Causes of PD can be nature or nurture.
Types of PD can be cluster A: eccentric/schizophrenic (MAD); paranoid PD, schizoid PD (detachment from social relationships, restricted range of emotion); schizotypal PD (uncomfortable in close relationships, perceptual distortions, eccentric behaviour). Cluster B: dramatic/psychopathic (BAD): antisocial PD; borderline PD; histrionic PD; narcissistic PD. Cluster C (SAD) is anxious/neurotic: avoidant personality disorder; dependent PD; OCPD.
