Description
Annika Steinkogler leads a 2026 study using wrist actigraphy, a watch-like motion tracker, to study sleep in Cushing's syndrome. In this condition the body makes too much cortisol, a hormone that should fall at night. Sleep problems are common and can persist after remission.
Participants wore the tracker for 21 days and gave nightly saliva samples. In the suspected group, 16 confirmed cases and 13 excluded cases showed similar sleep, apart from an earlier daily rhythm in confirmed cases. In 23 patients in remission, sleep was also similar across subgroups. Night cortisol varied a lot and showed no steady link to the sleep measures.
