Neurobehavioral Explanations of Personality Disorder


Notes from:

Simone Hoermann, Ph.D., Corinne E. Zupanick, Psy.D. & Mark Dombeck, Ph.D. Updated: Jan 3rd 2011

“Coccaro and Siever (2005) reported that researchers have identified a relationship between impulsive aggression and a complex neuro-chemical system called the serotonergic system. This finding suggests there is biological, neurological etiology for the symptom of impulsive aggression that is characteristic of Cluster B personality disorders.

Cluster B personality disorders are also characterized by emotional dys-regulation. Coccaro and Siever (2005) also reviewed brain imaging studies that found people with Cluster B personality disorders, had reductions in the volume of certain brain regions associated with the regulation of emotions. Once again, this finding offers compelling evidence for a biological explanation for the symptom of emotional dys-regulation.”

I wish H would seriously consider some low-level mediation that could help with his anger. My feelings are observational and I’m not that kind of doctor. Nonetheless, I’ve lived with him for several years. That’s worth something.
