Alzheimer disease (AD) is a chronic neuro-degenerative disease accounting for almost 70% of dementia cases. The most common symptom being short term memory loss, the disease leads to a decline in self management and behavior with impacts varying per individual. Though, AD is an age related disorder with people above 60 being most likely to be affected, individuals with a history of frequent head injuries, depression, hypertension may also carry a risk. Researchers and scientists are unsure about the cause of Alzheimers but studies have been conducted and they claim that 7 out of 10 cases are genetically caused (e4 allele of gene apolipoprotein E). Additionally, pathophysiological causes (Plaques and neurofibrillary tangles, neuronal death) cannot be ruled out in the disease pathology and progression. AD forms one of the most actively explored and researched areas in the field of medicine.
