Alzheimer's disease (AD) and non-AD tauopathies are dominant public health issues driven by several factors, especially in the aging population. The discovery of first-generation radiotracers, including [18F]FDDNP, [11C]PBB3, [18F]flortaucipir, [18F]THK series, for vivo detection has marked a significant breakthrough fields neuroscience radiopharmaceuticals, creating robust new category labeled compounds: tau positron emission tomography (PET) tracers. Subsequently, other PET tracers with improved binding properties have been developed using various chemical scaffolds to target three-repeat/four-repeat (3R/4R) folds AD. In 2020, [18F]flortaucipir was approved U.S. Food Drug Administration imaging pathology adult patients cognitive deficits undergoing evaluation Despite remarkable progress development AD tracers, agents rare (4R [predominantly expressing 4R isoform], involved progressive supranuclear palsy, corticobasal degeneration, argyrophilic grain disease, globular glial tauopathy, 3R such as Pick's disease) remain substantially underdeveloped. this review, we discuss recent tracer development, particular emphasis on clinically validated their potential use tauopathies. Additionally, highlight critical need further specifically designed tauopathies, an area that remains significantly underexplored despite its importance advancing understanding diagnosis these disorders.

Abstract Alzheimer’s disease (AD) is a neurodegenerative condition that causes cognitive decline, memory loss, and reduced personal autonomy. The pathology of AD involves the aggregation abnormal brain proteins, specifically beta-amyloid plaques tau tangles, disrupting neuronal communication leading to loss cells. Aducanumab, monoclonal antibody, demonstrates promise in clinical trials by selectively binding aggregated amyloid-beta, notable decrease plaque burden potential benefits. However, regulatory approval for aducanumab remains controversial. Lecanemab donanemab are recent additions AD’s treatment landscape, both targeting amyloid-beta. shares similarities with its mechanism action, while employs distinct approach specific truncated form Positive outcomes have been observed early-stage drugs, demonstrating reduction amyloid-beta plaques. While aducanumab’s offers hope treatment, ongoing studies on lecanemab imperative comprehensive understanding their modification. Here, we show this review treatments, focus primary action ultimately giving broader insight topic. emphasizes necessity long-term efficacy safety data assess overall impact these drugs decline functional future researchers endeavor. In conclusion, development antibodies represents significant stride demanding further investigation ascertain true role therapeutic arsenal challenging condition.

The clinical features and pathophysiology of neuropsychiatric symptoms (NPSs) in dementia have been extensively studied. However, the genetic architecture underlying neurobiological mechanisms NPSs at preclinical stages cognitive decline Alzheimer's disease (AD) remain largely unknown. Mild behavioral impairment (MBI) represents an at-risk state for incident is defined by emergence persistent among non-demented individuals later life. These include affective dysregulation, decreased motivation, impulse dyscontrol, abnormal perception thought content, social inappropriateness. Accumulating evidence has recently begun to shed more light on background MBI, focusing its potential association with factors related AD.

Neurodegenerative diseases encompass a spectrum of disorders marked by the progressive degeneration structure and function nervous system. These conditions, including Parkinson's disease (PD), Alzheimer's (AD), Huntington's (HD), Amyotrophic lateral sclerosis (ALS), Multiple (MS), often lead to severe cognitive motor deficits. A critical component neurodegenerative pathologies is imbalance between pro-oxidant antioxidant mechanisms, culminating in oxidative stress. The brain's high oxygen consumption lipid-rich environment make it particularly vulnerable damage. Pro-oxidants such as reactive nitrogen species (RNS) (ROS) are continuously generated during normal metabolism, counteracted enzymatic non-enzymatic defenses. In diseases, this balance disrupted, leading neuronal This systematic review explores roles stress, gut microbiota, epigenetic modifications aiming elucidate interplay these factors identify potential therapeutic strategies. We conducted comprehensive search articles published 2024 across major databases, focusing on studies examining relationships redox homeostasis, changes neurodegeneration. total 161 were included, comprising clinical trials, observational studies, experimental research. Our findings reveal that stress plays central role pathogenesis with microbiota composition significantly influencing balance. Specific bacterial taxa markers identified modulators suggesting novel avenues for intervention. Moreover, recent evidence from human animal supports emerging concept targeting homeostasis through therapies. Future research should focus validating targets settings exploring personalized medicine strategies based individual profiles.
