Prepulse inhibition and acoustic startle in cognitive impairment and dementia research

From 2021 to 2025, 49 animal research papers on cognitive impairment and dementia mentioned prepulse inhibition and acoustic startle in their title or abstract.

That is 29% fewer than the 69 papers of 2011 to 2015. Between the same two periods, the papers on cognitive impairment and dementia that mention any of the 90 tests we count rose 70%. The 2021 to 2025 count may run low because of a dip in PubMed's indexing, explained under the year chart.

Papers on cognitive impairment and dementia that mention prepulse inhibition and acoustic startle fell from 12 in 2021 to 5 in 2024, then rose to 7 in 2025. Part of this dip may come from PubMed's indexing rather than from fewer studies. Where PubMed has indexed a paper, we take its disease models from that indexing. Otherwise PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract, or the paper is not counted here. Papers that PubMed indexed under the subject heading Animals also fell and rose, from 200,221 in 2021 to 156,447 in 2023 and 235,479 in 2025.

Which species the papers used

Each bar is a share of the 49 papers from 2021 to 2025. A paper can use more than one species, so the shares can add to more than 100%.

Which papers count

A paper counts here when it is animal research, mentions prepulse inhibition and acoustic startle in its title or abstract, and studies cognitive impairment and dementia.

We tell whether a paper studies cognitive impairment and dementia from its MeSH terms, the subject headings the National Library of Medicine adds when it indexes a paper. For a paper without MeSH terms, PubTator 3, NCBI's text-mining service, has to find the disease in the title or abstract. A paper can count under more than one disease model. A paper that mentions the test only in its methods is missed, so the count runs low.

The page on cognitive impairment and dementia research names the subject headings we count as cognitive impairment and dementia. Download the test list for the search terms we used for prepulse inhibition and acoustic startle, or the paper list for the PubMed ID of every paper behind these counts. Our main page, Behavioral tests in published research, has the full method and each source's terms of use.
