Brief Summary

After losing a loved one, most successfully navigate acute grief and adapt to the loss within about 1 year, but in about 10%, prolonged grief disorder (PGD) ensues. This study is anticipated to provide novel evidence regarding the neurobiological mechanisms of PGD in older adults. The biological alterations identified here could provide targets to elucidate how currently available therapies work and inform novel mechanism-based interventions for treating late-life PGD.

Outcome Measures

Primary Outcomes (1)

  • Score on the Prolonged Grief 13-Revised (PG-13-R) scale

    We will measure change in the PG-13-R score from baseline to end of study. The PG-13-R scores range from 10 - 50 (higher scores indicate more severe grief symptoms).

    Baseline through study completion, up to 10 weeks
