Nervous System Problems - Topic Overview

Seizures can also cause sudden changes in consciousness, feeling (sensation), emotion, or thought. Abnormal body movements, such as muscle twitching, may or may not be present. How often the seizures occur and how severe they are depend on the cause of the seizures and the area of the brain involved. For more information, see the topic Seizures.

Diabetes can cause problems with balance, either as a result of peripheral neuropathy or stroke.

Vertigo and dizziness are problems of balance and coordination (equilibrium). Vertigo is often caused by a medicine or a problem of the inner ear or brain. Emotional distress, dehydration, blood pressure problems, and other diseases can all cause feelings of dizziness. For more information, see the topic Dizziness: Lightheadedness and Vertigo.

Most headaches are not caused by serious central nervous system problems. The pain that comes with a headache can range from a throbbing or a piercing pain, such as with a migraine, to severe pain that comes and goes over several days, such as with cluster headaches. Headaches are usually caused by problems with the sinuses, scalp, or muscles of or around the head. For more information, see the topic Headaches.
