Neuropsychological tests are usually performed to evaluate neurological or neuropsychiatric disorders such as traumatic brain injury and brain concussion, multiple sclerosis and cerebral vascular accidents. The results often provide valuable information about the patient's neurocognitive functioning. Neuropsychological tests are also designed to evaluate a member's ability in concentration, memory, reading, comprehension, judgment, and ability to interpret and process information. Visual perception, movement, coordination and a psychological profile may also be performed. These tests make up a part of the overall medical evaluation, and the results aid in the development of a treatment plan.

Psychological tests are designed to measure a member's level of intelligence, personality, academic function and/or dimensions of psychopathology and attitudes and behavior. These tests make up a part of the overall evaluation process with results aiding in diagnosis and development of a treatment plan.
