Prolonged grief disorder prevalence in adults 65 years and over: a systematic review.

This first review on PGD prevalence in older adults suggests that, despite studies' methodological short comings, a similar proportion of older adults experience PGD as the general bereaved adult population (1:10). With older adults forming the largest subgroup among the bereaved, health and social care systems need to adapt their provision of care to address the specific needs of older adults.
