Genetics Role in Alzheimers

In this article, it discusses Alzheimer's disease and how it is caused. Alzheimer's is a disease many people suffer from relatively old ages, usually over the age of 65. It is a degenerative disease of the brain, a gradual loss of memory, judgment, and ability to function come with being affected. Memory loss is said to be the number one sign of this disease. The loss of memory continuously becomes worse over time until it interferes with most aspects of daily living. Even in familiar settings,  a person may often become lost or confused. The normal routine tasks such as performing household chores become challenging without assistance. Some cases of early Alzheimers are caused by a gene mutation that can be passed from parents to their children. This is a result of early-onset familial Alzheimers disease. This disorder can result from a mutation within the APP, PSEN1 or PSEN2 genes. Those who inherit the APOE 4 allele have a higher chance of being affected by the disease. 




  1. This is a really interesting article! Studying diseases especially Alzheimers is really important since science is still trying to understand what causes it. Alzheimers specifically since it does not start until an older age is hard to predict, however if they are linking parts of the disease to a mutation in a gene it will be easier to track and recognize at earlier ages. I wonder how biotechnology could potentially help in the later years with a solution to Alzheimers? Awesome post!

  2. Alzheimer's is a very common and unique disease. This topic is very important to learn about due to the fact that we don't really know much about this disease. I hope one day we will be able to figure out a solution to this crazy disease. This post was very interesting.

  3. This is such an important topic in science and health to talk about. There is so much more to Alzheimer's that we do not know and I can't wait to see how technology will teach us in the future.
