Tremors in Parkinson’s Disease


Tremors are among the commonest symptoms of Parkinson’s disease. In the above video, you can see tremors affecting the right hand in a middle aged woman suffering from Parkinson’s disease. These are also called as “drum-beating” tremors. The frequency of these tremors is 4-5 Hz. There are no tremors in the left hand. These tremors are present only at rest, and they disappear while performing an action (unlike essential tremors, which get worse on performing an action).

I am a doctor with 25 years experience. I have worked as a neurologist for about 20 years. Educating public and healthcare professionals is very dear to me. This is possible due to my interactions with thousands of patients and their caregivers. I salute the patients who suffer and it is our duty to minimise suffering by preventing diseases and ensuring prompt diagnosis and treatment of those already affected.
