Title: Alzheimer's disease
Content:  The ancient Greek and Roman philosophers and physicians associated old age with increasing dementia. It was not until 1901 that German psychiatrist Alois Alzheimer identified the first case of what became known as Alzheimer's disease, named after him, in a fifty-year-old woman he called Auguste D. He followed her case until she died in 1906 when he first reported publicly on it. During the next five years, eleven similar cases were reported in the medical literature, some of them already using the term Alzheimer's disease. The disease was first described as a distinctive disease by Emil Kraepelin after suppressing some of the clinical (delusions and hallucinations) and pathological features (arteriosclerotic changes) contained in the original report of Auguste D. He included Alzheimer's disease, also named presenile dementia by Kraepelin, as a subtype 
Title: November 1901
Content: Dr. Alois Alzheimer, a German psychiatrist at the Hospital for the Mentally Ill and Epileptics in Frankfurt, had his first meeting with the patient who would become the first person to be diagnosed with Alzheimer's disease. Auguste Deter, the 51-year-old wife of an office clerk, had been admitted to the hospital the day before, after having gradually deteriorated over eight months that had started with delusions and memory loss in March. After her death on April 8, 1906, Alzheimer would examine samples of her brain taken at autopsy, and publish his findings about "Auguste D." in a paper titled On a Peculiar, Severe Disease Process of the Cerebral Cortex. ; Twenty-seven employees of the Penberthy Injector Company in Detroit were killed by the explosion of a boiler. The blast, which happened at the company's factory at Abbott Street 
Title: Alois Alzheimer
Content:  Alois Alzheimer (14 June 1864 – 19 December 1915) was a German psychiatrist and neuropathologist and a colleague of Emil Kraepelin. Alzheimer is credited with identifying the first published case of "presenile dementia", which Kraepelin would later identify as Alzheimer's disease.
Title: Florbetapir (18F)
Content:  Since the disease was first described by Alois Alzheimer in 1906, the only certain way to determine if a person indeed had the disease was to perform a biopsy on the patient's brain to find distinctive spots on the brain that show the buildup of amyloid plaque. Doctors must diagnose the disease in patients with memory loss and dementia based on symptoms, and as many as 20% of patients diagnosed with the disease are found after examination of the brain following death not to have had the condition. Other diagnostic tools, such as analysis of cerebrospinal fluid, magnetic resonance imaging scans looking for brain shrinkage and PET scans looking at how glucose was used in the brain,

Content:  senile dementia in the eighth edition of his Textbook of Psychiatry, published on 15 July, 1910. For most of the 20th century, the diagnosis of Alzheimer's disease was reserved for individuals between the ages of 45 and 65 who developed symptoms of dementia. The terminology changed after 1977 when a conference on Alzheimer's disease concluded that the clinical and pathological manifestations of presenile and senile dementia were almost identical, although the authors also added that this did not rule out the possibility that they had different causes. This eventually led to the diagnosis of Alzheimer's disease independent of age. The term senile dementia of the Alzheimer type (SDAT) was used for a time to describe the condition in those over 65, with classical Alzheimer's disease being used to describe those who 
Title: Early-onset Alzheimer's disease
Content:  The symptoms of Alzheimer's disease as a distinct nosologic entity were first identified by Emil Kraepelin, who worked in Alzheimer's laboratory, and the characteristic neuropathology was first observed by Alois Alzheimer in 1906. Because of the overwhelming importance Kraepelin attached to finding the neuropathological basis of psychiatric disorders, Kraepelin made the decision that the disease would bear Alzheimer's name.

Title: Alois Alzheimer
Content:  Alzheimer discussed his findings on the brain pathology and symptoms of presenile dementia publicly on 3November 1906, at the Tübingen meeting of the Southwest German Psychiatrists. The attendees at this lecture seemed uninterested in what he had to say. The lecturer that followed Alzheimer was to speak on the topic of "compulsive masturbation", which the audience of 88 individuals was so eagerly awaiting that they sent Alzheimer away without any questions or comments on his discovery of the pathology of a type of senile dementia. Following the lecture, Alzheimer published a short paper summarizing his lecture; in 1907 he wrote a larger paper detailing the disease and his findings. The disease would not become known as Alzheimer's disease until 1910, when Kraepelin named it so in the chapter on "Presenile and Senile Dementia" in the 8th edition of his Handbook of Psychiatry. By 1911, his description of the disease was being used by European physicians to diagnose patients in the US.

Content:  vessels of the cerebral cortex. In 1907, Bavarian psychiatrist Alois Alzheimer was the first to identify and describe the characteristics of progressive dementia in the brain of 51-year-old Auguste Deter. Deter had begun to behave uncharacteristically, including accusing her husband of adultery, neglecting household chores, exhibiting difficulties writing and engaging in conversations, heightened insomnia, and loss of directional sense. At one point, Deter was reported to have "dragged a bed sheet outside, wandered around wildly, and cried for hours at midnight." Alzheimer began treating Deter when she entered a Frankfurt mental hospital on November 25, 1901. During her ongoing treatment, Deter
