The mental health of the French population has been—and continues to be—significantly affected by the deaths of loved ones due to COVID-19. Professor Éric Bui, a specialist in grief, has practiced in the United States and worked on traumatic grief (including among war veterans). Now director of the Normandy Regional Psychotrauma Center, he explains why prolonged grief is not inevitable, but that treatment must be tailored to the individual. He emphasizes that to date, only individual psychotherapy consisting of 16 sessions has robustly demonstrated its effectiveness in treating prolonged grief disorder, as shown by three large randomized trials. Conversely, he warns, no medication has been proven effective for prolonged grief disorder. In particular, commonly prescribed antidepressants are no more effective than a placebo in reducing grief symptoms.
