Borderline personality disorder is a heritable brain disease

Author and Disclosure Information



The G.E interaction model appears to be consistent with the theory that ex­pression of plasticity genes is modified by childhood experiences and environ­ment, such as physical or sexual abuse. Some studies have found evidence of hypermethylation in BPD, which can ex­ert epigenetic effects. Childhood abuse might, therefore, disrupt certain neuro­plasticity genes, culminating in morpho­logical, neurochemical, metabolic, and white-matter aberrations—leading to pathological behavioral patterns identi­fied as BPD.

The neuropsychiatric basis of BPD must guide treatment
There is no such thing as a purely psycho­logical disorder: Invariably, it is an abnor­mality of brain circuits that disrupts normal development of emotions, thought, behavior, and social cognition. BPD is an exemplar of such neuropsychiatric illness, and treat­ment should support psychotherapeutic ap­proaches to mend the mind at the same time it moves aggressively to repair the brain.
