Alzheimer’s disease was originally named Dr. Aloysius “Alois” Alzheimer’s, which was a German doctor who specializes in psychiatry and neuropathology. The term “Alzheimer’s disease” was coined in a book written by Dr. Emil Kraepelin, German psychiatrist accomplished and said mentor of Dr. Alzheimer.Dr. Alzheimer was born in Markbreit am Main Germany on June 14, 1864, and became a doctor after obtaining his Bachelor’s degree from the University of Würzburg. The case which led to the nomenclature for the disease that we now know as Alzheimer’s disease began with a woman named Frau Auguste D, a patient of 51-year-old who was admitted to the Municipal Mental asylum, the hospital where Dr. Alzheimer’s was a doctor. The patient exhibits symptoms behavioural and cognitive deterioration as the loss of short-term memory, auditory hallucinations, paranoia, and aggression. Dr. Alzheimer began to study the patient. At the time of the death of the patient in 1906, Dr. Alzheimer had begun to work in the laboratory of Anatomy of the real psychiatric clinic at a University of Munich, where he worked with Dr. Emil Kraepelin. After his death, brain of the patient and the records were sent to the clinic for the research. While Dr. Alzheimer observations were not classified as new discoveries in the medical field, he identified in brains of women characteristics associated with patients suffering from severe dementia. Dr. Alzheimer identified features such as a cerebral cortex thinning, peculiar matas had now called amyloid plaques and morays of fibers that came to be known as neurofibrillary tangles. Previously had observed these changes in the brain, and a common speculation is that Dr. Alzheimer not made an attempt to clear of classifying their findings as a new disease. However, it is believed a speech about their findings reported in 1906 by many to be the first collective presentation link symptoms of presenile dementia with the physical changes that had taken place in the brain of a patient.Not, however, in the manual of Psychiatry (eighth edition), Dr. Kraepelin commented on the results of the autopsy and includes use of the phrase “Alzheimer’s disease” in its description. In 1911, Dr. Alzheimer used the new term in a document. Although today, many argue that it was not responsible for the discovery of the disease Dr. Alzheimer, the term “Alzheimer’s disease” captured en. In a few years, the name of Alzheimer’s disease was well known and began to be used by doctors for the diagnosis. Other features that help doctors identify probable cases of Alzheimer’s disease, although there is no definitive means of diagnosis of the disease until after death have been discovered since then.
