Scans show what makes a brain “borderline”.

Brain regions that process anger and sadness are overactive in people with borderline personality disorder, a new study reveals.

The research also finds that the areas of the brain that would normally help dampen negative emotion are underactive. The work offers the best description yet of the neural circuits that underlie the severe mental illness and could lead to better treatments and diagnosis.
