Any one may feel a little shaky when they are nervous, such as giving a talk first time to a group of people they don’t know. However, having a tremor in normal conditions is not normal. Tremor may be the first sign of Parkinson’s;thus, it should not be ignored.
Tremors are involuntary and rhythmic oscillations of muscles which induce an involuntary movement of a limb. Tremors can be due to many different causes. Two of the common causes of tremor are below,
-Essential tremor (ET) is the most common movement disorder, and is quite different from Parkinson’s disease tremor. Most cases of Essential Tremor are usually mild, and don’t require treatment. When symptoms do manifest they can include both postural
-Parkinson’s disease Tremor is typically a resting tremor and occurs when the affected body part is at rest. Resting tremor in Parkinson’s disease usually begins in one hand, arm or in a leg. A resting tremor usually dampens upon the initiation of a movement especially in the early stages of Parkinson’s. Resting tremor may just begin in thumb and/or index finger in some patients resembling pill rolling movements i.e. pill rolling tremor. The presence of a resting tremor in a patient with suspected Parkinson’s disease is supportive of the diagnosis. While tremor is the most common initial presenting symptom of Parkinson’s disease, only 70-80 % of patients have a resting tremor. The remaining 20-30 % of patients will demonstrate no signs of a tremor at all; making the identification of other symptoms essential. A tremor of Parkinson’s disease can involve the lips or chin, but usually does not involve head or voice.
