Abstract
BACKGROUND: Symptoms of posttraumatic stress disorder (PTSD) reflect abnormalities in large-scale brain networks. In individuals with recent trauma exposure, we examined associations of seed-based resting-state functional connectivity (rs-FC) with posttraumatic symptoms and sleep. We hypothesized that more severe PTSD symptoms and poorer sleep quality would predict 1) greater rs-FC between fear-related seeds and other fear-related regions and 2) lesser rs-FC between fear-related seeds and emotion-regulatory regions. METHODS: Seventy-four participants who had experienced a DSM-5 criterion A stressor within the past 2 years and ranged from asymptomatic to fully meeting criteria for PTSD diagnosis underwent 14 days of actigraphy and sleep diaries, a night of ambulatory polysomnography, and a functional magnetic resonance imaging resting-state scan at 3T. rs-FC measures of 5 fear-related seeds and 1 emotion regulatory seed with regions of the anterior cerebrum were correlated with PTSD symptoms, objective and subjective habitual sleep quality, and sleep architecture. RESULTS: Longer objective habitual sleep onset latency was associated with greater connectivity between fear-related seeds and other regions of the salience network. Greater PTSD symptoms were associated with less connectivity between fear-related seeds and anterior emotion regulatory regions, whereas greater percent slow wave sleep was associated with more connectivity between these regions. However, other objective and subjective measures reflecting better habitual sleep quality were associated with less rs-FC between these regions. CONCLUSIONS: Longer sleep onset latency predicted greater rs-FC among fear-related areas. More severe PTSD symptoms predicted less rs-FC between fear and fear regulatory regions reflecting putatively reduced top-down fear regulation. Some (e.g., percent slow wave sleep), but not all sleep indices predicted greater top-down fear regulation.
