Behavioural Neurology of Personality Disorders: A Bi-dimensional Model

Khalid A Mansour

This study explored a new scientific approach for analysing mental disorders, as a possible way to modernise Kraepelinian psychiatry, using neurobehavioral principles to develop a model of personality (and personality disorders), as an example. The model uses a two-dimensional approach (behavioural and pathophysiological) to define personality disorders, instead of the prevailing one-dimensional (behavioural) approach used in Kraepelinian psychiatry. The model is also biological, socio-neurodevelopmental, and dimensional (non-categorical) and aims to integrate with clinical principles to the extent possible. The model begins from a platform of three origins of personality and personality disorders: basic skills (visceral, physical, and emotional and social intelligence), maturity, and environment. The model incorporates modern discoveries of neurosciences and makes them more amenable to clinical practice.
