The key difference between Parkinson's and essential tremor is when the shaking occurs. With Parkinson's disease, tremors happen while you're at rest - like when your hand is resting in your lap or on a chair arm, which matches what you're experiencing. With essential tremor, the shaking typically only happens when you try to use or move the affected body part, like reaching for a glass. Both conditions are diagnosed by neurologists, and it can sometimes be difficult to distinguish between them. There are specialized tests that doctors can use to help make an accurate diagnosis, including a DaT-SPECT scan that measures dopamine uptake in the brain, which is specifically impaired in Parkinson's disease. Given your symptoms and concerns, you may want to discuss getting this type of imaging with your healthcare provider. While both conditions can affect quality of life and worsen with stress, Parkinson's tremors rarely affect the head or voice, while essential tremor commonly does. Both conditions can exist simultaneously in some cases, though this is less common. If you're concerned about your diagnosis, seeking a second opinion from a movement disorder specialist might be helpful.
