Abstract:

Introduction . A high comorbidity has been observed among attention - deficit hyperactivity disorder ( ADHD ) and categorical personality disorders ( PD ) . A study is conducted on the dimensional traits associated with ADHD and PD , in order to determine whether there are any differences . Methodology . A cross - sectional study was conducted on 78 outpatients attending a Mental Health Clinic in Arganda ( Madrid ) from January 2013 to June 2015 . ADHD diagnosis was evaluated with the CAARS , the CAADID , and the WURS scales , and the PD with the SCID - II - DSM - IV questionnaire . None of the patients were receiving any stimulant or atomoxetine before the study , and all patients signed the informed consent before the study . Results . A high comorbidity was found with all PD clusters , especially with hyperactive and combined type ADHD . Depressive PD was associated with inattentive ADHD . Conclusions . In spite of using a questionnaire to evaluate PD , some differences can be observed between specific ADHD types and PD . More studies are needed to investigate dimensional personality traits in order to improve the diagnosis and therapeutics goals .
