Auguste Dieter, born in Kassel, Germany, was the first person to be diagnosed with Alzheimer's disease. She married Karl Dieter in 1880 and had only one daughter. Auguste lived a normal life until the late 1890s, but later began to show symptoms of dementia, such as memory loss, delusions, sleep problems, and screaming late at night. Her husband Karl was a railway worker, so he had to admit her to a mental institution in Frankfurt for the mentally ill and epileptic so that he could continue his work. On November 25, 1901, she was examined by Dr. Alois Alzheimer, who asked her several questions and repeated the same questions later to make sure she remembered her answers the first time. He also asked her to write her name, she tried to write it but couldn't and kept repeating the phrase "I am lost". After that, he put her in an isolation room for a period of time, and when he returned to her to take her out, she ran away and screamed, saying: "I did not hurt myself and I will not hurt myself." Her words guided them in the sanatorium to an important work, which is the condition she was suffering from and was called "Alzheimer's Stories". Several years later, she completely lost her mind and died on April 8, 1906. The dialogue below is the one that took place between Auguste Dieter and Dr. Alois Alzheimer as documented in the medical records and translated from the German language: "What is your husband's name?" She hesitated a long time before finally answering, saying: “I think it’s… Auguste.” “Ah… you visited us.” “Ah… I feel lost.” “Here and everywhere, here and now, you mustn’t think badly of me.” “We still live here.” After Mrs. Auguste had eaten her lunch, which was pork and spinach, although she was chewing on the pork, “What did you have for lunch now?” “First I had potatoes and radishes.” “Auguste,” she wrote, and as she wrote she kept repeating, “I think I’ve lost myself.” Thus, Dr. Alois Alzheimer concluded that she was unaware of time and place, could barely remember any details of her life, and gave answers that had nothing to do with the questions. Her mood also changed rapidly from anxiety to fear and mistrust. They did not allow her to walk around the sanatorium for fear that one of the residents would harm her. This was not the first time that Alzheimer's disease had destroyed the patient's psyche, but it had occurred in patients over the age of seventy. The curiosity to discover the disease was because the patient was young, only in her fifties. In the following weeks, he continued to interrogate her and record her answers. Most of the time, she would repeat, "Oh God, I think I've lost myself." It seems that she was aware that she was suffering from this disability. Dr. Alois Alzheimer named this disease "forgetfulness." In 1902, Dr. Alois Alzheimer left the sanatorium, but he kept in regular contact to check on her health. In 1906, he received a phone call informing him that Auguste Dieter had died. He asked them to send him all of her medical records and brain scans from the last years of her life. He noticed that her health had deteriorated significantly, and her death was the result of sepsis caused by the peeling of the infected skin. In a study of her brain scans, she was found to have neurofibrillary tangles, a sign of dementia.
