ADHD Comorbidities

  • Joseph Sadek


High rates of comorbidities with ADHD have been reported in both clinical samples and epidemiological studies. Authors such as Barkley (2002), indicated that comorbidity is generally high in ADHD in both children and adults. Several competing hypothesis are proposed to account for the patterns of comorbidity. Some suggested that maybe one disorder is an early manifestation of the other, development of one disorder increases the risk for the other, one disorder is a subtype of the other (conduct disorder and ADHD may be a subtype of ADHD), the comorbid disorders share common vulnerability factors or genetic and psychosocial factors, each disorder is an expression of phenotypic variability, or finally, each disorder is a separate entity.
