Towards characterizing subjective cognitive decline in older adults.
Article in Journal of Alzheimer's disease : JAD, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BackgroundSubjective cognitive decline (SCD), where older adults perceive a persistent decline of cognitive abilities without showing an objective cognitive impairment, may represent a preclinical stage of Alzheimer's disease (AD) in some individuals.ObjectiveThe complex characteristics of SCD cannot only be revealed by existing self-report questionnaires. Rather, it is necessary to involve individuals affected in the research process with methods like focus group discussions (FGDs).MethodsStudy conduction took place in three steps: telephone interview, neuropsychological assessment and questionnaires, four FGDs with 16 older adults (11 female, 5 male) affected by SCD. FGDs were analyzed with qualitative content analysis using an inductive - deductive code system.ResultsAlthough the neuropsychological assessments did not indicate a cognitive impairment, participants reported a decline for all cognitive domains within the FGDs, especially for the memory- and speech domain, with declining word-finding abilities as the most salient symptom. Participants reported strong concerns related to SCD and difficulties in social participation.ConclusionsSCD seems to go beyond age-related cognitive changes, but as individuals do not show an objective cognitive impairment (yet), their symptoms are often not taken seriously enough. The FGDs revealed information that questionnaires or neuropsychological tests do not capture. The gained insight into SCD symptoms, related coping strategies and concerns is important to be able to develop measures for identifying individuals at risk for a transition to AD and to develop intervention measures that aim at delaying a further decline and increasing the quality of life of individuals affected.
