Developmental trajectories in siblings of children with autism: cognition and language from 4 months to 7 years.

Gamliel I, Yirmiya N, Jaffe DH, Manor O, Sigman M - J Autism Dev Disord (2009)

Bottom Line: At 7 years, 40% of the SIBS-A, compared to 16% of SIBS-TD, were identified with cognitive, language and/or academic difficulties, identified using direct tests and/or parental reports.This sub-group was identified as SIBS-A-broad phenotype (BP).Results indicated that early language scores (14-54 months), but not cognitive scores of SIBS-A-BP and SIBS-A-nonBP were significantly lower compared to the language scores of SIBS-TD, and that the rate of development was also significantly different, thus pinpointing language as a major area of difficulty for SIBS-A during the preschool years.

ABSTRACT
We compared the cognitive and language development at 4, 14, 24, 36, 54 months, and 7 years of siblings of children with autism (SIBS-A) to that of siblings of children with typical development (SIBS-TD) using growth curve analyses. At 7 years, 40% of the SIBS-A, compared to 16% of SIBS-TD, were identified with cognitive, language and/or academic difficulties, identified using direct tests and/or parental reports. This sub-group was identified as SIBS-A-broad phenotype (BP). Results indicated that early language scores (14-54 months), but not cognitive scores of SIBS-A-BP and SIBS-A-nonBP were significantly lower compared to the language scores of SIBS-TD, and that the rate of development was also significantly different, thus pinpointing language as a major area of difficulty for SIBS-A during the preschool years.

Mentions: The resultant growth curves yielded no significant differences between the three groups’ cognitive scores over time (4–54 months), for any of the three models (Table 3). Furthermore, the growth curves over time for the overall pattern of cognitive development showed a similar U-shape and were parallel for the three groups, thus indicating a similar rate of change over the years (Figs. 1, 2, 3).Fig. 1
