Prolonged Grief Disorder

Brief summary

Experiencing the death of a loved one is inevitable for older adults. Before the coronavirus disease 2019 (COVID-19) pandemic, over 2.5 million people died annually in the United States, including 52,000 in Wisconsin alone, and COVID-19 has added to this toll. Each person who dies leaves an average of five grieving people behind. Most grieving older adults are resilient and recover their pre-loss functioning within one year. However, in about 10%, acute grief becomes protracted and debilitating, leading to the development of prolonged grief disorder (PGD), a clinically diagnosable mental health condition. PGD in older adults increases the risk for poorer medical, mental health, and cognitive outcomes; lower quality of life; disability; premature mortality; and suicide. Despite the magnitude of this problem, the neurobiology of PGD in older adults is poorly understood. By using Iyengar Yoga (IY) as a probe for PGD neurobiology, this pilot project aims to address this critical gap.

Detailed description

Our goal is to conduct a pilot study to examine in PGD the modulating effects of 10-week IY on circulating endocannabinoid and emotion processing brain circuit, and the associations between biological changes and clinical response.
