Wada Testing

The Wada Test is also known as an intracarotid amytal test. Developed by Dr. Juhn Wada, a neurologist, in the 1940s, the test was originally done to determine which side of the brain controlled speech. Today, the Wada test is used to test memory as well as language functions.

It is a valuable tool in the evaluation of patients who are being considered for epilepsy surgery because it can help examine the independent functions of the side of the brain that is targeted for surgery.

Reasons for the Wada Test

• To determine the memory and language functions in each side of your brain
• To determine how each side of your brain works independently
• To trace the arteries that supply blood to each side of your brain
• This test is being done as part of the evaluation for epilepsy surgery.
