[ADHD and personality disorders].

ADHD and personality disorders, like emotional unstable personality disorder and dissocial personality disorder, overlap to some extent but they also commonly co-occur in clinical populations. Prevalences, key issues in differential diagnosis, and the different aetiological background of the two categories are presented in this review.

In case of co-occurrence treatment, recommendations of both disorders and social support should be considered to achieve a patient-centered approach of the specific needs.
