Sleep disorders linked to brain changes affecting attention and emotions

A scientific study has found that the effects of sleep disorders go beyond daytime fatigue, extending to changes in brain regions responsible for attention, decision-making, and emotional regulation.

Researchers at Florida International University analyzed the results of 57 previous studies that used brain imaging techniques, comparing individuals with various types of sleep disorders. They found these disorders were linked to changes in key brain areas, including the posterior cingulate cortex and the thalamus—regions associated with behavior, emotions, information processing, and focus.

The researchers noted that these changes may explain symptoms experienced by those with sleep disorders, such as mood swings, poor emotional control, and reduced attention. This could increase the risk of accidents, especially among older adults who suffer from fragmented sleep.

Dr. Matthew Sutherland, a cognitive neuroscientist at the university and lead author of the study, said: "The research offers a broader understanding of how sleep disorders affect the brain's structure and function, and may help develop more precise treatments and tailored care for patients."

Experts added that the findings could contribute to the development of diagnostic tools and targeted therapies for various sleep disorders, supporting the maintenance of brain functions related to attention, decision-making, and emotional balance.
