Symptoms
By Mayo Clinic staffEssential tremor symptoms:

Essential tremor vs. Parkinson's disease
Many people associate tremors with Parkinson's disease, but the two conditions differ in key ways:
- When tremors occur. Essential tremor of the hands typically occurs when your hands are in use. Tremors from Parkinson's are most prominent when your hands are at your sides or resting in your lap.
- Associated conditions. Essential tremor doesn't cause other health problems, whereas Parkinson's is associated with a stooped posture, slow movement and a shuffling gait.
- Parts of body affected. Essential tremor can involve your hands, head and voice. Tremors from Parkinson's typically affect your hands, but not your head or voice.
