Florida International University scientists find brain changes linked to sleep disorders

Study combines fifty seven imaging results

Researchers at Florida International University analyzed data from fifty seven brain imaging studies to examine adults with sleep issues. The team combined these findings to reveal physical changes in regions controlling attention and decision making. Published in Scientific Reports, the work offers one of the broadest examinations of how disrupted sleep alters brain structure.

Two disorder groups show shared patterns

The analysis focused on dyssomnias like insomnia and sleep apnea alongside parasomnias including sleepwalking and nightmare disorder. Both groups showed reductions in the thalamus, a deep brain structure vital for processing information and sustaining attention. Scientists identified specific changes in the pulvinar region which helps direct attention toward important information during tasks.

Findings could enable earlier diagnosis

Matthew Sutherland, a cognitive neuroscientist at FIU, stated that bringing together results from many studies provides a clearer picture of brain function. Such findings could enable researchers to detect sleep issues sooner and create therapies customized for particular brain networks linked to these conditions.
