NeurologyAdvisor: A new study looks at how people with insomnia frequently misperceive how much and how well they sleep each night.
Data is lacking on predicting factors for sleep, and previous studies have indicated a discrepancy between self-reported and objective sleep parameters. To assess self-reported sleep perception in patients with sleep disorders, researchers in this study retrospectively evaluated 303 polysomnography (PSG) tests conducted between 2012 and 2016 at a single sleep lab.
Each patient underwent a comprehensive semi-structured interview on their general and sleep history prior to PSG testing. The investigators applied linear regression to predict discrepancies between self-reported and objective sleep parameters, including total sleep time (TST), sleep efficiency (SE), and sleep latency (SL).
