(HealthDay News) – Within one year following a stroke or transient ischemic attack (TIA), nearly one in four survivors develop significant posttraumatic stress disorder (PTSD) due to the stroke or TIA, according to a review published online June 19 in PLOS ONE.
Donald Edmondson, PhD, from the Columbia University Medical Center in New York City, and colleagues conducted a literature review to examine the prevalence of stroke or TIA-induced PTSD. Data were included from nine observational cohort studies involving 1,138 patients that assessed PTSD with specific reference to a stroke or TIA that occurred at least one month prior to the PTSD assessment.
The researchers found that there was significant variation across studies in the rates of PTSD based on the timing of PTSD assessment (i.e., within one year of stroke or TIA vs. greater than one-year post-stroke or TIA; 55% of heterogeneity explained). Within one year of the stroke or TIA, the estimated rate of PTSD was 23%, and the rate decreased to 11% after one year.
“Screening for PTSD in a large population-based prospective cohort study with cardiovascular outcome assessments is needed to yield definitive prevalence, and determine whether stroke or TIA-induced PTSD is a risk factor for subsequent cardiovascular events or mortality,” the authors write.
