Prosopis cineraria is traditionally used to enhance cognitive function and manage mental disorders. Its stem bark is valued in ethnomedicine, but its potential anti-Alzheimer's disease (AD) effects are scientifically unexplored. This research has examined the neuroprotective effects of the ethyl acetate fraction of P. cineraria bark (Pc-EA) against AlCl Diseased rats were treated with Pc-EA (30, 100, and 300 mg/kg) for 42 days. Cognitive and affective functions were evaluated with behavioral tests on days 29-42. Biochemical assays measured oxidative stress and cholinesterase activity, while RT-PCR quantified neuroinflammatory markers. Histopathological examination was performed to evaluate the integrity of hippocampal regions. Bioactive compounds were identified by phytochemical profiling (HPLC, GC-MS), and molecular docking was performed to assess binding interactions with acetylcholinesterase. AlCl Pc-EA demonstrated multi-targeted neuroprotection in AlCl Show less

Post-stroke depression (PSD) is a common and clinically significant complication of stroke, associated with worse rehabilitation potential and increased mortality risk. The prevalence of PSD varies from 25% to 59%, depending on the duration of follow-up, peaking in the first years after the stroke event. The pathogenesis of PSD results from a complex interplay of biological and psychological factors, extending far beyond monoamine deficiency. Key roles are played by damage to monoaminergic pathways, neuroinflammation, dysfunction of the hypothalamic-pituitary-adrenal axis, reduced neuroplasticity (including BDNF deficit), and impaired integrity of neuronal networks. The clinical picture is characterized by a complex of affective (apathy, anhedonia), cognitive (executive dysfunction), and dyssomnic disorders. Although selective serotonin reuptake inhibitors remain the first-line treatment, the modern therapeutic approach to PSD requires targeting all components of its pathogenesis. A promising direction is the use of antidepressants with a multimodal mechanism of action, such as the original drug fluvoxamine, which combines serotonergic effects with anti-inflammatory and neuroprotective properties via sigma-1 (σ1) receptor agonism. Optimizing PSD treatment is achievable through the implementation of a personalized approach, including long-term screening and comprehensive management of the identified disorders. Show less

ObjectivesThis study aimed to compare the effects of different exercise interventions on brain-derived neurotrophic factor (BDNF) levels in patients with neurodegenerative diseases and to explore regulatory factors.MethodsSearched PubMed, Scopus, Web of Science Core Collection, CNKI and Cochrane Library databases up to March 15, 2025. Bayesian network meta-analysis was conducted using R software, and meta-regression analyzed the moderating effects of training period and frequency.Results42 randomized controlled trials covering 1482 patients were included. The Surface Under the Cumulative Ranking (SUCRA) indicated that stretching training (SUCRA = 78.92) and high-intensity interval training (SUCRA = 69.73) were ranked higher than other exercise modalities and exhibited more favorable effect on BDNF enhancement, although neither demonstrated statistically significant superiority over the blank control. In contrast, combined training (SUCRA = 35.58), aerobic training (SUCRA = 35.17), and resistance training (SUCRA = 12.98) showed relatively lower potential for BDNF enhancement (blank control SUCRA = 67.62). Meta-regression analysis showed that the effect of combined training was significantly and positively correlated with intervention period ( Show less

Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post-exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group. Sixty young, healthy participants (n = 30 female, age: 23 [3] years) were randomised into one of four groups: control (CON), aerobic exercise (EX), local heating (HEAT), or combined heat and exercise (HEATEX). Participants completed supervised sessions three times per week for 8 weeks. Exercise sessions were completed at 70-75% of maximum heart rate on a cycle ergometer, and local heating sessions involved hot water immersion (42°C) of the feet (both 45 min duration). The HEATEX group performed both the EX and HEAT components sequentially in the same session (90 min total duration). Cognitive performance was measured at baseline and at the end of the 8-week intervention using the digit symbol substitution task (DSST) and the Stroop test. There was a main effect of time (P < 0.001) where DSST performance improved; however, there was no group effect (P = 0.089) or time by group interaction (P = 0.119). There was no effect of the interventions on Stroop cost (baseline: 90 [SD: 70] ms; post-intervention: 84 [SD: 70] ms; time by condition interaction P = 0.205). Similarly, there were no effects of the interventions on circulating plasma concentrations of brain-derived neurotrophic factor (interaction P = 0.189). Eight weeks of exercise training and/or local heating is not sufficient to improve cognitive performance in young, moderately fit individuals. Show less
