The Amyloid Cascade Hypothesis in Alzheimer’s Disease: It’s Time to Change Our Mind
Since its discovery in 1984, the beta amyloid peptide has treaded the boards of neurosciences as the star molecule in Alzheimer's disease pathogenesis. In the last decade, however, this vision has been challenged by evidence-based medicine showing the almost complete failure of clinical trials that experimented anti-amyloid therapies with great hopes. Moreover, data have accumulated which clear...
متن کاملMagnesium and Alzheimers Disease: The Cholinergic Hypothesis
The cholinergic deficit in Alzheimer’s disease (AD) remains the cornerstone for the understanding of chemical signal transfer. Hypofunctions of cholinergic systems are significantly involved in the signs and symptoms of senile dementia of the Alzheimer type. Cognitive deficits in AD have been widely associated with dysfunction of the cholinergic system. As a diagnostic marker of AD the activity...
متن کاملAlzheimer's Disease and the Amyloid Cascade Hypothesis: A Critical Review
Since 1992, the amyloid cascade hypothesis has played the prominent role in explaining the etiology and pathogenesis of Alzheimer's disease (AD). It proposes that the deposition of β-amyloid (Aβ) is the initial pathological event in AD leading to the formation of senile plaques (SPs) and then to neurofibrillary tangles (NFTs), neuronal cell death, and ultimately dementia. While there is substan...
متن کاملAlzheimer's disease: the amyloid cascade hypothesis: an update and reappraisal.
Here I recap the scientific and personal background of the delineation of the amyloid cascade hypothesis for Alzheimer's disease that I wrote with Gerry Higgins and the events leading to the writing of that influential review.
متن کاملAlzheimers Disease: A Novel Hypothesis for the Development and the Subsequent Role of Beta Amyloid
Spirochetes, biofilms, and innate immune system activity have all been recently found in the brains of Alzheimer’s disease patients. The mechanism and actions of those factors in producing the disease were discussed in those studies. However, neither the production nor the role of beta amyloid was included in the discussion of those studies. In this commentary, we hypothesize how the developmen...
