Sleep Deprivation: A Surprising Mood Booster for Certain Depressed Individuals

A study on sleep loss and depression found that while lack of sleep generally worsens mood in healthy individuals, it surprisingly induced a temporary lift in spirits for 43% of the patients with depression. Functional MRI scans revealed increased connectivity between the amygdala and the anterior cingulate cortex (ACC) after sleep deprivation, which improved mood in healthy participants and exhibited an antidepressant effect in the patient group. These findings could pave the way for new antidepressant treatments targeting the connectivity between these brain areas.

Brain changes hinder weight loss, says study.

A recent study published in Nature Metabolism found that the brain responds to nutrients differently in people who have obesity, even after meaningful weight loss. The study showed that the reward centers in the brain were not activated in response to nutrients in participants with obesity, which could lead to overeating and make it difficult to change eating habits that can contribute to weight gain. The findings suggest that there are biological and brain causes for overweight and obesity, and could lead to more targeted treatments for people who are overweight or have obesity.
