In the United States, as of 2012, 1 out of 8 senior citizens (13%) is suffering from alzheimer’s disease, making it the sixth most common cause of death. Alzheimer’s disease is a disease that is commonly characterized by a gradual decline of memory, language, and cognitive ability. It was first identified in 1907 by Alois Alzheimer, a German psychiatrist and neuropatologist, in  his case report describing the pathological structure of senile plaques and neurofibrillary tangles in the brain of a 55-year-old woman who showed severe dementia symptoms with pathological features, such as a reduction of total brain volume, thinning of the cortical grey matter, ventricular enlargement, and deposits of amyloid, tau, and cerebrovascular amyloid proteins.
