Parkinson's Disease: Symptoms and Causes

One of the most common symptoms of Parkinson's disease is tremors or shaking in the hands, arms, legs, jaw, or face.

Another common symptom of Parkinson's disease is slow movement or bradykinesia. People with Parkinson's disease may find it difficult to initiate movements.

Parkinson's disease can also cause muscle rigidity, which can lead to stiffness, pain, and difficulty with movement.

Parkinson's disease can also affect speech and writing, causing changes in tone, volume, and clarity.

Parkinson's disease can also cause sleep disturbances, such as insomnia, restless leg syndrome, and sleep apnea.

In some cases, Parkinson's disease can cause cognitive changes, such as memory loss, confusion, and dementia.

Parkinson's disease is caused by a loss of dopamine-producing neurons in the brain, which leads to the characteristic symptoms of the disease.
