Background: We examined the longitudinal association between participation in individual or combinations of physical, social, and religious activity and risk of depression in the elderly.

Methods: Elderly subjects aged ≥ 60 years who completed the Living Profiles of Older People Survey in Korea (n = 6,647) were included. The baseline assessment, Wave 1, was conducted in 2008, and a follow-up assessment, Wave 2, was conducted in 2011.

Avoidance symptoms and delayed verbal memory are associated with post-traumatic stress symptoms in female victims of sexual violence.

Background: Victimization by sexual violence is strongly associated with the development of posttraumatic stress disorder (PTSD). While several psychological and cognitive factors are known to be associated with PTSD prognosis, multivariable analysis is scarce. This study examined factors affecting the severity of PTSD symptoms in early stage of traumatic experience of sexual violence, including initial post-traumatic symptoms and cognitive characteristics.

Increased plasma levels of heat shock protein 70 associated with subsequent clinical conversion to mild cognitive impairment in cognitively healthy elderly.

Background And Aims: Heat shock proteins (HSPs) have been regarded as cytoprotectants that protect brain cells during the progression of neurodegenerative diseases and from damage resulting from cerebral ischemia. In this study, we assessed the association between plasma HSP 70/27 levels and cognitive decline.

Methods: Among participants in the community-based cohort study of dementia called the Gwangju Dementia and Mild Cognitive Impairment Study, subjects without cognitive impairment at baseline, who then either remained without impairment (non-conversion group), or suffered mild cognitive impairment (MCI) (conversion group) (non-conversion group, N = 36; conversion group, N = 30) were analyzed.
