Neurological disorders refer to a category of diseases and conditions that affect the central nervous system, which includes the brain and spinal cord. These disorders can impact a person's ability to move, speak, think, and feel, and can range in severity from mild to debilitating. Some common examples of neurological disorders include Alzheimer's disease, Parkinson's disease, epilepsy, multiple sclerosis, and stroke. Research in this area focuses on understanding the underlying mechanisms of these disorders, improving diagnosis and treatment options, and ultimately finding a cure for these debilitating conditions.
