WADA Test
The WADA test is typically performed before seizure surgery on the temporal lobe to test the temporal lobe functions of language and memory. During the WADA test, doctors put each half of the brain to sleep for a few minutes. This allows a neuropsychologist to test the language and memory functioning of each side of the temporal lobe in isolation. The results of the test show doctors how much of the language and memory functions are located in the right and left sides of the brain, and are used to determine how much of the temporal lobe can be removed. The Wada test is named after the neurologist Juhn A. Wada, MD, who first performed the test.
