{description} What does Down Syndrome have in common with Alzheimer’s disease?  Down Syndrome is a common genetic disorder that causes delayed physical and cognitive development from birth. It affects over 350,000 people in the United States alone, and 1 out of every 1,000 live births.  Alzheimer’s is a neurological disorder that is associated with aging in otherwise normal individuals.  However, individuals with Down Syndrome develop Alzheimer’s by age 40, suggesting that the genes that contribute to Down Syndrome may be implicated in Alzheimer’s as well. {/description}
