Recently, a link between cholinergic neuronal activity and the activity of alpha-secretase has been highlighted, [19] which can discourage amyloid-beta proteins deposition in brain of patients with Alzheimer's disease. Alzheimer's disease has been identified as a protein misfolding disease, or proteopathy, due to the accumulation of abnormally ...
Alzheimer's disease is associated with sleep disorders but the precise relationship is unclear. [176] [177] It was once thought that as people get older, the risk of developing sleep disorders and AD independently increase, but research suggests sleep disorders may be a risk factor for AD. [178]
This article will cover the epigenetics and treatment of Alzheimer's disease (AD), Huntington's disease (HD), and Parkinson's disease (PD). These diseases are characterized by chronic and progressive neuronal dysfunction, sometimes leading to behavioral abnormalities (as with PD), and, ultimately, neuronal death, resulting in dementia.
For the first time, researchers have identified a genetic form of late-in-life Alzheimer’s disease — in people who inherit two copies of a worrisome gene. Scientists have long known a gene ...
Neurofibrillary tangles (NFTs) are intracellular aggregates of hyperphosphorylated tau protein that are most commonly known as a primary biomarker of Alzheimer's disease. Their presence is also found in numerous other diseases known as tauopathies. Little is known about their exact relationship to the different pathologies.
Alternatively, diseases exhibiting tau pathologies attributed to different and varied underlying causes are termed 'secondary tauopathies'. Some neuropathologic phenotypes involving tau protein are Alzheimer's disease, frontotemporal dementia, progressive supranuclear palsy, and corticobasal degeneration. [1]
