Dr. Aloysius "Alois" Alzheimer (German 14 June 1864 – 19 December 1915) was a Bavarian-born 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.
Alois Alzheimer was born in Marktbreit, Bavaria on 14 June 1864. Alzheimer attended Aschaffenburg, Tübingen, Berlin, and Würzburg universities. He received a medical degree at Würzburg University in 1886. In the following year, he spent five months assisting mentally ill women, before he took an office in the city mental asylum in Frankfurt am Main: the Städtische Anstalt für Irre und Epileptische (Asylum for Lunatics and Epileptics). Emil Sioli (1852–1922) was the dean of the asylum.
Another neurologist, Franz Nissl (1860–1919), began to work in the same asylum with Alzheimer, and they knew each other. Much of Alzheimer's later work on brain pathology made use of Nissl's method of silver staining of the histological sections. Alzheimer was the co-founder and co-publisher of the journal Zeitschrift für die gesamte Neurologie und Psychiatrie, though he never wrote a book that he could call his own.
In 1901, Dr. Alzheimer observed a patient at the Frankfurt Asylum named Auguste Deter. The 51-year-old patient had strange behavioral symptoms, including a loss of short-term memory. This patient would become his obsession over the coming years. In April 1906, Mrs Deter died and Alzheimer had the patient records and the brain brought to Munich where he was working at Kraepelin's lab. With two Italian physicians, he used the staining techniques to identify amyloid plaques and neurofibrillary tangles.
A speech given on 3 November 1906 was the first time the pathology and the clinical symptoms of presenile dementia were presented together. Through extremely fortunate circumstances the original microscope preparations on which Alzheimer based his description of the disease were rediscovered some years ago in Munich and his findings could thus be reevaluated.
Since German was the lingua franca of science (and especially of psychiatry) at that time, Kraepelin's use of Alzheimer's disease in a textbook made the name famous. By 1911, his description of the disease was being used by European physicians to diagnose patients in the US.
In August 1912, Dr. Alzheimer fell ill on the train on his way to the University of Breslau, where he had been appointed professor of psychiatry in July 1912. Most probably he had a streptococcal infection and subsequent rheumatic fever leading to valvular heart disease, heart failure and kidney failure. He never recovered completely from this illness. He died of heart failure on 19 December 1915, at the age of 51 in Breslau, Silesia, presently Wrocław, Poland. He was buried on 23 December 1915 next to his wife Cecilie in the Hauptfriedhof in Frankfurt am Main.
Alzheimer's disease (AD), also known as Alzheimer disease, or just Alzheimer's, accounts for 60% to 70% of cases of dementia. It is a chronic neurodegenerative disease that usually starts slowly and gets worse over time. The most common early symptom is difficulty in remembering recent events (short term memory loss). As the disease advances, symptoms can include: problems with language, easily getting lost, mood swings, loss of motivation, not managing self care, and behavioural issues. As a person's condition declines they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. Although the speed of progression can vary, the average life expectancy following diagnosis is three to nine years.
