Cognitive Effect of Levetiracetam in Patients with Alzheimer's Disease or Mild Cognitive Impairment: A Systematic Review.
Review in Current therapeutic research, clinical and experimental, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Various therapeutic interventions have been investigated for cognitive impairment, a common problem in Alzheimer's disease (AD). Levetiracetam (LEV), an antiepileptic drug, has been shown to alleviate cognitive impairment. Objective: The present systematic review aimed to evaluate the cognitive effects of LEV in patients with AD or mild cognitive impairment (MCI). Methods: We searched PubMed/MEDLINE, Scopus, Web of Sciences, and Embase databases for all studies on LEV and cognitive impairment. After multistep screening, we identified qualified interventional studies and performed further data extraction. We reviewed the methodological diversity across the studies and assessed the quality of each study using the critical appraisal of the Joanna Briggs Institute checklist (the risk of bias assessment). Results: Of the 1091 publications, only 5 articles were qualified for review. All studies enrolled patients with AD or MCI, and at least 1 arm of the trial involved LEV therapy. Four of 5 studies reported significant cognitive improvement in patients with AD or MCI after the LEV trials, whereas 1 study found no significant change in cognitive status. The risk of bias assessment revealed that 4 studies had a low risk of bias. Among them, 3 showed significant improvement, whereas 1 did not report a significant change in cognitive function. Conclusions: The efficacy of LEV therapy for cognitive impairment varies across studies owing to different methodologies, dosages, treatment durations, and outcome assessment tools. This study suggests that LEV may exert a beneficial impact on cognitive function in patients with AD or MCI. However, a quantitative comparison or meta-analysis is essential to draw definitive conclusions about the cognitive effects of LEV in AD and MCI.
