slowing movements, which is a key symptom of several neurological diseases, especially Parkinson’s disease. It involves a gradual decrease in the speed and amplitude of voluntary movements, making it difficult to start, perform, or complete tasks. Bradykinesia can manifest itself in a variety of ways, including slow walking, difficulty with fine motor skills (such as buttoning or writing), and decreased facial expressions (often resulting in a “mask-like” appearance). The condition is thought to be caused by dysfunction of the basal ganglia, a group of structures involved in motor control. Treatment usually includes medications such as dopamine or levodopa agonists, as well as physical therapy to improve movement and maintain mobility.
