Trends in Intellectual Development in Down Syndrome
Trends in Intellectual Development, and Diverging Verbal and Non-verbal Abilities in the Down Syndrome Phenotype
Previous foreign studies revealed that the IQ in Down syndrome (DS) declines with age, but not any investigation of domestic data in Taiwan was available. Individuals with DS are characterized by limited verbal development, and in this article, authors look into the diverging verbal-nonverbal abilities in the DS phenotype.
The present study investigated this by analysis the test results of development /intelligence scales. To compare initial cross-sectional data with longitudinal follow-up, about 12 people with DS were included.
