Treatment of Alzheimer disease in Down syndrome
Down syndrome (DS) is the most common genetically driven intellectual disability. Neuro pathological evidence of an associa‐ tion between Alzheimer disease (AD) and DS was published 11 years before trisomy 21 was described as the cause of DS.1 AD‐type pathology is almost universal in patients with DS in their 40s, although the develop ment of clinically detectable cognitive decline typically la...
متن کاملCerebrovascular pathology in Down syndrome and Alzheimer disease
People with Down syndrome (DS) are at high risk for developing Alzheimer disease (AD) with age. Typically, by age 40 years, most people with DS have sufficient neuropathology for an AD diagnosis. Interestingly, atherosclerosis and hypertension are atypical in DS with age, suggesting the lack of these vascular risk factors may be associated with reduced cerebrovascular pathology. However, becaus...
متن کاملDissecting Alzheimer disease in Down syndrome using mouse models
Down syndrome (DS) is a common genetic condition caused by the presence of three copies of chromosome 21 (trisomy 21). This greatly increases the risk of Alzheimer disease (AD), but although virtually all people with DS have AD neuropathology by 40 years of age, not all develop dementia. To dissect the genetic contribution of trisomy 21 to DS phenotypes including those relevant to AD, a range o...
متن کاملAmyloid plaque core protein in Alzheimer disease and Down syndrome.
We have purified and characterized the cerebral amyloid protein that forms the plaque core in Alzheimer disease and in aged individuals with Down syndrome. The protein consists of multimeric aggregates of a polypeptide of about 40 residues (4 kDa). The amino acid composition, molecular mass, and NH2-terminal sequence of this amyloid protein are almost identical to those described for the amyloi...
متن کاملBrain interleukin 1 and S-100 immunoreactivity are elevated in Down syndrome and Alzheimer disease.
Interleukin 1, an immune response-generated cytokine that stimulates astrocyte proliferation and reactivity (astrogliosis), was present in up to 30 times as many glial cells in tissue sections of brain from patients with Down syndrome and Alzheimer disease compared with age-matched control subjects. Most interleukin 1-immunoreactive glia in Down syndrome and Alzheimer disease were classified as...
