The goals of a neuropsychological evaluation are to 1) measure the presence and degree of impairment due to organic disease or injury of the brain, 2) document individual strengths and weaknesses and 3) help in the distinction between functional and behavioral difficulties attributed to organic processes and personality factors. Evaluations differ depending on the individual's age and the nature of the problem. Domains evaluated include but are not limited to general intelligence, attention and concentration, processing speed, memory, abstract reasoning, executive functions, language, sensory functions and fine motor skills, academic skills and personality factors.
