Vascular dementia; The misfolding of proteins is a common component of the proposed pathophysiology of many aging-related diseases. However, there is insufficient evidence to prove this. For example, the tau hypothesis for Alzheimer's proposes that tau protein accumulation results in the breakdown of neuron cytoskeletons, leading to Alzheimer's ...
First "The Methuselah-Strategy" then with Alzheimer-Lüge (English translation: "The Alzheimer's Lie") and Alzheimer ist heilbar (English translation: "Alzheimer's can be cured") two books about Alzheimer's disease, in which he presents his theory about the development of this special form of dementia from evolutionary history of life and ...
The brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. [6] The brain matter can be broadly classified as either grey matter, or white matter.
In Alzheimer’s disease, the most common form of dementia, the blood-brain barrier is disrupted. A new study has uncovered unique molecular signatures linked to the disruption of this blood-brain ...
Scientists have found a way to help Alzheimer’s drugs seep inside the brain faster — by temporarily breaching its protective shield. “Our goal is to give patients a head start,” by ...
The Nun Study of Aging and Alzheimer's Disease is a continuing longitudinal study, begun in 1986, to examine the onset of Alzheimer's disease. [1] [2] David Snowdon, an Epidemiologist and the founding Nun Study investigator, started the Nun Study at the University of Minnesota, later transferring the study to the University of Kentucky in 1990.

A normal brain on the left and a late-stage Alzheimer's brain on the right. During the final stage, known as the late-stage or severe stage, there is complete dependence on caregivers. [19] [33] [41] Language is reduced to simple phrases or even single words, eventually leading to complete loss of speech.
Abnormally low rates of cerebral glucose metabolism are found in a characteristic pattern in the Alzheimer's disease brain, particularly in the posterior cingulate, parietal, temporal, and prefrontal cortices. These brain regions are believed to control multiple aspects of memory and cognition. This metabolic pattern is reproducible and has ...
