Registry
Anxiety Disorders — the first condition term the registry derived for this study.

Memory Disorders
Why
  1. The registry often attaches Anxiety Disorders to studies about something else, and this study's title and listed conditions do not name it.
  2. The study's listed conditions name Memory Disorders.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2022 to primary completion in Oct 2022, 3 months.

Of 138 interventional studies with no phase under Memory Disorders, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 53. This study's 3 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 8, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
