The aim of this study was to examine the two points in DSM-5 (Diagnosis and Statistical Manual of Mental Disorders, 5-th. ed.) diagnostic standard. The first point is that the severity level for intellectual disability is determined by adaptive functioning rather than IQ scores. The second point is that the autistic disorder is determined by deficits in two core domains (a: social communication and social interaction, b: restricted, repetitive patterns of behavior), but they cannot be used for determining whether to make diagnosis function at predetermined items.
