Alzheimer’s is a type of dementia that causes problems with memory, thinking and behaviour. It is a degenerative brain disorder which affects the elderly people and leads to significant disability. Heart diseases called cardiovascular diseases which are very common diseases start affecting people at much younger age. There is an interesting genetic connection that has been described between Alzheimer’s disease and heat diseases, the apolipoprotein E gene, also known as ApoE. Genetic testing for ApoE which is done mainly in research settings and isn’t yet widely available cannot predict whether a person will develop Alzheimer’s disease, only whether they may be more likely than others to do so. Alzheimer’s disease and heat diseases, people who have a variant of appolyco protein what is called appo E4 are supposed to have a fourfold higher risk of developing Alzheimer’s disease as well as are at risk of developing heart diseases. Because of this genetically link people who have Alzheimer’s are higher risk of developing heart diseases. Even people with independent of Alzheimer’s disease often have the risk of developing hypertension and are at risk of stroke. People can also develop vascular dementia because of repeated strokes.
