Alzheimer’s disease
How does Alzheimer’s disease develop and what are its symptoms? Alzheimer disease is the most common form of Dementia, a lethal brain disorder that impacts daily living throughmemory loss and cognitive changes. Alzheimer’s is a degenerative disease, progressing from mild forgetfulness to widespread neurological impairment and ultimately death. Chemical and structuralchanges in the brain gradually destroy the ability to create, remember, learn, reason, and relate to others.  While critical cells die, a dramatic personality change occurs and body systems fail. It mostlyhappens at an elder age. Victims can’t remember the most simple things in their daily routine. Like where they left their glasses.  They go grocery shopping, and left the list at home.  They have atendency of forgetting the name s of those around them, etc. What are the changes seen in Alzheimer disease? The changes that are being seen in Alzheimer are the tendency of forgetting things, and theability to remember, create and relate to others. The medical science hopes one day to find the cure, so this neurological disease stops affecting the elder population. Alzheimer’s disease is found tooccur in two forms: Early-onset and Late-onset.
Early-onset Alzheimer’s disease is the most uncommon form of the disease, it happens to less than ten percent of all Alzheimer’s patients. Patientson the Early-onset Alzheimer’s disease are normally diagnosed before the age of 65. If this is diagnosed at a younger age, the patient s usually have some kind of brain abnormalities that triggers thedisease. The cause is largely genetic, with chromosome 14 being the root of the problem. Myoclonus is one of the symptoms of this stage of the disease; it normally is the result of the mutation ofthree genes – presenilin 1, presenilin 2 and amyloid precursor protein. Research has shown that they are of no danger at all when separate but are the sources of the disease unlike when together...
