Abstract
Objectives: This study is to understand the clinical characteristics and course of inpatient severe ADHD.

Methods: This study retrospectively investigated the chief complaints, history, demographics, neuropsychologic test, psychosocial status of 63 (male 58, female 5) inpatients from a single center with severe attention deficit/hyperactivity disorder(ADHD) during January 1, 1996 to October 31, 2002.

Results: The patients with inpatient severe ADHD revealed a male to female ratio of 11.6 : 1 and the average age of onset was 5.3 years(63.6 months, SD 24.3 months) . Comorbidities were noted in 56/63 (88.9%) patients with the following frequencies : comorbid conduct disorder, 35(55.6%), mental retardation (MR), 24(38.1%), mood disorder, 5(7.9%), tic and Tourette¡¯¡¯s disorder, 4(6.4%), oppositional defiant disorder, 4(5.0%). Chief complaints for admission related to ADHD in 23(36.5%) patients while 37(58.7%) patients admitted due to symptoms associated to conduct disorder (CD). The mean onset age of comorbid delinquency was 9.0 years (108.2 months, SD28.8 months), and the average interval between onsets of ADHD and delinquency was 3.6 years (42.9 months, SD32.0 months). Patients who showed early delinquency tended to have an earlier onset of ADHD (p<0.05).

Conclusion: The demographics, natural course, and psychosocial factors of hospitalized ADHD patients were similar to prior studies of ADHD in the general population. The onset of age was 5.3 years, and the onset of comorbid delinquency was 9.0 years. The earlier symptoms of ADHD manifested, the earlier delinquency appeared. Most patients were admitted due to chief complaints related to CD. Comorbidities, most of which were CD, were seen in 88.9% of the patients.
