How sleep apnea affects thinking in people with schizophrenia

Cognitive Consequences of Obstructive Sleep Apnea in Schizophrenia: An Investigation of Inflammatory Mechanisms

NIH-funded research University of California, San Diego · NIH-11232322

This project looks at whether untreated sleep apnea is linked to memory and thinking problems in adults with schizophrenia by comparing them to people without psychiatric illness.

What this research studies

If I join, researchers will compare people with schizophrenia and a non-psychiatric group using overnight sleep testing to find obstructive sleep apnea, detailed thinking and memory tests, and blood tests that measure inflammation. Visits will be observational and naturalistic, meaning participants keep their usual treatments while researchers collect sleep, cognitive, and biomarker data. The team will look for connections between sleep apnea, inflammatory blood markers, and specific thinking problems to identify which brain functions are most affected. The goal is to gather the data needed to design future trials that could treat sleep apnea to help thinking in people with schizophrenia.

Who could benefit from this research

Good fit: Adults with a diagnosis of schizophrenia—particularly middle-aged or older individuals who have sleep complaints or suspected untreated sleep apnea—who can attend sleep testing and blood draw visits are the ideal participants.

Not a fit: People seeking immediate changes to their medical treatment or those already effectively treated for sleep apnea are unlikely to receive direct therapeutic benefit from this observational study.

Why it matters

Potential benefit: If successful, this work could identify treatable sleep-related causes of cognitive problems and point to blood markers that help target future treatments for people with schizophrenia.

How similar studies have performed: Similar work in the general population has linked sleep apnea and inflammation to thinking problems, but using this combined sleep, cognitive, and biomarker approach specifically in schizophrenia is relatively new.
