In 2050, an estimated 50 million Americans over the age of 65 are expected to have Alzheimer 's Disease. Alzheimer 's Disease has been acknowledged and portrayed throughout history. Throughout this report the history, symptoms, different methods of diagnosis, prognosis or outcome, and treatments options for Alzheimer 's Disease will be discussed. In 1906, Dr. Alois Alzheimer, a German physician, identified a collection of abnormal brain cells after a patient died after suffering years of memory problems, confusion, and difficulty understanding questions. After the death of the patient, Dr. Alzheimer noticed neuritic plaques, which are dense deposits around nerve cells. Within the neuritic plaque he observed neurofibrillary tangles. Since Dr. Alzheimer 's discovery more than one hundred years ago there have been many new discoveries regarding Alzheimer 's Disease. A link between Cognitive decline and the number of tangles and plaques in the brain were discovered in the 1960s and it was determined that Alzheimer 's disease was not a regular part of aging. Over the past 30 years there has been a lot more attention and research done on the effects of Alzheimer 's Disease. “Over the last decade, scientists have substantially progressed in understanding potential environmental, genetic and other risk factors for Alzheimer 's Disease, the processes leading to formation of plaques and tangles in the brain, and the brain regions that are affected. Specific genes related to…
