Neuropsychology

Neuropsychologist and patient

Neuropsychologists help test brain function when a patient has symptoms or complaints involving memory or thinking. These concerns may be signaled by a change in concentration, organization, reasoning, memory, language, perception, coordination, or personality. Our experts will test memory and thinking skills to help identify a pattern of strengths and weaknesses and develop a treatment plan.
