Using narratives to reflect on experiences, emotions, and thoughts is associated with better health, enhanced mood, and improved symptoms of posttraumatic stress disorder (PTSD). Prior research examining narrative characteristics thought to reflect cognitive styles associated with PTSD has focused on trauma narratives, but the characteristics of nontrauma narratives in relation to PTSD are not fully understood. We reviewed the PTSD literature examining linguistic characteristics of nontrauma narratives, focusing on affective content, personal pronouns, and cognitive processing words.

Humans can remember past autobiographical events through extended narratives. How these narrated memories typically unfold, however, remains largely unexplored. We evaluated how autobiographical memory details typically come together in a sample of 235 healthy young, middle-aged, and older adults.

Metabolic syndrome is a collection of health factors that increases risk for cardiovascular disease. A condition of aging, metabolic syndrome is associated with reduced brain network integrity, including functional connectivity alterations among the default mode, regions vulnerable to neurodegeneration. Prevalence of metabolic syndrome is elevated in younger populations including post-9/11 Veterans and individuals with posttraumatic stress disorder, but it is unclear whether metabolic syndrome affects brain function in earlier adulthood.

Metabolic syndrome has been associated with reduced brain white matter integrity in older individuals. However, less is known about how metabolic syndrome might impact white matter integrity in younger populations. This study examined metabolic syndrome-related global and regional white matter integrity differences in a sample of 537 post-9/11 Veterans.

Recent research suggests that the retrieval of autobiographical memories among cognitively healthy middle-aged and older adults is sensitive to the Apolipoprotein E ε4 (APOE4) allele, a genetic marker that increases the risk of Alzheimer's disease (AD) dementia. However, whether the APOE4-associated alteration in autobiographical memory retrieval encompasses rapid (i.e.
