Subtle changes in brain activity in the presence of both amyloid-beta and tau proteins may point to Alzheimer's disease, long before symptoms appear, a new study indicates.
Regarding incidence, cohort longitudinal studies (studies where a disease-free population is followed over the years) provide rates between 10 and 15 per thousand person-years for all dementias and 5–8 for AD, [235] [236] which means that half of new dementia cases each year are Alzheimer's disease. Advancing age is a primary risk factor for ...

Preliminary research indicates that iron deposits due to hemorrhaging, following traumatic brain injury (TBI), may increase tau pathology. While TBI does not routinely lead to accelerated NFT formation, further work may determine if other blood components or factors unrelated to hemorrhages are involved in this TBI-induced augmentation of tau ...
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 ...
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 ...
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.
