Therapeutic Potential of Oxiracetam in Neurocognitive Disorders: A Narrative Review.
Review in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeCognitive impairment is a growing global health concern associated with aging, neurodegenerative diseases, stroke, and traumatic brain injury. Existing pharmacological treatments, including cholinesterase inhibitors and memantine, provide limited and variable benefits. This review aims to evaluate the mechanistic basis, clinical efficacy, and safety profile of oxiracetam as a potential therapeutic agent for cognitive dysfunction across a range of neurological disorders.
methodsA narrative review was conducted by synthesizing available preclinical and clinical literature on oxiracetam. Mechanistic studies evaluating its pharmacodynamics, including effects on cholinergic and glutamatergic pathways, synaptic plasticity, neuroinflammation, and oxidative stress, were analyzed. Clinical evidence from trials involving patients with traumatic brain injury, stroke, vascular cognitive impairment, and dementia was reviewed.
findingsOxiracetam demonstrates multimodal mechanisms of action, including enhancement of cholinergic neurotransmission, modulation of AMPA receptors, and promotion of synaptic plasticity and long-term potentiation. Additionally, it exhibits antioxidant and anti-inflammatory effects contributing to neuroprotection. Clinical studies suggest potential cognitive benefits in several neurological conditions; however, results are heterogeneous, with some trials showing significant improvement and others demonstrating no superiority over placebo.
conclusionOxiracetam is a promising neurocognitive modulator with a favorable safety profile and potential therapeutic applications across multiple neurological disorders. Nevertheless, current evidence is limited by methodological constraints and inconsistent outcomes. Further large-scale, multicenter clinical trials are required to establish its definitive efficacy and clinical utility.
