A neurological disorder is a condition that affects the nervous system, which includes the brain, spinal cord, and nerves. These disorders can disrupt normal functioning and may lead to symptoms such as difficulty with movement, coordination, or communication. Examples include epilepsy, Parkinson's disease, and multiple sclerosis. The causes of neurological disorders can vary widely, ranging from genetic factors to infections or injuries. Diagnosis often involves medical history, physical exams, and imaging tests like MRI or CT scans. Treatment options may include medications, therapy, or surgery, depending on the specific disorder and its severity.
