Episodic memory in aging: neurocognitive bases and clinical implications of the distinction between hippocampal and frontal patterns.
Review in Dementia & neuropsychologia, 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
Episodic memory is one of the cognitive domains most vulnerable to age-related changes and the early stages of neurodegenerative syndromes. In Brazilian clinical practice, however, the interpretation of memory performance frequently remains restricted to the quantitative analysis of delayed recall, without adequate consideration of the underlying neurocognitive mechanisms. This study aimed to critically examine the neurobiological foundations of the distinction between hippocampal consolidation deficits and executive retrieval impairments mediated by prefrontal circuits, discussing their diagnostic and gerontological implications. This integrative narrative review is grounded in recent national and international literature (2019-2024) and integrates evidence from neuroimaging, theoretical models of memory, and clinical data relevant to aging. Differentiating hippocampal consolidation deficits from executive retrieval impairments, integrated with the assessment of functional capacity, is proposed as a clinically actionable, mechanism-based framework for improving diagnostic accuracy in aging within heterogeneous sociocultural contexts such as Brazil.
