Newest studies

Every summary in our library, newest first, as a dated timeline.

What "newest" means here

The most recent study in this library is dated 2026-11-01 (Paths of Aging Minds: Health Journeys of Older Adults with Mild Cognitive Impairment). This is our summary library, not a news wire — it is added to in batches, so the newest entry may not be the newest paper published anywhere.

Entries are sorted strictly by publication date, newest first. 26889 of the 27780 entries carry a full day-level date. 65 have no date recorded at all and are placed by publication year, at the start of that year; those are marked "no date recorded" below so you can see where the ordering is a best effort rather than a fact.

    Alterations in the circadian rest-activity rhythm in aging and Alzheimer's disease

    ✓ Peer-reviewed Risk factors Biological psychiatry

    Key finding: Comparison of old controls versus AD patients revealed that (1) rest-activity rhythm was markedly disturbed in many of the AD patients and tended to be correlated with the severity of the dementia; (2) disturbances were most pronounced in subjects using sedating drugs; (3) disturbances in the latter group did not result from medication as no differences were found in the rest-activity patterns before and after administration of sedating drugs; (4) negative findings reported in the literature concerning circadian disturbances in AD may well have resulted from selection criteria that excluded the group of patients with the most severely affected rest-activity rhythm; and (5) rest-activity monitors offer a practical and fruitful approach for the study of circadian rhythms in humans.
