The Wada test is used to determine which side of the brain controls language function and how important each side of the brain is in regard to memory function.
How to prepare for a Wada
The night before a Wada procedure, you will be asked to not eat or drink after midnight (with the exception of sips of water with medications). The morning of the procedure, it is important to take your anti-seizure medications as prescribed by your neurologist.
When you arrive at the Interventional Radiology Department, you will meet with the neurointerventional radiologist, the anesthesiologist and your epileptologist. Before the procedure, you will have EEG leads applied to your scalp and an IV placed. The procedure involves a catheter being placed into your groin. Following the procedure, you will be asked to lay flat for several hours before going home.
