Sleep differences recur in early psychosis, but their significance remains uncertain
Compared with healthy controls, people experiencing early psychosis or considered clinically at high risk frequently took longer to fall asleep and showed changes in deep sleep.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Compared with healthy controls, people experiencing early psychosis or considered clinically at high risk frequently showed longer times to fall asleep and changes in slow-wave, or deep, sleep. Their clinical meaning remains unclear. The review describes relationships between sleep and symptoms, but does not establish that improving sleep improves psychosis or everyday functioning.
This abstract-based account provides no pooled size of the sleep differences or clear follow-up periods. The authors explicitly call for research clarifying clinical significance and testing sleep-focused interventions.
What sleep measures capture
Sleep latency means the time taken to fall asleep; slow-wave sleep refers to a deep sleep stage. These were frequently altered in the reviewed clinical groups, but the abstract does not quantify a common difference across studies.
Keep the clinical context
The review included both people already experiencing psychosis and a separate group considered clinically at high risk. Its results concern those populations and cannot turn a person's sleep complaints into evidence that they have or will develop psychosis.
