Cognitive stimulation exerts long-lasting protective effects on the hippocampal vasculature and memory function in a rat model of vascular cognitive impairment.

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
Hypertensive individuals with vascular cognitive impairment (VCI) often live alone and are less likely to adhere to prescribed medications, making the development of non-pharmacological interventions critical. How cognitive stimulation affects the vasculature of the hippocampus remains unclear but could protect against memory decline during VCI. Memory and hippocampal arteriole (HA) function were assessed in spontaneously hypertensive rats (SHR) of both sexes that either underwent cognitive stimulation or lived in isolation. Isolated SHR were treated with donepezil (acetylcholinesterase inhibitor) to compare lifestyle and pharmacological interventions and investigate the mechanisms by which the hippocampus can be protected during VCI. Cognitive stimulation selectively and persistently improved hippocampal-dependent memory and HA function that was not due to increased BDNF expression. Donepezil improved HA function and rescued memory in isolated, aged SHR. Intermittent cognitive stimulation exerted long-lasting protection on the hippocampus and its vasculature, highlighting the therapeutic potential of HAs and cognitive stimulation in VCI.
