Neuropsychologist:

"Clinical neuropsychology is a specialty profession that focuses on brain functioning. A clinical neuropsychologist is a licensed psychologist with expertise in how behavior and skills are related to brain structures and systems. In clinical neuropsychology, brain function is evaluated by objectively testing memory and thinking skills. A very detailed assessment of abilities is done, and the pattern of strengths and weaknesses is used in important health areas, such as diagnosis and treatment planning. The clinical neuropsychologist conducts the evaluation and makes recommendations. He or she may also provide treatment, such as cognitive rehabilitation, behavior management, or psychotherapy."

With a goal of determining the nature and extent of damage, and the impact upon intellectual and personality functions, the neuropsychologist works to pinpoint the cognitive alterations and lead the individual and his/her family to a better of understanding of how every day performance has changed. Many times these cognitive alterations have no physical or physiological explanations that neurologists or psychiatrists can trace during their own examinations. Based on behavioral observation of the patient, the neuropsychologist's evaluation and guidance assists in providing more effective rehabilitation and, thus, a more complete and successful recovery.
