The Link Between Down Syndrome and Alzheimer's Disease

Relationship between Down's Syndrome and Alzheimer's Disease The Education Law of Persons with Disabilities stipulates that "All disabled children including mental retardation should receive education of disabled students as much as possible" (2) . In an ideal world, society will not have any problems even if complying with this law, but the world is not perfect.

Many people with Down's syndrome develop Alzheimer's disease. The symptoms and signs of Alzheimer's disease often appear 10 to 20 years earlier than people with Down's syndrome. Genes contained in extra chromosomes that cause Down's syndrome markedly increase the risk of Alzheimer's disease. These risk factors are also associated with vascular dementia, which is a type of dementia caused by damaged blood vessels in the brain. Cooperating with your medical team to plan to manage these factors will help protect your heart - and may also help reduce the risk of Alzheimer's disease and vascular dementia Hmm

Alzheimer's disease is a neurodegenerative disease found in patients with Down's syndrome. The illness was named after the 1906 neuropathologist Alois Alzheimer's disease. Patients with Down's syndrome experience neuropathology like Alzheimer's disease in their 40s. Initially, Alzheimer's disease affects certain parts of the brain, such as memory and language. But after a while, the disease progresses and causes problems in every aspect of our lives. Alzheimer's disease has two forms, familial and sporadic. Familial Alzheimer's disease is a heritable rare illness. Alzheimer's disease has three main types of lesions. This is subsequently caused by mutations in several genes, such as APP, which will result in overproduction of amyloid beta protein. The most common form of Alzheimer's disease is a sporadic form that causes 90% of cases of Alzheimer's disease

Down syndrome is associated with an increased risk of many chronic diseases often associated with the elderly, such as Alzheimer's disease. Accelerated aging suggests that trisomy 21 increases the biological age of the tissue, but the molecular evidence of this hypothesis is sparse. According to a tissue age biomarker called epigenetic clock, 21 trisomy increased the age of blood and brain tissue (average 6.6 years). If screening tests predict high risk of Down syndrome, more invasive diagnostic tests (amniocentesis or chorionic villus sampling) are required to confirm diagnosis. If Down syndrome occurred in one of 500 pregnancies and the test result was 5%, only one of the 26 females diagnosed as positive had Down's syndrome. If the false positive rate of the screening test is 2%, this means that one out of 11 positive screening patients has a fetal DS
