Tremor can be an early sign of Parkinson's disese, but tremor comes in many forms and can have many causes. Tremor in Parkinson's disease usually begins unilaterally (on one side of the body) such as in one hand. Tremor in Parkinson's disease is usually described as a ‘resting tremor’ because it is generally worse when the body part is resting, e.g. resting in one's lap, and may momentarily improve when the body part is used, e.g. the tremor may improve for a few seconds when the person holds out their arm such as when changing the TV channel with the remote control. Other forms of tremor include essential tremor, which is usually worse when the the body part is in action - picking up and drinking a cup of water is characteristically difficult for these patients. Other common causes of tremor include anxiety, medication side effects, metabolic disturbances, caffeine, sleep deprivation, stress and many others. If you are concerned I would recommend seeing your GP who could refer to a movement disorders specialist such as a neurologist or geriatrician for a more definitive diagnosis and appropriate treatment.
