Base rates of probable malingering and symptom exaggeration are reported from a survey of the American Board of Clinical Neuropsychology membership.

Treatment of post-concussion syndrome following mild head injury.

Approximately 38% of patients who sustain head trauma characterized by a brief disturbance of consciousness and clinically unremarkable neuroradiologic findings meet International Classification of Diseases 10th edition (ICD-10) diagnostic criteria for postconcussion syndrome (PCS). Physicians treat a majority of cases with nonsteroidal analgesics or antidepressants, and refer about 40% for psychological consultation. Psychological treatment typically involves education, reassurance, and reattribution of symptoms to benign causes.
