Nervous System Diseases
Nervous system diseases are disorders that affect the brain, spinal cord, or nerves. Examples include Alzheimer disease, Parkinson disease, epilepsy, polio, stroke, and meningitis. These disorders can cause symptoms such as altered consciousness, headaches, issues with cognition and speech, memory loss, tremors, seizures, pain, numbness, or problems with movement. Causes vary widely and may include infections, trauma, metabolic disorders, autoimmune reactions, tumors, genetic mutations, or degeneration of nerve cells. Some diseases, such as stroke, develop suddenly, while others, like Parkinson disease, progress over time.
