EEG (electroencephalogram)

A simple, painless test that measures and records the electrical activity of the brain. Sensors are attached to the patient’s head and hooked to a computer that measures the brain’s electrical activity. This test detects and monitors conditions such as seizures and sleep disorders such as narcolepsy.

EMG (electromyogram)

This test measures the electrical activity of muscles at rest and during contraction. It can help find diseases that damage muscle tissue and nerves. It can also help find the cause of weakness, paralysis, and muscle twitching.

Nerve Conduction Studies

This test is done to find damage to the nerves from the brain and spinal cord. This can help find nerve problems such as carpal tunnel syndrome.
