Question

Quizplus · Accepted Answer

Down syndrome is a genetic disorder in which an individual has an extra copy of chromosome 21. Individuals with Down syndrome are at an increased risk for developing Alzheimer's disease, a progressive neurological disorder that affects cognitive and behavioral function. This risk is believed to be due to the presence of the amyloid precursor protein (APP) gene on chromosome 21, which plays a role in the development of Alzheimer's disease. Neurofibromatosis is a genetic disorder that can cause tumors to grow on nerves, but it is not typically associated with intellectual disabilities. Phenylketonuria (PKU) is a metabolic disorder that can cause intellectual disabilities if left untreated, but it is not linked to Alzheimer's disease. Hydrocephalus is a condition in which there is an accumulation of cerebrospinal fluid in the brain, which can cause intellectual disabilities in some cases, but it is not typically associated with Alzheimer's disease.
