Neurobehavioral Systems is a specialty “Neuropsychiatry” clinical group in Austin, Texas. “Neuropsychiatry” refers to a medical specialty which blends Psychiatry and Neurology. We treat both mental illness and brain problems. We specialize in successfully treating even very “hard to treat” children and teens. Most of our patients can be extremely irritable, moody and/or explosively aggressive. They may also be dangerously impulsive. Their behaviors may have resulted in multiple hospitalizations.

An important part of our patients’ improvement is that children are screened for risk factors that indicate a possible brain disorder that should respond to this approach. These risk factors include adoption, premature birth, difficult delivery, Epilepsy and multiple concussions.
