A neuropsychological evaluation is a way of checking for symptoms such as memory loss, or difficulties with speaking, reasoning, or paying attention. You may not have any of these problems; sometimes they are only suspected. The examination consists primarily of answering questions, completing paper-and-pencil tasks, and solving various kinds of problems. This evaluation is structured to help us determine if you are having difficulties that may be important for your health care providers to consider in your diagnosis and treatment. The interview and evaluation will take approximately 3 hours. You may be asked to return on another day for further evaluation if we feel it is warranted.
