Treating Parkinson's, then, is a matter of producing dopamine in the brain.
A key of Parkinson's treatment is the drug
levodopa, which is converted into dopamine in the brain and is "the cornerstone" of Parkinson's therapy, says Factor. Accordingly, he has prescribed it for Schulman along with a second drug, rotigotine.
Parkinson's patients experience "ons and offs," said Factor: motor fluctuations in response to the drug. These fluctuations appear as involuntary movements, known as dyskinesia. Actor and Parkinson's patient
Michael J. Fox has this symptom and writes in his autobiography about overmedicating with levodopa early in his diagnosis to "cover" his symptoms and keep working.
Some researchers believe dyskinesia is caused by medication flowing in waves or pulses in the brain. Some believe that taking too much levodopa causes dyskinesia.
ne of the big discussions in the field is whether and when to start treatment with levodopa, Factor explained, since the drug contributes to dyskinesia. But it is not the only cause.
"I personally believe that the progressive nature of each individual's disease predestines them to get it at some point," Factor said. "So if you delay the levodopa to try and prevent it, you're not going to prevent it, and you're going to lose a period of time when patients can have a really good response."
He tends to use it early, to give young patients the best opportunity to continue working. To limit the dose and delay fluctuations, he adds a second drug to the regimen.
Another reason for giving levodopa to young-onset patients is that they can undergo deep brain stimulation surgery once the fluctuations become troublesome.
"Young people are the best candidates, because they are healthy and will have long-term benefits from the surgery," Factor said.
As Gilbert explains, delivery of medication is one of the most important areas of Parkinson's research right now. The goal is finding a way to deliver medication that stimulates the production of dopamine within the brain in a more continuous, sustained way. Among the new delivery systems, pharmaceutical researchers have developed infusion systems to pump medication directly into the small intestines.
One new class of drugs under development is chemically similar to caffeine, says Factor, because caffeine appears to lower the risk of getting Parkinson's disease in people with certain genes. Surprisingly, nicotine and other environmental toxicants may have a similar effect, lowering the risk for people with a certain genetic profile.
"We very rarely see Parkinson's disease in active smokers," Factor said.
From Schulman's perspective, all the research focused on medication is somewhat disappointing.
"It's all symptom management," she said, adding that she doesn't expect a cure in her lifetime. Despite recent advances in neuroscience, a
cure for this complex disease is not on the horizon.
At the same time, even though she knows "there's no reason to suffer and it's not necessarily going to get worse if you begin to take levodopa right now," she still has some worry about taking too much levodopa.
"The tremor is annoying when I'm out at a restaurant with friends and my meds are wearing off," Schulman said. "I can feel myself moving, so I try to sit on my hand.
"It's also hard taking all these meds regularly. It's like three times a day," she said. "But I'm dealing with it and functioning."
Prognosis
"Everyone who is born holds dual citizenship, in the kingdom of the well and in the kingdom of the sick," Susan Sontag wrote in her book "
Illness as Metaphor," adding that sooner or later, each of us will count ourselves among the citizens in the country of sickness.
But not everyone in the kingdom of the sick believes the stamp on her passport.
"There's still part of me that doesn't believe that I have Parkinson's," Schulman admitted. "I just have that percentage that still thinks they all got it wrong and maybe it's something else.
"I'm trying to get over this denial phase, because I think I've been in it a little too long."
In January, she will leave her job as a preschool teacher and start focusing on "going to the gym every day and getting a trainer and start moving more and taking it a little more seriously."
Exercise is the best thing Parkinson's patients can do for themselves, according to Gilbert, who says, "lots and lots of things are improved when patients exercise." Many studies have showed that exercise improves symptoms of depression, helps with cognition and slows the progression of motor symptoms.
Although Factor refers to her symptoms as mild, Schulman says, "to me, it's pretty not mild, because I feel them." She noticed that her tremor has worsened since her diagnosis in early 2015 and asked Factor if that meant she is progressing quickly.
"It's slow and slower, that's what he said: People progress slow or slower," Schulman said. "They don't know how much I'll progress. They don't know if I'll stay this way and never get worse. They know to a point you do get worse, but everybody's different. Two years from now, I could be a lot worse or be where I'm at right now."
"The hardest part for me is not even so much that I have Parkinson's disease, it's my kids," said Schulman, who has an 11-year-old son, a 10-year-old son, a 7-year-old daughter and a 3-year-old son. Each knows in some way about their mother's disease.
"My oldest is aware. I sat with him once, and I talked to him about it, and he started crying actually, and he asked me if I was gonna die, and I said 'no, I'm not gonna die,' " she said. "The other ones know, but they don't really know so much about it.
"I cried a lot thinking now my kids are going to have a mom who is sick, someone who is not going to be able to do things they want me to do," she said. "I feel so bad for my husband. We've been married for 15 years, and now he has a wife with Parkinson's."
Most people die with Parkinson's disease, not because of it, says Factor. Still, people with very long-term Parkinson's can develop dementia or lose their ability to walk and then may get complications of immobility, such as pneumonia or other infections.
"They say you don't die from Parkinson's, but ..." Schulman said with a laugh. "I sort of disagree."
Everywhere on the groups she's joined -- a Facebook group and other chat rooms -- family members say their loved ones died from complications of the disease.
"I just hope that I progress slowly enough that there will be better medicine to help," she said.
Meanwhile, she still finds it embarrassing to say she has Parkinson's, because "people envision an old person shaking and looking a little funny."
"I want to be one of those personalities, those people who are like a fighter and gung ho and raising money and supporting the foundation and out there about it."
"I want to be that way," Schulman said. "I'm just not there yet."
