Article Abstract
Purpose: Cancer-related cognitive impairment is one of the symptoms of neurotoxicity among patients receiving chimeric antigen receptor (CAR) T cell therapy. Evidence of the overall estimated prevalence of cancer-related cognitive impairment following CAR T-cell therapy among patients with hematologic malignancies at short-term and long-term follow-ups is lacking. This review aimed to summarize the cognitive functioning status and estimate the prevalence of cancer-related cognitive impairment at follow-up within 1 month, 1 to 12 months, and > 12 months after CAR T cell therapy.
Methods: PubMed, Cochrane Library, EMBASE, CINAHL Plus, Web of Science, and PsycINFO via ProQuest from inception through August 2024. Studies that reported on cognitive impairment among patients receiving CAR T cell therapy with valid measures were included. Data on cognitive impairment prevalence were pooled using a random-effects model.
Results: In total, 16 studies involving 1407 patients were included. The pooled cancer-related cognitive impairment prevalence rates assessed using neuropsychological tests at the follow-up timepoints (< 1 month, 1-12 months, and > 12 months) were 24% [95% prediction interval (PI) 16-33%], 33% (95%, PI 9-64%), and 35% (95%, PI 23-48%), respectively. The prevalence estimates assessed using other measures were ranging from 4 to 38% across different timepoints. The leave-one-out meta-analyses quantified the impact of these potential outliers on the estimation of the overall prevalence.
Conclusions: The findings stress the importance of developing targeted interventions to prevent or manage cognitive impairment in cancer patients during both short-term and long-term follow-up periods. This review also highlights the need for further research in this area to improve our understanding of the disease mechanisms and implement preventive strategies for managing cancer-related cognitive impairment.

Rationale: One of the earliest changes associated with Alzheimer's disease (AD) is the loss of catecholaminergic terminals in the cortex and hippocampus originating from the Locus Coeruleus (LC). This decline leads to reduced catecholaminergic neurotransmitters in the hippocampus, affecting synaptic plasticity and spatial memory. However, it is unclear whether restoring catecholaminergic transmission in the terminals from the LC may alleviate the spatial memory deficits associated with AD.

Licochalcone A (LCA), a natural flavonoid with potent anti-inflammatory properties, has shown promise as a neuroprotective agent. However, its ability to cross the blood-brain barrier (BBB) and exert central effects remains underexplored. In this study, we demonstrate for the first time that LCA enhances cognitive function in a lipopolysaccharide (LPS)-induced neuroinflammatory mouse model and effectively penetrates the BBB.

Objectives: This study aimed to investigate the effects of repeated exposure to sevoflurane as an anesthetic agent during various developmental stages, namely neonatal, preadolescent, and adult, on behavioral, synaptic, and neuronal plasticity in male and female Wistar rats.
Methods: Rats were exposed to sevoflurane during three developmental stages: neonatal (PN7), pre-adolescence (PN28), and adulthood (PN90). Behavioral performance was evaluated with the Morris Water Maze.

Background Elevated brain iron is a potential marker for neurodegeneration, but its role in predicting onset of mild cognitive impairment (MCI) and prospective cognitive trajectories remains unclear. Purpose To investigate how brain iron and amyloid-β (Aβ) levels, measured using quantitative susceptibility mapping (QSM) MRI and PET, help predict MCI onset and cognitive decline. Materials and Methods In this prospective study conducted between January 2015 and November 2022, cognitively unimpaired older adults underwent baseline QSM MRI.
