Many individuals with Down syndrome who live past the age of 35, develop the characteristic markers for Alzheimer’s disease. The markers are plaques and/or tangles in the brain. Not all individuals who have these markers develop symptoms of Alzheimer’s disease. Studies indicate that the prevalence of the disease in individuals with Down syndrome increases with age, as it does with the general population.
