The protein I had was Presenilin 2, which is located on the PSEN2 gene, which is on Chromosome 1. Presenilin 2 is involved with Alzheimer’s disease.
Alzheimer’s is a disease that kills brain cells. It is detrimental to the mental functions of humans and can even lead to death. As time passes, the disease grows worse. Forgetfulness is a symptom of Alzheimer’s Disease. The amount of memory loss will worsen over time. Victims of Alzheimer’s Disease may forget things they have known for a while and eventually, may even forget people. Another symptom is that a person who once made good choices may have trouble making proper judgements.
Alzheimer’s deals with the brain, making it harder to process the world around you. Having trouble multitasking is also another symptom of Alzheimer’s Disease. One effect of Alzheimer’s Disease is the shrinking of brain tissue.
Another effect is changes in the personality of the effected person. They may have mood swings and other uncharacteristic actions.The protein Presenilin 2 relates to Alzheimer’s Disease because mutations of Presenilin 2 lead to an increase in production of amyloid-beta. Presenilin 2 normally processes amyloid precursor protein, however, mutations disrupt this. This disruption helps lead to increased production of amyloid beta peptide. The amyloid-beta mentioned above then makes up clumps that are found in Alzheimer victims brains.
A correlation between the amyloid-beta and brain cell death is possible. This disease can be fatal, and there is no cure. However, there are certain treatments that can help, although they don’t eliminate the problem.
Treatment includes medication. Memantine(Namenda) can help slow the progression of symptoms. Along with this, treatment also includes Cholinesterase inhibitors. These are drugs that provide a nuero transmitter. Exercise and a safe environment are also ways to alleviate the severity of Alzheimer’s Disease.
