Watch Out for False Promises About So-Called Alzheimer's Cures

Unfortunately, when faced with a serious health issue, even the most rational person can be led to believe implausible claims.

AbstractAdult neurogenesis defects have been demonstrated in the brains of Alzheimer ’s disease (AD) patients. The neurogenesis impairment is an early critical event in the course of familiar AD (FAD) associated with neuronal loss. It was suggested that neurologic dysfunction in AD may be caused by impaired functioning of hippocampal neural stem cells (NSCs). Multiple metabolic an d structural abnormalities in neural mitochondria have long been suspected to play a critical role in AD pathophysiology. We hypothesize that the cause of such abnormalities could be defective elimination of damaged mitochondria. In the pre...

Conclusion: Aβ42 and tau seem to be worthy candidates for future salivary biomarkers for AD, but other biomarkers such as lactoferrin and selected metabolites also have potential. More studies must be carried out with larger sample sizes and a standardization of the sampling and processing method. Factors such as diurnal variation, AD patients' decreased ability of oral self-care, and salivary flowrates must be taken into consideration. PMID: 31191751 [PubMed - in process]

Authors: Wangchuk P, Sastraruji T, Taweechotipatr M, Keller PA, Pyne SG Abstract Corydalis plants containing isoquinoline alkaloids are reported to possess promising phamacological properties for the treatment of important diseases including cancer, inflammation, Alzheimer's disease and microbial infections. As part of a wider program investigating Bhutanese medicinal plants,.we have previously identified eight isoquinoline alkaloids from C. dubia. Out of these, we report here on two of the major alkaloids, scoulerine (1) and cheilanthifoline (2) and their inhibitory activities against acetylcholinesterase (anti-AC...

In this study, the activities of N-acetyl chitooligosaccharides (NA-COS), the hydrolytic products of chitin, were evaluated using Aβ-induced damages in animal and cell models of AD. Our results demonstrated that NA-COS significantly improved both acquisition (learning) and retention (memory) of AD rats on water maze task. HE staining of brain tissue sections showed that NA-COS could ameliorate hippocampal neurodegeneration induced by Aβ25-35. Further biochemical analysis showed that NA-COS treatment of intrahippocampal Aβ-microinjected rats was able to elevate choline acetyltransferase activity and attenuate...

Bouchard Taylor C. Davey Todd M. Doran Amyloid-β oligomers (AβOs) self-assemble into polymorphic species with diverse biological activities that are implicated causally to Alzheimer’s disease (AD). Synaptotoxicity of AβO species is dependent on their quaternary structure, however, low-abundance and environmental sensitivity of AβOs in vivo have impeded a thorough asses...

Conclusion: RD2 is the first anti-prion drug candidate. It is able to enhance cognition and impede neurodegeneration in three different transgenic AD mouse models, even under truly non-preventive conditions and even when applied orally. In addition, it is safe in humans.
