Although Parkinson’s disease does not affect how long a person lives, it significantly impacts their quality of life. Here are the most common difficulties Parkinson’s patients struggle with.
Tremor

A tremor is one of the distinctive symptoms of Parkinson’s disease. It occurs due to movement problems caused by lower dopamine levels in the brain.

When the person is at rest, their hands may tremble slightly more than when performing tasks. A tremor may involve rubbing the thumb and forefinger back and forth (pill-rolling tremor).
