Neuropsychological evaluations occur either at the Medstar Georgetown University Hospital or at NAF’s main office in Fairfax, VA.

The NAF team conducts neuropsychological evaluations that involve the assessment of general intellectual functioning, executive functioning, attention/concentration, learning and memory, language, and mood/personality. Such an evaluation is typically recommended for cases where brain-based impairment in cognitive function or behavior is suspected. Referrals are made to evaluate an individual’s cognitive functioning in order to aid in the diagnosis or to rule-out various medical conditions.
