Neurological, cognitive, and psychiatric conditions

Conditions We Evaluate

Our neuropsychologists evaluate and diagnose the full range of cognitive and behavioral conditions, including Alzheimer’s disease, stroke, Parkinson’s disease, epilepsy, traumatic brain injury (TBI), attention-deficit/hyperactivity disorder (ADHD), and post-traumatic stress disorder (PTSD). Testing is interpreted against normative data and in the context of the patient’s medical history, education, and presenting concerns.
