Dan Matthews

Dr. Dan Matthews, M.D.

Translating laboratory research into clinical applications, Dr. Daniel Matthews has pioneered the successful treatment of childhood limbic rage syndrome, which as of DSM 5, largely meets the criteria for a diagnosis of Disruptive mood Dysregulation Disorder. Dr. Matthews’ procedures are to evaluate, diagnose and treat identified electrical abnormalities, much like treatment of a seizure disorder, rather than as a learned or behavioral disorder.

By using the Cognitrace System, a quantitative electroencephalograph (qEEG) for deep or limbic brain electrical activity analysis, with auditory and visual evoked responses, in addition to routine EEG, and appropriate mood stabilizing, anti-seizure medications, Dr. Matthews’ methods have demonstrated a reduction in the frequency and severity of pathological aggression in over 80 percent of medication compliant patients followed in the last twenty years. Since the early 1970’s, his research into specialized assessments and medical stabilization of impulsive, explosive pathological violence led to his development of new therapeutic procedures which have become national standards of care for these children and adolescents.

Before joining UHS in 1995, Dr. Matthews was medical director for psychiatric treatment centers in Texas and North Carolina, and maintained a private practice. Previously, he was a clinical associate professor at Duke University School of Medicine, and was the state’s psychiatric consultant to the Willie M federal class action suit for North Carolina state programs that dealt with violent youth.

Dr. Matthews received his medical degree at the University of Texas Medical Branch at Galveston. He completed two years of residency in general psychiatry followed by two residency years in child psychiatry at the University of Texas Medical Branch hospital.

His research on aggressive and violent children and adolescents has been presented nationally and internationally at major neuropsychiatry, psychiatry and behavioral conferences, and published in leading psychiatric journals. He is a member of the American Neuropsychiatric Association and the Titus Harris Medical Society.

Heather is usually the first voice parents and professionals speak with in contacting our office. Her many roles include assisting parents who wish to obtain outpatient Neuropsychiatric Testing for their child. This also involves arranging for a collaborative relationship with the referring prescriber on behalf of the child.
