Collectively these changes may contribute to many of the neuropathological hallmarks of AD, as well as observed progressive deficiencies in cognitive function, while also linking elements of a number of the proposed hypotheses for the cause of AD. This review discusses the emergence of the RAS and its likely importance in AD, not only because of the multiple facets of its involvement, but also perhaps fortuitously because of the ready availability of numerous RAS-acting drugs, that could be repurposed as interventions in AD. acetylcholine, Alzheimers disease, amyloid-, angiotensin, cognitive decline, dementia, drug repurposing, epidemiology, hypertension, treatment, vascular INTRODUCTION As celebrates its 20th anniversary, this timeframe has also seen the emergence of research that points strongly to the involvement of the renin angiotensin system (RAS) as a likely, fortunately already modifiable, factor in the development and pathogenesis of Alzheimers disease (AD; MIM 104300 (https://www.omim.org/entry/104300)). While AD represents the most common form of dementia, with characteristic neuropathological hallmarks, it exists alongside a number of other causes of dementia, that have overlapping or related neuropathological processes and hallmarks. Yet, all the causes of the various dementias still share the same damning lack of restorative options, that are now vital to address the ongoing and escalating health care problems that dementia presents in an progressively aging populace [1]. A large proportion of people diagnosed with AD possess concurrent cerebrovascular disease (CVD) of variable severity, alongside the widely known characteristic AD-related amyloid- (A) pathologies like senile plaques and cerebral amyloid angiopathy (CAA), as well as tau-protein related neurofibrillary tangle pathology [2C4]. While AD shares many of the same risk factors for CVD and vascular cognitive impairment, the presence of vascular risk factors or CVD exacerbates the progression, or at least lowers the medical threshold for the manifestation, of AD [5, 6]. There seems to be a highly romantic and complex temporal relationship between the development of cardiovascular risk factors, CVD, and subsequent development and/or contribution toward the pathogenesis of AD. These may also contribute to age-associated cognitive decrease. Inlayed within this relationship look like mediators of RAS function that are characteristic in blood pressure rules and cardiovascular diseases like hypertension, but which more recently have been consistently noted to be involved in numerous pathological processes that are present in AD. This review provides an overview of the emergence of the RAS like a biochemical pathway that can have a chronic and integral part in the development and pathogenesis of AD. From initial suggestions of involvement in the pre-genome wide association studies (GWAS) era of genetic association studies in AD; through several consistently supportive and converging findings to numerous pre-clinical studies, the RAS offers rose to some prominence. The concurrent emergence of supportive study findings at a populace level have also helped to further elevate the RAS, like a mechanism that may clarify the widely approved, but not well recognized, association between mid-life hypertension and the development of cognitive impairment and/or dementia later on in existence. The convergence of genetic, molecular, and epidemiological evidence, and the fortunate availability of several medicines that work efficiently to inhibit RAS activity, has now brought forth the right now very reputable evidence that implicates RAS involvement in AD. Fortunately, this line of study can be and rapidly tested efficiently, using scientific studies of obtainable RAS performing medications currently, in mid-phase and early clinical studies for Advertisement.

Another characteristic that is common in AD, but not considered as part of the analysis, is the deposition of A in blood vessels in the brain known as CAA [4]. The presence of such features in the postmortem mind tissue, regarded as alongside a medical history that refers to progressive memory loss and cognitive impairment, all help to provide what currently remains as the only method to obtain a confirmatory analysis of AD. For decades, theories within the development of AD have been centered, in no small part, within the amyloid cascade hypothesis and the cholinergic hypothesis. These have both been extensively written about and updated in the intervening years. The amyloid cascade hypothesis [7] identifies the significant pathogenic contribution.
