Sleep problems are linked to poorer outcomes in schizophrenia
A review of reviews linked disturbed sleep in people with schizophrenia to worse thinking abilities, psychiatric symptoms and quality of life. It did not establish that sleep problems caused these outcomes.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
In people with schizophrenia, the reviewed evidence associated sleep disturbances with poorer thinking abilities, more severe psychiatric symptoms and reduced quality of life. Reported sleep problems included shorter sleep and taking longer to fall asleep. The abstract describes links between outcomes, but does not show whether sleep changes precede, follow or cause changes in psychiatric health.
The abstract does not report association sizes, follow-up durations or the results of its review-quality assessments. Without these details, the strength and reliability of the reported links are difficult to judge.
A review of existing reviews
An umbrella review summarizes evidence already collected in other research reviews. Here, the question was how sleep and psychosis relate in schizophrenia, rather than whether a particular sleep treatment improves symptoms or daily functioning.
Several outcomes were linked
Disturbed sleep was associated with difficulties in functioning and lower quality of life, alongside psychiatric and cognitive outcomes. These different endpoints should remain separate: a link with sleep does not establish the size of any particular clinical effect.
