Summary
This study tested whether the drug naltrexone could help people with prolonged grief disorder, a condition where grief lasts a long time and causes severe distress. Participants took naltrexone or a placebo for 8 weeks and had monthly check-ins. However, the study was terminated early and only included 7 people, so it does not provide clear answers.
