Did you know? Symptomatic Alzheimer's disease before age 40 is not common in people with Down syndrome. 

Alzheimer's disease is more common in people with Down syndrome; however, symptomatic Alzheimer's disease before age 40 is not common in people with Down syndrome. The authors of the Global Medical Care Guidelines for Adults with Down Syndrome write, "Caution is needed when diagnosing age-related, Alzheimer's-type dementia in adults with Down syndrome younger than age 40 due to its low prevalence before this age." Our Resource Library has a section (linked here) with more information on Alzheimer's disease in people with Down syndrome.
