Disturbed sense of identity in borderline personality disorder

Traditionally, personal identity is considered to be important for psychological health and adaptive functioning. Identity diffusion and other more severe forms of disturbance associated with personal identity are regarded as being essential parts of the borderline personality disorder. Moreover, disturbances in identity are seen as being part of the dynamic background for many of the symptoms and maladaptive behaviors found in borderline patients. It is argued, that the development of personal identity is intimately related to, and indeed dependent on, elements of modern culture, with significant cultural changes having affected the conditions under which human identity develops. Therefore, the identity diffusion seen in patients with borderline disorders must be understood in relation to not only the individual patient's personal history and inner structures but also contemporary late modern culture and social organization.
