Discuss the hereditary and environmental factors that are implicated in the development of Alzheimer's disease.
What will be an ideal response?
Both heredity and environment can lead to the development of Alzheimer's. A mutated gene located on the extra chromosome 21 causes increased plaques and impaired both LTP and spatial learning. Three additional genes that were located affect amyloid production or its deposit in the brain. The APOE gene is associated with an increased risk by three- to eightfold, as well as with plaques and tangles. An additional 11 genes have been located and are involved in amyloid and tau pathways, inflammation, immune response, cell migration, and cellular functions. Environmental risks include exposure to pesticides, fertilizers, herbicides, and insecticides; airborne particulate matter; secondhand smoke; and electromagnetic fields. Health factors include vitamin D deficiency, sedentary lifestyle, diabetes, obesity, smoking, and hypertension. There is also a strong link between TBI and Alzheimer's-like brain pathology and dementia among combat soldiers, football players, and boxers. Bacterial infections has also been linked to a 5- to 10-fold increase in Alzheimer's disease.
