| Abstract |
Comorbidity in Different Presentations of Attention Deficit Hyperactivity Disorder Objectives: More than half of the subjects with Attention Deficit and Hyperactivity Disorder (ADHD) have psychiatric comorbidity. Subjects with comorbid disorders are likely to experience greater occupational impairment, compared to people with ADHD alone. Rates and patterns of comorbidity may change among different presentations of ADHD. In this study, we aimed to investigate several clinical characteristics such as age of onset and rates and patterns of psychiatric comorbidity in a clinical sample of young subjects diagnosed with ADHD. Methods: The study included 154 subjects, 6–18 years of age with diagnosis of ADHD according to DSM-V criteria who have been diagnosed and/or followed up in Istanbul Faculty of Medicine, Department of Child and Adolescent Psychiatry. Subjects with diagnoses of intellectual disability or autism spectrum disorders were excluded. Schedule for Affective Disorders and Schizophrenia for School Aged Children- Now and Lifetime Version was used in psychiatric assessment. Results: 78 percent of subjects had at least one lifetime psychiatric comorbidity. Mean lifetime psychiatric diagnosis was 2,69±1,34. Most common co-occuring diagnoses were enuresis nocturna (%21,4), generalized anxiety disorder (%20,8) and oppositional defiant disorder (ODD) (%15,6). When psychiatric diagnoses were compared by gender; depression and social anxiety disorder were higher in females; and rates of ADHD combined presentation was higher in males. When we compare comorbid diagnoses by age groups; diagnosis of enuresis was found higher in children. When we compare comorbid diagnoses by different presentations; rates of generalized and social anxiety disorders were higher in ADHD predominantly inattention presentation, and rates of enuresis nocturna, encopresis and ODD were higher in ADHD combined presentation. Conclusion: ADHD is commonly accompanied by other psychiatric disorders in clinically referred subjects. While inattention presentation of ADHD is more often comorbid with internalizing disorders (such as anxiety disorders), combined presentation is more often comorbid with externalizing disorders (such as ODD). Awareness of comorbidities of ADHD and knowing that clinical features and psychiatric comorbidites may vary among different clinical presentations may help defining subtle symptoms, modify treatment plan and improve prognosis. |
