It is common for people to have mixed dementia — a combination of two or more types of dementia. Alois Alzheimer. In , Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness. Her symptoms included memory loss, language problems, and unpredictable behavior.
After she died, he examined her brain and found many abnormal clumps now called amyloid plaques and tangled bundles of fibers now called neurofibrillary, or tau, tangles. Another feature is the loss of connections between neurons in the brain.
Neurons transmit messages between different parts of the brain, and from the brain to muscles and organs in the body. Changes in the brain may begin a decade or more before symptoms appear. Previously healthy neurons stop functioning, lose connections with other neurons, and die.
The damage initially appears to take place in the hippocampus and the entorhinal cortex, which are parts of the brain that are essential in forming memories. As more neurons die, additional parts of the brain are affected and begin to shrink.
Some people with memory problems have a condition called mild cognitive impairment MCI. With MCI, people have more memory problems than normal for their age, but their symptoms do not interfere with their everyday lives. Movement difficulties and problems with the sense of smell have also been linked to MCI. Some may even revert to normal cognition. To overcome the grief of his wife's death, Alzheimer worked more intensively at the hospital than ever before.
He saw all newly admitted patients and made a detailed and extensive documentation of his findings. On November 26, , he investigated the newly admitted female patient Auguste D. Apart from his very intensive clinical work, Alzheimer - together with Sioli - organized the establishment of a special branch hospital for mental patients close to Frankfurt in the Taunus mountains.
In addition, he began to write a so-called Habilitationssdirift postdoctoral thesis for a university lecturing qualification as a basis for an application at a medical faculty of a German university.
The relationship between syphilis and general paresis was still controversial: Treponema pallidum, [Spirochaela pallida] had not yet been discovered and no effective treatment was available. In the summer of , little more than one year after the death of Alzheimer's wife, Emil Kraepelin invited him to join the Heidelberg research team as assistant to the Heidelberg Hospital.
This was a great honor because Kraepelin was at the time one of the most, prominent and influential psychiatrists in Germany. In addition, Alzheimer's great friend Nissl had then been working in the Heidelberg Hospital for 7 years.
In spite of many reasons in favor of Heidelberg, Alzheimer refused Kraepelin's invitation and applied - unsuccessfully - for the leading position in a Hessian state hospital. When Nissl heard about, this, he persuaded Kraepelin to repeat his offer of a position at the Heidelberg Hospital to Alzheimer. Kraepelin did so and Alzheimer accepted; he moved to Heidelberg at the end of Sioli and the Frankfurt, authorities explicitly regretted the departure of Alzheimer.
However, Sioli approved of Alzheimer's decision, since it led to a university position the University of Frankfurt was only established in Sioli promised Alzheimer that he would tell him of the fate of all the patients who had been of special interest to Alzheimer from a scientific point of view. Thus, some years later, Alzheimer obtained information on the course of Auguste D.
Alzheimer moved to Heidelberg expecting to work there for a long time. Bumm , died at the age of For some years, Bumm had been responsible for the planning and construction of a new modern, large university hospital for psychiatry. At the time of Bumm's unexpected death, the building was not yet finished and the Munich chair suddenly became vacant. On the recommendation of the Faculty of Medicine, the chair and directorship were offered to Kraepelin. After only momentary hesitation, Kraepelin agreed to soon take up the position and moved in autumn He was accompanied by three coworkers from his Heidelberg team, one of whom was Alzheimer.
Kraepelin used the remaining year till the official opening of the hospital in November to work on his textbooks and undertook a long voyage to explore Indonesia. During this time, Alzheimer's task in Munich was the supervision of the completion of the building and the organization of hospital equipment. After his return, Kraepelin stated that. Alzheimer had done an excellent job.
After the opening of the hospital in November , R. Gaupp Figure 3 was appointed senior assistant and Alzheimer became Kraepelin's first, research assistant. In this position, Alzheimer received no payment, but he could devote all his time to research. Alzheimer's remarkable private fortune enabled him to work under these peculiar conditions. Alzheimer was head of the histopathological laboratory until During these 8 years, numerous young scientists from many countries were trained by Alzheimer and later became famous neuropathologists or clinical psychiatrists.
The list, of Alzheimer's coworkers Figure 4 includes many prominent names - N. Achucarro, I. Bonfiglio, L. Casamaior, U. Cerletti, H-G Crcutzfeld, C. Econome, A. Jakob, K. Kleist, F. Lewy, L. Merzbacher, G. Perusini, and W. Spielmeyer - a who's who of contemporary neuropathology! In October , a short time after moving to Munich, Alzheimer arranged for his children to follow him and they all lived in a large house near the hospital, together with his sister as housekeeper.
Furthermore, at the end of , he bought, a big weekend house beside a small lake near Munich. An important step in Alzheimer's academic career came in November when he presented his Habilitationsschrift in Munich. After the Munich Hospital had opened November 11, , Alzheimer hoped to again have more time for his research.
This happened only for a short time, but with great effect. In April , Sioli, with whom Alzheimer worked in. Frankfurt, informed him of the death of the patient Auguste D. By this means, epoch-making research was enabled. Alzheimer discovered and described the histological alterations later known as plaques and neurofibrillary tangles.
Kraepelin encouraged Alzheimer to present the case of Auguste D. To change or withdraw your consent choices for VerywellHealth.
