What is the phenotypic profile of Down syndrome (DS)?

Individuals with Down syndrome (DS) commonly possess unique neurocognitive and neurobehavioral profiles that emerge within specific developmental periods. These profiles are distinct relative to others with similar intellectual disability (ID) and reflect underlying neuroanatomic findings, providing support for a distinctive phenotypic profile.

What is the prognosis of Down syndrome (DS)?

Changes in emotional/behavioral functioning in adulthood are typically associated with neurodegeneration and individuals with DS are higher risk for dementia of the Alzheimer’s type. Individuals with DS possess many unique strengths and weaknesses that should be appreciated as they develop across the lifespan.

What is the difference between internalizing and externalizing behavior in Down syndrome?

In youth, externalizing behaviors may be problematic, whereas a shift toward internalizing behaviors emerges with maturity. Changes in emotional/behavioral functioning in adulthood are typically associated with neurodegeneration and individuals with DS are higher risk for dementia of the Alzheimer’s type.
