parkinson's disease

parkinson's disease is a progressive disorder of the nervous system that affects movement. it develops gradually, sometimes starting with a barely noticeable tremor in just one hand. tremors are common in parkinson's but the disorder also commonly causes stiffness or slowing of movement.

in the early stages of parkinson's disease, the face may show little or no expression, and the arms may not swing when walking. speech may become soft or slurred. parkinson's disease symptoms worsen as the condition progresses over time.

the cause of parkinson's disease is unknown, but several factors appear to play a role, including genetics and environmental triggers like exposure to certain toxins.

diagnosis is based on medical history, a review of signs and symptoms, and a neurological and physical examination. there are no tests specifically to diagnose parkinson's disease.

there's no cure for parkinson's disease, but medications can help control the symptoms. in some later cases, surgical procedures like deep brain stimulation may be recommended.
