Newest firstBackground Older adults, particularly those residing in long-term care, experience disproportionate rates of cognitive decline and Alzheimer's disease (AD). While isolated nutrient supplementation has demonstrated limited clinical efficacy, comprehensive whole-food dietary patterns may offer significant neuroprotective benefits through complex nutrient synergy. This systematic review evaluates the efficacy of the…
Open article record in new tab ↗Synaptic dysfunction is the earliest and most critical pathological feature of Alzheimer's disease (AD), directly contributing to cognitive decline. This review provides an integrative overview of the molecular and biochemical modulators governing synaptic plasticity and their disruption in AD. We discuss how the collective impairment of Aβ aggregation, tau pathology, calcium imbalance, oxidative stress, and neuro…
Open article record in new tab ↗Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, memory impairment, and behavioral disturbances. While its pathogenesis is complex, increasing evidence supports the role of an imbalance between excitatory and inhibitory (E/I) neuronal activity in disease progression. E/I imbalance contributes to synaptic impairment, network hypersynchrony, and ultimately cogn…
Alzheimer's disease (AD) is a major neurodegenerative disorder that causes severe cognitive decline and poses a significant burden on global health systems. Despite extensive research, effective treatments to stop neurodegeneration or promote neuronal regeneration in AD remain elusive. Psychoactive substances as modulators of neurophysiological functions, have received increased attention in research. The main psy…
Extra-cerebral manifestations of Alzheimer's disease (AD) develop in the retina, which is, therefore, considered a "window to the brain". Recent studies demonstrated the dysregulation of the endocannabinoid (eCB) system (ECS) in AD brain. Here, we explored the possible alterations of ECS and the onset of gliosis in the retina of AD-like mice. Tg2576 (TG) mice overexpressing the amyloid precursor protein (APP) were…
Cannabidiolic (CBDA) and cannabigerolic (CBGA) acids are naturally occurring compounds from Cannabis sativa plant, previously identified by us as dual PPARα/γ agonists. Since the development of multitarget-directed ligands (MTDL) represents a valuable strategy to alleviate and slow down the progression of multifactorial diseases, we evaluated the potential ability of CBDA and CBGA to also inhibit enzymes involved…
The endocannabinoid N-arachidonoylethanolamine (AEA) is a pro-homeostatic bioactive lipid known for its anti-inflammatory, anti-oxidative, immunomodulatory, and neuroprotective properties, which may contrast/mitigate Alzheimer's disease (AD) pathology. This study explores the therapeutic potential of targeting fatty acid amide hydrolase (FAAH), the major enzyme degrading AEA, in mouse models of amyloidosis (APP/PS…
Background Corticobasal degeneration (CBD) presents with a range of clinical phenotypes, making diagnosis challenging. We report the clinical course of a patient with autopsy-confirmed CBD who initially presented with cognitive impairment and apathy, without motor symptoms. Case presentation A 51-year-old man presented to our hospital with decreased motivation, amnesia, and executive dysfunction. Memory disturbanc…
The assembly of tau into filaments defines tauopathies, a group of neurodegenerative diseases including Alzheimer's disease (AD), Pick's disease (PiD), corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP). The seeded aggregation of tau has been modeled in cell culture using pro-aggregate modifications such as truncation of N- and C-termini and point mutations within the microtubule-binding rep…
Open article record in new tab ↗Introduction Second-generation tau-PET tracers like [18F]MK-6240 are increasingly used both for diagnosing and quantifying Alzheimer's Disease (AD) tauopathy. However, while [18F]MK-6240 tau-PET has demonstrated excellent sensitivity for AD tauopathy, data assessing its specificity and binding in non-AD tauopathies are still scarce. Methods Participants were assigned to exclusive categorical diagnoses based on the…
The endocannabinoid system is a critical brain signaling pathway that is dysregulated in various brain disorders, including Alzheimer's disease (AD). Cannabinoid-targeted therapies and imaging approaches have gained increasing interest; however, the biological impact of the endocannabinoid system in disease needs further validation. We aimed to study changes in cannabinoid receptor 1 (CB1) and monoacylglycerol lip…
Recent studies suggest that increased cerebrospinal fluid (CSF) phospho-tau is associated with brain amyloid pathology rather than the tau pathology. However, confirmation using gold standard neuropathological assessments remains limited. This study aimed to determine background pathologies associated with aberrant CSF p-tau181 and amyloid-beta 1-42 (Aβ42) in Alzheimer's disease (AD) and other neurodegenerative di…
Background Alzheimer's disease (AD) is a prevalent, incurable, and chronic neurodegenerative condition characterized by the accumulation of amyloid-β protein (Aβ), disrupting various bodily systems. Despite the lack of a cure, phenolic compounds like cannabidiol (CBD), a non-psychoactive component of cannabis, have emerged as potential therapeutic agents for AD. Objective This systematic review explores the impact…
Cannabinoids are compounds isolated from cannabis and are also widely present in both nervous and immune systems of animals. In recent years, with in-depth research on cannabinoids, their clinical medicinal value has been evaluated, and many exciting achievements have been continuously accumulating, especially in the field of neurodegenerative disease. Alzheimer's disease is the most common type of neurodegenerati…
Open article record in new tab ↗Alzheimer's disease is the most frequent neurodegenerative disease and is characterized by progressive cognitive impairment and decline. NSCs (neural stem cells) serve as beneficial and promising adjuncts to treat Alzheimer's disease. This study aimed to determine the role of miR-153-3p expression in NSC differentiation and proliferation. We illustrated that miR-153-3p was decreased and GPR55 was upregulated durin…
Open article record in new tab ↗Corticobasal syndrome (CBS) is a clinical syndrome characterised by progressive asymmetric limb rigidity and apraxia with dystonia, myoclonus, cortical sensory loss and alien limb phenomenon. Corticobasal degeneration (CBD) is one of the most common underlying pathologies of CBS, but other disorders, such as progressive supranuclear palsy (PSP), Alzheimer's disease (AD) and frontotemporal lobar degeneration with T…
Open article record in new tab ↗Older people represent the fastest growing group with epilepsy diagnosis. For example, cerebrovascular disease may underlie roughly 30-50% of epilepsy in older adults and seizures are also an underrecognized comorbidity of Alzheimer's disease (AD). As a result, up to 10% of nursing home residents may take antiseizure medicines (ASMs). Despite the greater incidence of epilepsy in older individuals and increased ris…
Open article record in new tab ↗Alzheimer's disease is the most common neurodegenerative disease. Prior to 2017, National Medical Products Administration approved only four drugs to treat Alzheimer's disease, including three cholinesterase inhibitors and one N-methyl-D-aspartate receptor antagonist. We queried ClinicalTrials.gov to better understand Alzheimer's drug development over the past 5 years and found 16 promising candidates that have en…
Open article record in new tab ↗In humans, associative memories are more susceptible to age-related cognitive decline (ARCD) than are recognition memories. Reduced cAMP/cGMP signaling in the hippocampus may contribute to ARCD. Here, we found that both aging and traumatic brain injury-associated dementia increased the expression of the cAMP/cGMP-degrading enzyme phosphodiesterase 11A (PDE11A) in the human hippocampus. Further, age-related increas…
Aims This study aimed to develop a deep learning-based model for differentiating tauopathies, including Alzheimer's disease (AD), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD) and Pick's disease (PiD), based on tau-immunostained digital slide images. Methods We trained the YOLOv3 object detection algorithm to detect five tau lesion types: neuronal inclusions, neuritic plaques, tufted astroc…
