Neuropsychologists work closely with referring doctors to provide guidance on diagnosis and treatment for people with various illnesses, injuries, and diseases of the brain that can affect neurocognitive functioning (thinking skills), mood, behavior, and capability for independence.

Common conditions assessed by a neuropsychologist include dementia, concussion/brain injury, stroke, brain tumors, and Parkinson’s disease. Additionally, neuropsychological evaluations are required as part of a multidisciplinary pre-surgical evaluation for a number of conditions treated at St. Luke's, including for deep brain stimulation (DBS) surgery for movement disorders, epilepsy surgery, and as an important component of the lumbar drain trial for normal pressure hydrocephalus (NPH).

Because evaluating these conditions is complex, neuropsychological visits are broken up into three phases, all of which can be completed in either two or three visits depending on the needs of the patient.
