Recent medical advances, as well as cultural and institutional support for people with Down syndrome and their families, provides many opportunities to help overcome the challenges of this condition.
Usually, all cells in an individual have the same unique genome - all same chromosomes from the moment of conception. Does any, or all of the variability in neurological deficits has to do with the stochastic process of? Down is caused by all or part of an extra 21 st chromosome. This is a chance occurrence, although studies have shown that chances increase if the mother is older. Nature reviews genetics, 5 10 , 725-738.

Delayed development and behavioral problems are often reported in children with Down syndrome. In recent history, advances in medicine and science have enabled researchers to investigate the characteristics of people with Down syndrome.

I am specifically interested in the range of caused by Down's syndrome: The majority of children with Down syndrome function in the mild to moderate range of mental retardation. Research has indicated that individuals with mosaic Down syndrome may have fewer characteristics of Down syndrome than those with other types of Down syndrome.
