Brain Scans Reveal How Poor Sleep Fuels Negative Emotions in Alcohol Addiction
A new study in Drug and Alcohol Dependence examined 115 adults with alcohol use disorder (AUD) and found that poor sleep is strongly associated with heightened negative emotions, but not with craving or executive function. Functional MRI revealed that poor sleepers exhibited greater activity in the medial prefrontal and posterior cingulate cortices when viewing negative images, indicating heightened rumination. A second, independent sample of 102 AUD patients confirmed the link using a different insomnia questionnaire. Researchers suggest that treating sleep disturbances could mitigate emotional distress, a common trigger for relapse.
People with Social Anxiety Experience More Meaningful Interactions in Small Groups
