Article Abstract
Late-life depression (LLD) is a prevalent mental health issue that significantly impacts the quality of life in the elderly population. In recent years, metabolomics has emerged as a novel research tool, offering fresh insights into the molecular mechanisms underlying LLD. This systematic review synthesizes metabolomic studies from January 2004 to March 2024, aiming to identify differential metabolites, explore diagnostic and predictive potential, and investigate aberrant metabolic pathways in LLD. A total of 12 relevant studies were included, revealing differential metabolites such as amino acids and fatty acids, as well as associated metabolic pathways. The study's findings provide insights into the prediction and diagnosis of LLD, highlighting the multifaceted metabolic disturbances associated with the condition. By synthesizing existing literature, we highlight the importance of metabolomic research in identifying biomarkers for LLD and potential therapeutic targets, addressing current gaps in understanding the pathophysiology of this condition.

Background: Late-life depression (LLD) is associated with negative outcomes including high rates of recurrence and cognitive decline. However, the neurobiological changes influencing such outcomes in LLD are not well understood. Disequilibrium in large-scale brain networks may contribute to LLD-related cognitive decline.

We evaluated cognitively unimpaired older adults to identify specific GM patterns, their clinical and cognitive profiles, and longitudinal trajectories. Methods We analyzed 746 participants from the Gothenburg H70 Study using random forest clustering based on MRI measures of cortical thickness and subcortical volume across 41 regions.

Late-life depression (LLD) arises from the confluence of neurochemical dysfunction, oxidative stress, and neural network disintegration, presenting a formidable therapeutic challenge. Here, we demonstrated that combined vitamin D (Vit D) and L-theanine (L-thea) administration exerts multimodal neurorestorative effects in an aged murine model of unpredictable chronic mild stress (UCMS), addressing the core triad of LLD pathology: dopaminergic decline, redox imbalance, and thalamocortical dyssynchrony. Using a comprehensive battery of behavioral assays (Open Field Test, Elevated Plus Maze, Hole Board Test, Tail Suspension Test, Forced Swim Test, Sucrose Preference Test), we observed profound anxiogenic and anhedonic phenotypes in the UCMS-exposed mice, accompanied by elevated immobility and suppressed exploratory drive.
