What condition is characterized by movement disorders and masks facial expressions?

Parkinson's disease is characterized by movement disorders due to the degeneration of certain areas of the brain that produce dopamine, which is crucial for controlling movement. One of the hallmark symptoms of Parkinson's disease is bradykinesia, or slowness of movement, which affects both voluntary and involuntary muscle control. This leads to a distinctive "mask-like" facial expression where individuals may have reduced facial mobility and difficulty in exhibiting emotions through facial expressions, often referred to as "facial masking."

In addition to the movements, individuals with Parkinson's may experience tremors, stiffness, and balance issues, all of which significantly impact their daily life and activities. These movement-related symptoms distinguish it from other conditions on the list, making it specific to Parkinson's disease. The other options pertain to mental health or are related to different neurological conditions that do not primarily involve the same movement disorders or facial expression changes.
