"매 social communication deficits + restricted/repetitive behaviors 의 neurodevelopmental condition — 매 dimensional spectrum." 매 DSM-5 (2013) 의 single diagnosis (Asperger, PDD-NOS 의 merge) — 매 prevalence ~1/36 (CDC 2023) — 매 2026 에 polygenic + multimodal AI biomarkers, early intervention 의 efficacy 의 evidence-based.
매 핵심
매 DSM-5 criteria
A. Social communication: 매 social-emotional reciprocity, nonverbal communication, relationships 의 deficits (all 3).
B. Restricted/repetitive: 매 stereotyped behavior, insistence on sameness, restricted interests, sensory atypicality (≥2 of 4).
C. Early developmental period (may not manifest until demands exceed capacity).
D. Functional impairment.
E. Not better explained by ID/global delay.
매 levels of support
Level 1: requiring support.
Level 2: requiring substantial support.
Level 3: requiring very substantial support.
매 응용
Early screening (M-CHAT, ADOS-2).
Multimodal AI diagnosis (eye-tracking + voice + behavioral).
Personalized intervention (ABA, ESDM, JASPER).

매 결정 기준
상황
Approach
Toddler screen
M-CHAT-R/F at 18 + 24 months
Diagnostic confirm
ADOS-2 + ADI-R (gold standard)
Early intervention (<3y)
ESDM (Early Start Denver Model)
School-age
ABA, social skills groups, IEP
Co-occurring anxiety
CBT (modified), SSRI
Aggression / SIB
FBA + behavioral plan; meds last
기본값: 매 early screen → multidisciplinary eval → individualized plan.
