Neurological issues refer to problems that affect the nervous system, which includes the brain, spinal cord, and nerves. These issues can result from various factors, such as injury, infection, or genetic disorders. Common neurological conditions include epilepsy, multiple sclerosis, and Parkinson's disease, each affecting the body in different ways. Symptoms of neurological issues can vary widely and may include headaches, seizures, muscle weakness, or changes in behavior. Diagnosis often involves imaging tests like MRI or CT scans, along with neurological examinations. Treatment options may include medication, therapy, or surgery, depending on the specific condition and its severity.
