The first pattern is when developmental losses occur in the first 15 months to 3 years. [17] [18] The second pattern, childhood disintegrative disorder (a diagnosis now included under ASD in the DSM, but not the ICD), is characterized by regression after normal development in the first 3 to 4, or even up to 9 years of life.

Calcium: Incidence rates of calcium deficiency in children aged 0 to 3, 4 to 9 years and 10 to 15 years were estimated at 10.4%, 6.1% and 0.4% for boys and at 3.4%, 1.7% and 0.9% among girls. It has been found that special diets that are inappropriate for children with ASD usually result in excessive amounts of certain nutrients and persistent ...

[37] Similarly, another study found that exposure to violence in the community and the subsequent distress, were related to a significant decrease in intelligence scores and reading abilities in ...
An autistic three-year-old points to fish in an aquarium, as part of an experiment on the effect of intensive shared-attention training on language development. [ 57 ] There is no known cure for autism, [ 2 ] and very little research addressed long-term prognosis for classic autism. [ 58 ]
Children in the 2 years 6 months – 3 years 11 months age band are administered only five of the subtests: Receptive Vocabulary, Block Design, Information, Object Assembly, and Picture Naming. Quotient and Composite scores have a mean of 100 and a standard deviation of 15. Subtest scaled scores have a mean of 10 and a standard deviation of 3.
Additional vitamin-mineral supplementation may have an effect also in the developed world. A study giving such supplementation to "working class", primarily Hispanic, 6–12-year-old children in the United States for 3 months found an average increase of 2 to 3 IQ points. Most of this can be explained by the very large increase of a subgroup of ...
