions of the patient, can lead to considerable loss or degeneration of the dopamine-producing cells. 
• Occupational hazards: A high prevalence of PD is thought to be present in patients related to occupational fields such as welding, cleaning, or farming. Even drinking water  from wells with high concentrations of heavy metals like mercury, iron, zinc, manganese, and so on for an extended period of time may increase the incidence for PD.6 
• Aging: The latest evidence indicates the normal aging process is a natural cause in reduced or even accelerated death of dopamine-producing cells in PD patients.7 

Scientists have proposed that clinical, neuroimaging, and pathologic examination of the patients having a variety of non-motor symptoms known as the “premotor phase” can precede the classic motor features of Parkinson’s disease by years and, perhaps, even decades.8 

Signs and Symptoms
The four primary motor symptoms considered the hallmark of PD are also known by the acronym T.R.A.P: tremor (resting tremor); rigidity (muscle rigidity); akinesia and bradykinesia; and postural instability.9 

Tremors
Tremors in patients with PD can be unilateral or bilateral, most commonly noticed as a “pill-rolling” movement of the thumb and the opposing fingers. Resting tremors which disappear with the motion of the hand are present in approximately 70-80% of the diagnosed cases. This symptom worsens with climatic changes, especially winters, and  with anxiety, excitement, or even apprehension. 

Rigidity
Rigidity consists of increased tone or stiffness of muscles. It may be not reported in initial cases of PD. However, it may be noticeable upon physical manipulation by the physician. One can also appreciate smooth muscle movements replaced with a broken-up ratchet type of action commonly known as “cogwheel rigidity”, manifesting as reduced swinging of arms with foot dragging while walking. 

Akinesia and Bradykinesia
Akinesia refers to significant reduction or absence of spontaneous movement, whereas bradykinesia refers to slowness of movement. PD patients commonly report akinesia to  be most distressing, as it makes small tasks time consuming, such as the delay in initiation of the movement required for walking. Bradykinesia can also be frustrating, as it  interferes with basic activities such as dressing, household chores, or even sitting down and getting up from a dental chair. It may also manifest as reduced facial expression,  commonly known as “mask face”. 

Postural Instability
Gait changes include asymmetric slowness, reduced arm-swinging, and stooped posture, shuffling, and often leaning forward or backward, leading to a high number of cases  of falls in patients with PD. 

Other medical symptoms associated with PD can vary from “festination” or “freezing” to sudden inability to initiate movement through a spectrum of non-motor complications10 such as cognitive impairment, dementia/other psychotic symptoms, depression/mood fluctuations, fatigue/pain, shortness of breath, visual disturbances, or  sexual dysfunction. 

Differential Diagnosis
Numerous medical conditions can mimic the symptoms of Parkinson’s disease. They can be divided into three major categories: medicationinduced Parkinsonism, Parkinson-plus   syndrome, and essential tremors. Parkinson’s-disease-like symptoms can be secondary to some other underlying conditions or medications such as antipsychotics,  antiemetics, antihypertensives, antianginals, or antineoplastics. Because no diagnostic tests can clearly detect PD, the diagnosis requires extensive details regarding the  history of the symptoms, clinical examination of the patient, and specific tests or images to rule out the other mimicking diseases such as multi-infarct disease or multiple small strokes (vascular Parkinsonism), Huntington’s disease, Lewy body dementia, progressive supranuclear palsy (PSP), or Wilson’s disease.11 

Oral Manifestations
In the famous words of Louis Pasteur, “In the fields of observation, the favorites do prefer the prepared minds.” 

Systemic health is often related to oral health. Many systemic diseases are manifested in the oral cavity. In addition, some of the therapies used to treat them have effects  on the teeth and mouth. Patients with Parkinson’s disease display a number of oro-facial manifestations. As discussed earlier, these manifestations are secondary to motor  and sensory deficits. They can display in a range of symptoms such as the following. 

Dysphagia. With PD, even normal swallowing of food or water can be a challenge. This affects up to 75% of PD patients, and even the normal swallowing of saliva is affected. With the progression of disease, the greatest risk, that of “silent aspiration”, also increases. It leads to aspiration of small amounts of food or saliva without normal  protective reflexive mechanisms, and thus a high prevalence of pneumonia is reported in patients with PD.12 As well, the tongue does not depress sufficiently to allow food to  proceed to the throat. 

Salivary dysfunction. In PD patients, the normal salivary function is disrupted and can result in either varying degrees of reduced saliva production or xerostomia. It can also swing in the opposing direction of excess saliva production, or sialorrhea. As a consequence, the normal salivary functions such as lubrication, solubilizing foods, assisting  chewing and swallowing, and providing stability to the normal buffer system to protect teeth is disrupted. Parkinson’s disease is often associated with excess saliva, drooling,  and difficult swallowing.13 Up to 78% of PD patients report sialorrhea, which manifests as drooling with a high incidence of fungal infection (angular cheilitis) at the corners of  mouth. On the other hand, reduced salivary secretion leading to xerostomia, or dry mouth, is a significant factor aggravating the rate of dental decay, especially roots  caries.14 Xerostomia may result from the disease process, or from a complex of factors such as treatment of PD, drug therapy side effects, and generalized decrease in saliva  associated with aging. In Parkinson’s disease, dry mouth is frequently the side effect of taking anticholinergic medications. It has been found that patients with dry mouth are  not only more prone to cavities, but may have tooth sensitivity.  Additionally, the tissues in the mouth may become dry and at times painful. 

Burning Mouth.
Burning mouth is fairly common in PD patients, compounded by xerostomia, medications, nutritional deficiencies, and even poor oral hygiene resulting from reduced muscle co-ordination required to grip a normal toothbrush. 

Changes in taste and smell.
Patients with PD are more vulnerable to changes in their taste and olfactory functions. Altered salivary functions and medications are considered to play a major role for the  same. Muscles in the GI tract can be also be affected by PD, resulting in a feeling of food chunks “sticking” either in the throat or stomach and leading to heartburn or  gastroesophageal reflux disease (GERD). Thus PD patients may complain of reduced flavor from food or, often, a bad taste in the mouth. 

Other symptoms commonly associated with PD are: Speech impairment. Soft voice, slurred words, fast speech, or hesitation before speaking are often and commonly  encountered. Difficulty in understanding the patient may result in reduced appreciation and reporting of pain or discomfort by the dental provider. It may be the first non- motor symptom that can indicate possible PD. 

Bowel dysfunction.
Bowel dysfunction — i.e., reduced control over bowel and bladder in patients with Parkinson’s disease — can lead to embarrassment, social isolation, and even admission to  long-term care.15 The condition will have to be considered by and for the entire dental team while making extensive treatment plans such as multiple crowns or implants which require extended chair time, as the procedure may need to be stopped to allow frequent restroom trips by the patient. 

Orthostatic hypotension.
Orthostatic hypotension is frequently encountered in Parkinson’s disease, and its diagnosis remains manometric (a fall of at least 20 and/or 10 mmHg in standing blood  pressure).16 This is of special consideration when planning a dental procedure where the patient will be in a supine position for a long period of time. Orthostatic hypotension  can also be a secondary effect of anti-hypertensive drugs. 

Fatigue.
Physical and mental fatigue is one of the most common complaints of Parkinson’s disease patients, and is often associated with reduced activity and poorer quality of life.17  It ranges from a patient complaining of being tired or feeling uneasy in the middle of treatment to frequent requests to stop the procedure before it has been completed. 

Anxiety.
Anxiety disorders are common in Parkinson’s disease patients. As the latest research indicates, anxiety disorders decreased with age, and young onset PD patients were more  likely to experience anxiety than the late onset subjects.  Anxiety adds to the complexity of PD, thus lowering patients’ quality of life.18 Incidences of patients with mood swings are common, and cases of compulsive behaviors are also reported. However, this is of very low degree. It may be of concern when considering the safety not only of  the patient but of the dentist and staff. 

Dental Management
Parkinson’s disease is a chronic, progressive condition that is associated with increasing disability in areas such as motor function, balance, mood condition, behavior,  activities of daily living, and overall quality of life. Patients with varying degrees of dyskinesia of the hands or/and face are often associated with poor oral hygiene and  infections of the gums and periodontal tissue. Studies have indicated that patients with a diagnosis of PD may have poorer oral hygiene and a greater incidence of infection  as compared to the general public.19 

Taking a detailed medical history before the commencement of any dental treatment is the best approach to complete patient care. The dentist should concentrate on the overall medical health of the patient; information regarding the patient’s medical diagnosis; and maintaining a complete list of medications, whether present or discontinued. A  history of any surgeries should be collected in the initial visit to the dental clinic. 

Conducting medical history reviews and measuring a patient’s vital signs, including blood pressure, heart rate, pulse, and respiratory rate on every visit should be standard practice and performed primarily by the dentist.24 This model always helps guide the dentist in identifying benefits and risks associated with the patient and planning for  treatment.  Contraindications associated with any concerning medical condition can be determined in these initial stages, and the dentist can refer the patient to his or her  primary physician for consultation. Information regarding the medical condition, cognitive status, disease prognosis, drug regimens, and even modifications that need to be  done during the dental procedure can be discussed.20 The major challenge for patients with PD is adapting to their progressive disability. The dentist should devise a realistic  treatment plan considering the current status of the patient and the degree of dental treatment required. The restorative procedures should be completed in initial stages of the disease, taking into account the reduced ability of the patient to tolerate longer appointments, or even reduced cooperation as the disease progresses. The dentist  should be able to discuss an immediate versus long term treatment plan either with the patient or his family/responsible party so as to prevent future complications.   

The degree of muscle rigidity can be a challenging factor in the maintenance of oral hygiene. Studies indicate that PD patients had more complaints about their oral health  and more problems in oral health behavior than did the general population.19 The dental treatment should always begin with the identification and diagnosis of the disease, its  associated risk factors, and discussion between the dentist and the patient or his family members. The dentist plays an integral role in providing complete health care to an  individual. The patient should be educated and continuously motivated for the maintenance of good oral hygiene. The role of basic hygiene aids such as toothbrush, tooth  paste, and even floss should be explained in detail. The dentist or hygienist can help the patient in modifying the oral hygiene techniques considering the degree and  progression of the disease. The importance of good oral hygiene should be reinforced by the fact that it can help reduce complications associated with many systemic  conditions such as diabetes. Improvements in oral hygiene may reduce the risk of developing infective endocarditis (IE)21 and also reduce the incidences of aspiration of  microorganisms leading to aspiration pneumonia.22  With the progressing tremors and poor muscle coordination, patients may face concerns with their grip and therefore  overall dexterity to clean the teeth. This can range from reduced grip over the toothbrush to squeezing toothpaste out of the tube. The toothbrushes with the wider grip can  be more handy for patients with PD. The brush can be fixed inside the bike handlebar grips or the tennis balls so as to increase its surface area, thus making it comfortable to  grip and use by the patients. The newly available power toothbrushes have proven to be a boon to these patients. They come with a thicker handle, improving the grip  substantially. The improved versions have a timer with an On/Off switch, keeping the patient on track for the proper brushing for the suggested length of time. Toothbrushes  with soft bristles and smaller heads so as to reach all the corners of mouth should be preferred. The toothbrushes should be replaced after every three months or when the  bristles start showing indications of fanning out. Toothpaste pumps are available to dispense a fixed amount of toothpaste as required. The patient should also be motivated for the regular use of dental floss to improve oral tissue condition and reduce plaque build-up. Waxed or non-waxed dental floss is available for the patient’s choice, with floss holders and interproximal brushes to aid in better cleaning. If the patient is partially or fully edentulous, and uses partial, fixed, or complete dentures, emphasis should be  placed for the regular cleansing of the dentures. 

With the growing demand for dental aids, mouthwashes have developed to suit the individual. Patients with PD can be informed about various mouthwashes available.23 Emphasis should be placed on the use of non-alcoholic, fluoridated mouth rinses to improve overall benefit with other hygiene aids. Based on current studies, a combination of  fluoridated toothpaste and anti-microbial mouth rinses such as chlorhexedine is a useful, simple, quick, and non-invasive method for the control and management of existing  root caries lesions. Simultaneously, the patient should be informed regarding the proper method for the use of mouthwash, as spitting it out can be a challenge with the  progression of the disease. Patients with reduced oral muscle control can be trained to either dip their brushes in the mouthwashes before brushing or to bend down over the  sink and rinse, as gravity will allow the mouthwash to flow down the sink, thus reducing the incidence of uncontrolled swallowing by the patient. 

Patients having memory issues and difficulty remembering details about brushing or flossing can post sticky notes at the brushing area to remind them to follow the steps  every day. Family members or caretakers can remind patients to brush and floss as well. For complete oral hygiene, the tongue should be thoroughly cleaned, as it can be a  trap for food particles, particularly with PD-related xerostomia. 




 

Conclusion
Maintenance of the oral health of patients with Parkinson’s disease should be of prime importance in providing complete health care to this fastest growing segment of our  society. Dentists who are well informed about the manifestations of PD, with its direct and indirect effects on oral health, will be in a better position to provide complete dental  care to patients suffering from this disease.

The Emotional Impact of Parkinson

By Nessa Weinman

Take a deep breath in, hold, and let it out. Simple exercises and talking with others can help with the intense emotional feelings such as depression. anger. fear and isolation from friends and family. Now take in another deep breath in, hold and let it out with a big sigh. These are just some feelings that may come with news of a Parkinson’s Disease diagnosis or even many year’s after. It’s not unusual for patients to deny their diagnosis, often missing medical visits, refusing to take medications, and even withholding information from family members.

These are very normal human reactions that express the fear of being ill, and the hope that a diagnosis was incorrect. 

The emotional and psychological impact of Parkinson’s on the patient, family, and caregiver, is profound. This article will take an in-depth look at the emotional impact of the disease and identify therapies that have been proven to be effective. Everybody is different so  there are a range of therapies and with some practice, you will find what works best for you.

The transition from full health to the limitations that come with illness is a difficult journey. Our self-image is altered, and we are likely to question our value to ourselves and others. Nobody wants a neuro-degenerative disease, but there are many treatments available and researchers everywhere are working hard to find even better treatments and a cure.
With good tools, hard work and talking to others, these emotions eventually subside. Deep breath, hold, and let it out slowly. Confronting a new reality takes time and with proper help and guidance, you can begin to make changes that will enhance your ability to live with Parkinson’s and still have a good quality of life.

Let's begin with some basic details about PD and how it manifests as an emotional issue.

The Patient and the Emotions of PD

Parkinson’s Disease, at this moment in time, has no cure, and most patients grow progressively worse over time. Receiving a PD diagnosis, or learning that a beloved family member has it, often triggers an immediate reaction of sadness, or sorrow, in addition to helplessness and even anger.
Some of these emotions may result from the disease itself, rather than an emotional reaction to the news of a PD diagnosis.

More than 60 percent of people with Parkinson’s experience depression.  In fact, you may have experienced it as one of the first symptoms of Parkinson’s, long before you were diagnosed.” (Parkinson’s Association 2014). http://www.parkinsonsassociation.org/about-parkinsons-disease/depression

Emotional distress, whatever the cause, can begin a sort of chain reaction, or spiral effect. For example, a patient showing initial signs of PD is diagnosed with the condition. In the next few weeks sleep disorders appear. Cognition seems slow and fuzzy; concentration declines, and apathy increases.
What this illustrates is that any treatment for PD must include the family. It is too easy to misinterpret emotional symptoms as physical manifestations of the disease.

Working two fronts

There are effective interventions and treatments for PD, and it is imperative that a patient and their family or caregivers realize that any approach must have two "fronts". It must strive to address the actual progression of the disease, as well as the emotional and mental impact it has on everyone involved.
Let’s take take a look at a list of indicators and symptoms of the emotional toll of PD:
·         Depression - According to the Michael J. Fox Foundation "at least half of all Parkinson’s patients suffer from clinical depression at some point."
·         Anxiety - The intensity of PD forces many patients to worry about issues far outside of their control. This leads to anxiety. Patients worry about being a burden, about taking falls or being unable to move, they worry about loss of memory, and so much more.
·         Apathy - PD is often accompanied by a seeming sense of apathy, making it appear that the patient does not care or is indifferent about many things. Often this is a very serious misunderstanding on the part of the family or caregiver as the appearance of “laziness” is often due to the impact of the disease and not a controlled response.
·         Insomnia - Many patients find sleep very challenging and are often up at all hours of the night and morning. Moving in bed is more difficult, getting comfortable takes effort. However, chemical changes in the brain can also affect the ability to enjoy normal sleep as well. This is a big problem because if you don’t sleep well it’s likely to worsen your Parkinson’s symptoms the next day.
·         Hallucinations – For some, chemical or neurological changes can cause hallucinations. First talk to your neurologist and there may be a change of medication recommended. Complications such as prolonged insomnia, fatigue, and progression of the disease may also lead to hallucinations.
·         Mood swings - The gradual loss of physical independence can force some to become increasingly reliant on others. This can create irritability, sadness, anger, and may manifest in mood swings due to feelings of guilt or frustration. Fear is also a common reaction, and "the patient may slowly become more dependent, fearful, indecisive and passive. They may talk less often, withdraw from family and friends and become less active even when encouraged to move about. They may feel lonely as they isolate themselves and as friends become more distant." (APDAA, 2014)
·         Slow thinking and/or short-term memory loss - Depression is often a major factor with the slowing of thought and memory impairment. However, it is only a contributor and it is the degenerative nature of PD that leads to slower and hazier thinking as well as memory loss. 
·         Fatigue - This is a physical symptom but also an emotional one. In his book "Brain and Behavior: Coping with Parkinson's disease" author Dr. Joseph Friedman identified fatigue as one of the biggest struggles for more than half of the patients interviewed. This fatigue was difficult to measure or track and led many patients to lose interest or motivation in everything from routine tasks to beloved hobbies.”
These non-motor symptoms of PD occur alongside the physical manifestations. However, you must realize that family members are not excluded from the emotional costs simply because they do not have PD.

Family members, serving as caregivers also face a tremendous amount of emotional strain. They may become frustrated, depressed or anxious, as well as fatigued, angry, overwhelmed, and deeply saddened.
Family members watch as a loved one becomes more dependent on others, losing interest in things that once brought joy. They may fight, or argue with the patient to keep up  healthy routines and exercise plans. Patience is very important as coping can take time.
Clearly, navigating through the emotional challenges of PD is something that no patient or family should do without proper resources, information, and support. In fact, the same list of experts and professionals as those offering treatment and therapy may be a first line resource.

Getting help  
                                                                    
Accept that PD absorbs a lot of your physical and mental energy, but you can find a path to family wellness. It is never easy to accept just how much is going to be asked of everyone in the family, but trying to resist help  only increase the emotional impact. Instead, it is far better to take the most obvious "next steps":
  • Take therapy and possibly seeing a psychiatrist for the patient is a vital first step. The high rate of depression and anxiety in PD patients means that antidepressant medications may be an important part of the adjustment process and a key to keeping the patient's quality of life as high as possible.
  • ·Additionally, the common problems with poor sleep can be addressed through medication regimens too, and this is also going to ensure a much better outcome for the patient and family.
  • ·A licensed mental health professional can assist in dealing with many problems. Though individual therapy is highly recommended, remember too that family therapy is one way to ensure that communication is clear, no misunderstandings are occurring, and that feelings are vented in a safe and productive environment.
  • ·Finding support groups is another next step. Both the patient and their family or caregivers need to be able to overcome frustrations, confusion, social isolation, and depression, and there is nothing like a support group full of "others" going through the same experiences to reduce stress, create wellbeing, and offer encouraging words and advice.
  • ·Create opportunities for care breaks. Respite from round the clock care is essential to any caregiver's wellbeing. A household or family in which one person serves as the primary caregiver must be organized enough to give that person some "down time" on a regular basis.
 Not only will this person benefit from therapy with a professional, but they should also have time to just go out and forget about the pressures and worries at home.

·Find ways of daily group exercise. A patient with PD must be encouraged to keep moving every day. A healthy way for a family to overcome some emotional challenges of PD is to exercise together every day or on a regular basis. This allows a caregiver to get a break from being the "pusher" if the patient is unwilling to exercise, plus it will allow the entire family to interact in a healthy and enjoyable way.
 "Parkinson’s disease requires a great deal of energy, and can greatly increase one’s stress level. Both the patient with Parkinson’s as well as their family members will more effectively manage the disease when we recognize their individual and collective needs for extra support."
Think of the PD diagnosis as something that requires a team effort. Every single member of the team is important to their overall success by focusing on the importance of wellness and emotional health for the patient and the family.
You may be unable to halt PD in its path, but you can prevent it from wreaking emotional havoc in the lives of those you love. Work with professionals as well as with each other, and you will find hope and a “new normal”.

A new drosophila model to study the interaction between genetic and environmental factors in Parkinson's disease.





Larvae






Fruit fly



 2014 Aug 14. pii: S0006-8993(14)01085-3. doi: 10.1016/j.brainres.2014.08.021. [Epub ahead of print]
The fruit fly Drosophila melanogaster has long been used as a model organism for human diseases, including Parkinson's disease (PD). Its short lifespan, simple maintenance, and the widespread availability of genetic tools allow researchers to study disease mechanisms as well as potential drug therapies. Many different PD models have already been developed, including ones utilizing mutated α-Syn and chronic exposure to rotenone. However, few animal models have been used to study interaction between the PD causing factors. In this study, we developed a new model of PD for use in the larval stage in order to study interaction between genetic and environmental factors. First, the 3rd instar larvae (90-94 hours after egg laying) expressing a mutated form of human α-Syn (A53T) in dopaminergic (DA) neurons were video-taped and quantified for locomotion (e.g. crawling pattern and speed) using ImageJ software. A53T mutant larvae showed locomotion deficits and also loss of DA neurons in age-dependent manner. Similarly, larvae chronically exposed to rotenone (10μM in food) showed age-dependent decline in locomotion accompanied by loss of DA neurons. We further show that combining the two models, by exposing A53T mutant larvae to rotenone, causes a much more severe PD phenotype (i.e. locomotor deficit). Our finding shows interaction between genetic and environmental factors underlying development of PD symptoms. This model can be used to further study mechanisms underlying the interaction between genes and different environmental PD factors, as well as to explore potential therapies for PD treatment.
