Effects of the COVID-19 Pandemic on the Number of New Dementia Diagnoses and the Quality of Dementia Diagnostics and Treatment.
Article in The journal of prevention of Alzheimer's disease, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundCare trajectories were disrupted during the COVID-19 pandemic. However, how COVID-19 influenced the number of new dementia diagnoses, and the quality of dementia work-ups, and treatment is understudied.
objectiveTo investigate the change in new dementia registrations, diagnostics, and treatment in the pre-, COVID-19 and post-COVID-19 pandemic periods.
designA nationwide cohort study.
settingThis population-based study used data from the Swedish Registry for Cognitive/Dementia disorders - SveDem, and other nationwide registries in Sweden.
participantsPersons with dementia diagnosed between 2019 and 2021 were divided into three groups based on the date of diagnosis: the pre-COVID-19 period (01 January 2019 - 29 February 2020), the COVID-19 period (01 March 2020 - 31 December 2020), and the post-COVID-19 period (01 January 2021 - 31 August 2021). MEASUREMENTS: Outcomes included dementia diagnostics and treatments.
resultsThe monthly average number of new dementia cases registered in SveDem was 595, 415 and 470, respectively in the pre-COVID-19, COVID-19 and post-COVID-19 period. Compared to the pre-COVID-19 period, the monthly number of registrations decreased, but provision of the basic diagnostic work-up, its individual tests, and the use of cholinesterase inhibitors, memantine and antipsychotics were not significantly different in the COVID-19 period. Compared to the pre-COVID-19 period, new dementia diagnoses continued to be low in the post-COVID-19 period, but diagnosed individuals were more likely to receive the complete basic diagnostic work-up (OR 1.14, 95% CI 1.00 - 1.29), blood analysis (OR 1.88, 95% CI 1.44 - 2.49), computed tomography and magnetic resonance imaging (OR 1.22, 95% CI 1.01 - 1.48), occupational therapy assessment (OR 1.13, 95% CI 1.04 - 1.22), and memantine (OR 1.19, 95% CI 1.07 - 1.31).
conclusionThe quantity of new dementia registrations in SveDem decreased in the COVID-19 period and has not returned to pre-COVID-19 levels, but the quality of the work-ups which were conducted and registered in SveDem was similar or higher than in the pre-COVID-19 period. It is imperative to implement policies to increase SveDem registration with the aim of matching or exceeding pre-COVID-19 levels.
