Bradykinesia is a symptom characterized by slowness of movement, often associated with neurological conditions such as Parkinson's disease. It manifests as a reduction in spontaneous movement and can affect activities of daily living, making tasks more time-consuming and difficult. Individuals may experience a decrease in facial expressions and a shuffling gait. Bradykinesia is one of the key features used in diagnosing Parkinson's disease and can significantly impact a person's quality of life.
