Essential Tremor vs. Parkinson’s Disease (ET vs. PD) - Differences & Similarities

Both Essential Tremor and Parkinson's Disease are common movement disorders that affect many people around the world. Tremor shakes can happen at rest, while holding objects, and can also effect the head and the vocal cords. Neither of these movement disorders can be diagnosed with blood tests or MRI/CT brain imaging technologies. However, brain scans can help determine the origin of some movement disorders.
