HOLGUIN ACOSTA, JORGE et al. Comorbidity of attention deficit hyperactivity disorder in a childhood and adolescent student population based sample, Colombia, 2001. Iatreia [online]. 2007, vol.20, n.2, pp.101-110. ISSN 0121-0793.

THDA is frequently accompanied by comorbid conditions like oppositional defiant disorder, conduct disorder, affective disorders, dyslexia and Gilles de la Tourette syndrome. A comprehensive evaluation of these associations is important to guide the treatment and has relevance in the prognosis. The prevalence in Sabaneta, Colombia, is 15%. It makes THDA the most frequent neurobehavioural disorder in childhood. METHODS: Descriptive, transversal study. Sample: random representative, poliaged, proportional according to group size for primary school students between 4 and 17 years of age. First stage ADHD screening checklist according to DSM-IV criteria. Second stage: structured neuropsychological interview, Conner´s checklist and intelligence quotient. The interview included DSM-IV diagnostic criteria for comorbidity. RESULTS: learning disorder was the most frequent comorbidity (15,1%), followed by oppositional defiant disorder (5%), generalized anxiety (2,7%), conduct disorders (2,7%), phobias (2,3), depression (1,8%), bipolar disorder (1,8%). Epilepsy and obsessive compulsive disorder represented each 0,9%. CONCLUSION: Learning Disorder is the most frequent comorbidity in children with THDA. The search for this comorbid condition represents a central hallmark in the successful evaluation and treatment of this condition.
