And following a heart attack, up to 50% of people experience some loss of brain function. Like the other heart conditions already mentioned, CHD is linked to brain harm through reduced blood flow ...
“Given the significant risk of Alzheimer’s disease and cardiovascular diseases — including coronary artery disease traits — globally, we were motivated to investigate potential genetic ...
A 2023 study published in the journal Acta Neuropathologica examined tissue from the brain and retina of 86 individuals and compared samples from donors with normal cognitive function to samples ...
Meta-analysis of many reported studies suggests that SPECT with this tracer is about 74% sensitive at diagnosing Alzheimer's disease vs. 81% sensitivity for clinical exam (cognitive testing, etc.). More recent studies have shown the accuracy of SPECT in Alzheimer's diagnosis may be as high as 88%. [4]
Vascular dementia can sometimes be triggered by cerebral amyloid angiopathy, which involves accumulation of amyloid beta plaques in the walls of the cerebral arteries, leading to breakdown and rupture of the vessels. [2] [5] Since amyloid plaques are a characteristic feature of Alzheimer's disease, vascular dementia may occur as a consequence ...
Alzheimer's disease is believed to occur when abnormal amounts of amyloid beta (Aβ), accumulating extracellularly as amyloid plaques and tau proteins, or intracellularly as neurofibrillary tangles, form in the brain, affecting neuronal functioning and connectivity, resulting in a progressive loss of brain function.
