Although the precise cause of personality disorders isn't known, certain factors seem to increase the risk of developing or triggering personality disorders, including:

  • Family history of personality disorders or other mental illness
  • Low level of education and lower social and economic status
  • Verbal, physical or sexual abuse during childhood
  • Neglect or an unstable or chaotic family life during childhood
  • Being diagnosed with childhood conduct disorder
  • Variations in brain chemistry and structure

Personality disorders usually begin in the teen years or early adulthood.
