Picture Naming Test in dementia and Alzheimer's trials: 104 registered studies

Every registered dementia and Alzheimer's disease study on ClinicalTrials.gov that names the Picture Naming Test in an outcome measure: how often it is a primary outcome, the tests named with it, how large the studies are and when they measure it.

Registered dementia and Alzheimer's disease studies name it in an outcome measure: 104
Name it in a primary outcome, 37%: 38 of 104

Questions, answered from the data

How many dementia and Alzheimer's trials use the Picture Naming Test?

104 registered dementia and Alzheimer's disease studies on ClinicalTrials.gov name it in an outcome measure, 38 of them in a primary outcome: 6% of the condition's 1,673 studies with a cognitive outcome, against 3% of all of them. It is the 8th most named test in dementia and Alzheimer's trials.

Which tests do dementia and Alzheimer's trials use with the Picture Naming Test?

The Trail Making Test (50 studies), Verbal Learning (47 studies) and Verbal Fluency (45 studies).

How many participants do phase 2 dementia and Alzheimer's trials that use the Picture Naming Test enroll?

Half of the phase 2 studies that name it enroll 48 participants or fewer, and the middle half enroll 24 to 93. 12 of them give a size.

When do dementia and Alzheimer's trials measure the Picture Naming Test?

Half of the primary outcomes that name the Picture Naming Test are measured within 13 weeks of the start, and the middle half from 9 weeks to 13 months. 36 primary outcomes give a duration.

How many completed dementia and Alzheimer's trials that use the Picture Naming Test have reported results?

28 of the 39 completed studies that name it, 72%, have reported results: 13 posted them on ClinicalTrials.gov, 22 have a results paper linked to the registry record, and 7 did both. The other 11 show neither. Of all completed studies with a cognitive outcome, 46% have reported results.

How the studies are counted

For each test family, the census runs ClinicalTrials.gov's own outcome search for the family's names and reads every study first posted by the day the family was counted. These studies were read on 10 November 2026. A study counts once on a page, however many tests it names. Counts for a test cover every version of the task under any of its names, so a page can count studies that used a commercial version.

The census adds two things to each record and changes nothing in it: which outcome list names the test (primary, then secondary, then other), and the condition groups, matched on the study's condition names and MeSH terms. A study can fall in several groups; one whose only condition is cognitive impairment or decline falls in “Cognitive impairment and decline”. Studies that name only instruments outside the library count in every total and share but are not listed.

A second read on 10 November 2026 added each study's overall status, whether results are posted, its intervention types, the countries of its sites and the time frame of the outcome that names each test. A time frame counts by the latest time point it names: “Baseline, 12 and 24 weeks” is 24 weeks, a single visit is within a day, and one that names no duration, such as “end of treatment”, is left out of the timings.

A third read on 10 November 2026 added the papers the registry links to each study: those its sponsor lists as reporting results, and those PubMed links to it through the study's NCT number. A study has a results paper when one of them came out in or after the month of its primary completion and PubMed does not class it as a protocol, review or comment. A paper that never gives the NCT number is not linked, so some studies counted as reporting neither did publish.
