An electroencephalogram, or EEG, measures and records the electrical activity of the brain. As an outpatient procedure, an EEG is useful in confirming epilepsy, to study sleep disorders, to check for problems with loss of consciousness or dementia, to help find out if a person has problems in the brain, spinal cord, or nervous system, or to determine if a person has a mental health problem.
Evoked potential tests, or EVPs, help diagnose disorders of the nervous system, locate the site of nerve damage or brain tumors, evaluate a patient's condition after treatment or to monitor a patient during surgery. These tests measure the time it takes for nerves to respond to stimulation. Disease or other damage to the nervous system can affect how well nerves send messages to the brain. Muscle weakness, pain or numbness, vision or hearing problems, and other conditions may result. Nerves from different areas of the body may be tested.
TMC offers a number of EEG and EVP tests, including BAER (brainstem auditory evoked potential), visual, touch and hearing studies.
