Impact of Operational Sleep Disruption on PTSD-Relevant Fear Learning Processes

Abstract

This report covers Year 3 of the project. This project examines the impact of disturbances in normal sleep and circadian regulation on mechanisms underlying vulnerability to, and maintenance of, posttraumatic stress disorder (PTSD). The goal of Year 3 was to complete 15 participants in the study (60 total across all years), including processing and cleaning of all data. Not surprisingly, the coronavirus pandemic continued to significantly impact those plans. Our sleep lab was shut down for a total of 137 days, across 4 separate local lockdowns over the year. Nonetheless, during Year 3, 27 participants signed consent and 12 of them completed the study. At the end of this grant year, we requested a No Cost Extension. We anticipate we will not ultimately be able to meet our original recruitment goals. Thus, our plan is to drop one of our 3 conditions to allow us to focus enrollment on the other two conditions and still address key aims of the grant. This will maximize the efficiency of our remaining time for recruitment.
