Alzheimer’s disease (AD) is a neurodegenerative disorder that has affected millions of people worldwide. However, currently there is no treatment to cure the disease. The AD drugs available in the market only manage the disease symptomatically and the effects are usually short-term. Thus, there is a need to look at alternatives AD therapies. Mid-life hypertension has not only been recognised as a risk factor for AD, but its relation with AD has also been well established. Thus, antihypertensives are postulated to be beneficial in managing AD. This literature review aims to shed some light on the potential of repurposing antihypertensives to treat AD, considering recent updates. Four classes of antihypertensives, as well as their potential limitations and future prospects in being utilised as AD therapeutics are discussed in this review.

Background: Bulbous neuritic changes in neuritic plaques have already been described, and their possible effect on the clinical course of the disease has been discussed. OBJECTIVE: In our study, we focused on the location and density of these structures in patients with only Alzheimer’s disease (AD) and patients with AD in comorbidity with synucleinopathies. Methods: Utilizing immunohistochemistry and confocal microscopy, we evaluated differences of neocortical and archicortical neuritic plaques and the frequency of bulbous changes in the archicortex of 14 subjects with Alzheimer’s disease (AD), 10 subjects with the Lewy body variant of Alzheimer's disease (AD/DLB), and 4 subjects with Alzheimer's disease with amygdala Lewy bodies (AD/ALB). Also, the progression and density of neuritic changes over the time course of the disease were evaluated. Results: We found structural differences in bulbous dystrophic neurites more often in AD/DLB and AD/ALB than in pure AD cases. The bulbous neuritic changes were more prominent in the initial and progressive phases and were reduced in cases with a long clinical course. Conclusion: Our results indicate that there is a prominent difference in the shape and composition of neocortical and archicortical neuritic plaques and, moreover, that bulbous neuritic changes can be observed at a higher rate in AD/DLB and AD/ALB subjects compared to pure AD subjects. This observation probably reflects that these subacute changes are more easily seen in the faster clinical course of AD patients with comorbidities.

BACKGROUND The precise mechanisms whereby cardiovascular risk factors increase the risk of Alzheimer’s disease (AD) have not been delineated. We reported that microvessels isolated from AD brains overexpress a diverse array of neurotoxic and inflammatory proteins, which is consistent with the process of vascular activation. In pre-clinical studies using AD animal models we showed that a vascular activation inhibitor reduced vascular-derived neuroinflammation and improved cognitive performance. Thrombin is a key mediator of cerebrovascular activation in AD. OBJECTIVE This study aims to investigate the safety and potential efficacy of the direct thrombin inhibitor dabigatran, in patients with mild cognitive impairment (MCI) or mild AD to decrease vascular-derived neuroinflammation and improve cognitive performance. METHODS Participants will be enrolled then evaluated quarterly throughout the 24-month study. This is a 24-month randomized-control, double-blind, placebo-controlled, multicenter, delayed-start, pilot study evaluating thrombin inhibition in people with biomarker-confirmed MCI probably due to AD or mild AD. 40 - 60 participants will be recruited between 50 - 85 years old. In the initial 9-months of study, either dabigatran or placebo will be orally administered to patients at a dose of 150 mg per day. After 9 months of the placebo-control (Phase I), the placebo arm will cross-over to an active, open-label (Phase II) where all patients will be treated with a 150 mg daily dose of dabigatran orally for an additional 12 months. A 3-month non-treatment follow-up period will assess duration of effects. RESULTS Beginning in July 2019, and concluding in August 2022, this study is expected to publish final results in January 2023. CONCLUSIONS BEACON is a first-in-kind randomized clinical trial targeting thrombin activation in AD therapeutics. This trial will stimulate translational investigations of an FDA-approved drugs in a newly defined therapeutic areas. CLINICALTRIAL Clinicaltrials.gov NCT03752294

Background: Utilities of blood-based biomarkers in Alzheimer’s disease (AD) clinical trials remain unknown. Objective: To evaluate the ability of plasma neurofilament light chain (NfL) to predict future declines in cognition and activities of daily living (ADL) outcomes in 26 older adults with mild-to-moderate AD dementia from the FIT-AD Trial. Methods: Plasma NfL was measured at baseline and 3 and 6 months. Cognition and ADL were assessed using the AD Assessment Scale-Cognition (ADAS-Cog) and AD Uniform Dataset Instruments and Disability Assessment for Dementia (DAD), respectively, at baseline, 3, 6, 9, and 12 months. Linear mixed effects models were used to examine the associations between baseline or change in plasma NfL and changes in outcomes. Results: Higher baseline plasma NfL was associated with greater rate of decline in ADAS-Cog from baseline to 6 months (standardized estimate of 0.00462, p = 0.02853) and in ADL from baseline to 12 months (standardized estimate of –0.00284, p = 0.03338). Greater increase in plasma NfL in short term from baseline to 3 months was associated with greater rate of decline in memory and ADL from 3 to 6 months (standardized estimate of –0.04638 [0.003], p = 0.01635; standardized estimate of –0.03818, p = 0.0435) and greater rate of decline in ADL from 3 to 12 month (standardized estimate of –0.01492, p = 0.01082). Conclusion: This study demonstrated that plasma NfL might have the potential to predict cognitive and function decline up to 12 months. However, future studies with bigger sample sizes need to confirm the findings.
