Longitudinal Neurocognitive Findings of the CTD Patient

Age (years, months)	5y,0m	6y,1m	7y,2m	7y,10m	10y,6m
Nonverbal IQ (mean=100, SD=15)	43	38	35	34	42
Verbal IQ (mean=100, SD=15)	39	39	42	49	43
Vineland ABC (mean=100,SD=15)	52	52	62	64	60
ADOS Calibrated Severity Score (range=1–10)	1	2	2	2	-

Note: Nonverbal and Verbal IQ at age 5 and 6 were ratio scores from the Mullen Scales of Early Learning, at 7 were standard scores derived from the Differential Ability Scales, 2^nd edition, and at age 10 were standard scores from the Stanford Binet Intelligence Scales, Fifth Edition. Adaptive Behavior Composite was measured from the Vineland Adaptive Behavior Scales, 2^nd edition and ADOS=Autism Diagnostic Observation Schedule. The Calibrated Severity Score ranges from 1–10, with scores of 1–2 falling in the range of “minimal-to-no evidence of autism-related symptoms,” 3–4 “low level of autism spectrum-related symptoms,” 5–7 “moderate level of autism spectrum-related symptoms” and 8–10 “high level of autism spectrum-related symptoms.”
