ABSTRACT

Objective: To examine the differences on clinical features between DSM-Ⅳ ADHD and ICD-10 HKD patients. Methods:516 children referred to psychiatric clinic because of overactivity, inattention, and impulsivity symptoms were divided into two groups Children meeting both criteria ( HKD-ADHD group, n=199), and children meeting only DSM-Ⅳ ADHD criteria (ADHD group, n=317). Diagnoses were confirmed by structured interview with parents using Clinical Diagnostic Interview Scale. Results: Whereas the combined type is predominant in HKD-ADHD group (75.4%), predominately inattentive type take account of the majority in ADHD group (67.2%). Compared to ADHD group, HKD-ADHD group includes the patients with younger referral age(9.6?2.2 vs 10.7?2.6) and earlier onset of age(4.6?1.9 vs 5.9?2.5), more opposite defiant disorder comorbidity (41.2% vs 26.2%), more disturbed behaviors, and higher sensory integrative dysfunction prevalence (72.6% vs 56.9% ). However, among the patients not older than 9-year-old there is higher prevalence of learning disability in ADHD group (26.7% vs 14.8%).Conclusion: ICD-10 criteria identified a severe group of patients than those identified by DSM-Ⅳ.However, the patients satisfied only DSM-Ⅳcriteria has exhibited more academic difficulty and behavioral disturbance compared with normal children, so we recommend DSM-Ⅳ as clinical diagnostic tool so that earlier interventions could be possible.
