Shaky Hand Explained: ET vs Parkinson's Difference

Essential Tremor (ET) is a common movement disorder, while Parkinson's disease is a neurodegenerative disorder.

ET typically affects the hands, arms, and head, while Parkinson's tremors often start in one limb.

ET tremors are usually action tremors, occurring during movement or posture.

Parkinson's tremors are typically resting tremors, occurring when the limb is at rest.

ET tremors are often bilateral, affecting both sides of the body.

Parkinson's tremors often start unilaterally and may remain asymmetric.

ET tremors are usually faster, with a frequency of 4-12 Hz.

Parkinson's tremors are typically slower, with a frequency of 3-6 Hz.

ET is often hereditary, with a family history of tremors.

Parkinson's disease is usually sporadic, but can have genetic components.
