motor symptoms

Motor symptoms involve issues with movement resulting from problems in the brain’s motor control systems. These can include tremors (shaking), stiffness, slow movement, or difficulty initiating motion. Conditions like Parkinson’s disease cause dopamine loss, leading to tremors and rigidity. Other disorders may cause jerky or uncoordinated movements. Motor symptoms affect daily activities like walking, writing, or speaking, and can vary in intensity. They reflect underlying neurological changes impacting how nerves and muscles communicate to produce smooth, controlled movement.
