Key findings

What ClinicalTrials.gov does not surface for Cognitive Impairment on its own pages , computed from the registry mirror as of 2026-08-08. Each line carries its own denominator so it can be quoted as it stands.

  1. Cognitive Impairment is recruiting above its size-band peers.

    46 of 106 indexed trials (43.4%) are open to enrollment, against a 37.1% average across 139 conditions with 100+ trials. The peer set uses the same ClinicalTrials.gov-derived counts as this page.

  2. Sponsorship of Cognitive Impairment trials is spread across many organizations.

    University of Alabama at Birmingham accounts for 7 of 106 trials (6.6%). 63 distinct sponsors appear on at least one study for this condition label.

  3. Typical Cognitive Impairment enrolment sits around 83 participants.

    Median target enrolment is 83 among the 106 trials that report a genuine target (sentinel values excluded). 62 of those (58.5%) plan for fewer than 100 participants.

  4. Cognitive Impairment research is mostly interventional.

    84 interventional and 22 observational studies make up this index (79.2% interventional). Study type is sponsor-reported on ClinicalTrials.gov.
