[P2-12] A Follow-up Study of Attention Deficit Hyperactive Disorder Children: Differences from High Function Autism Spectrum Disorder
[Purpose] To clarify differences in clinical course from the onset to the adolescence between attention deficit hyperactive disorder (ADHD) and high function autism spectrum disorder (ASD). [Subjects] Eighteen cases of ADHD and 16 cases of ASD with followed-up to 15 years of age or older [Method] We compared clinical features between ADHD and ASD cases retrospectively. [Results] 1) Initial symptoms were speech retardation or disappearance in 26% of ADHD and in 22% of ASD, and hyperactivity in 37% and 22%, respectively. Panic, temper tantrum was observed in 33% of ASD, exclusively. 2) Mentally borderline retarded children tended to be more frequently observed in ASD (39%) than in ADHD (19%). 3) During school age, both of inattention rating scale and hyperactivity/impulsivity rating scale were higher in the ADHD while autism score (ASSQ) was so in ASD – although not significant. 4) Methylphenidate and atomoxetine were more frequently prescribed for ADHD children. 5) With regard to behavior at the adolescence, inattention was equally recognized both in the two groups (56%), and hyperactivity/impulsivity was more frequent in the ASD (72%) than in the ADHD (36%). Tantrum/panic/violence was more commonly experienced by ASD (69%), more than ADHD (19%). [Conclusions] Temper tantrum/ panic was more prominent characteristic for ASD than for ADHD from the onset to the adolescence. At the adolescence, inattention was present to the same degree in the two groups while hyperactivity/impulsivity was more prevailing in ASD.
