List of Neurological Disorders

This list of neurological disorders is categorized based on the site of involvement of the individual diseases. The different areas of the nervous system include brain, spinal cord, peripheral nerves, muscle, NMJ (neuromuscular junction) etc.

Certain conditions may affect multiple regions so you may see the same disease again & again under several headings. For example you will come across MS (multiple sclerosis) under cerebral hemispheres, brain stem, cerebellum, spinal cord etc because this condition can involve all these above mentioned regions of the nervous system (of course not necessarily all these areas in the same patient). Strokes, tumors etc are few other such examples for neurological disorders that can involve multiple sites within the nervous system.
