Childhood abuse is linked to posttraumatic stress disorder (PTSD), which follows abuse survivors into adulthood. This study identified the neuropsychological and neuromorphological sequelae of PTSD among prepubescently abused women. Right-handed women aged 20-40 years were placed into PTSD and abuse, abuse only, and normal control groups (n = 17 per group). Participants were screened for trauma history and psychiatric symptoms, demographically matched, and given neuropsychological tests and a magnetic resonance scan of their brain. Women with PTSD did not express significant deficits in memory performance or hippocampal volume when compared with the abuse and normal control groups.
The data suggest unusually ambitious, effortful task engagement may contribute to the onset of mild "ordinary" headache. This possibility requires further examination under other controlled conditions as well as in the natural environment.
The reduced ability to perform tasks is generally reported by those who experience headache. However, in an experimental study, participants reporting onset of headache chose more ambitious tasks than participants remaining headache free. The purpose of this study was to reevaluate the objective ambition of subjects with headache onset, and to determine if perceptions of expended effort and performance accuracy contributed to this seemingly maladaptive behavior. These effects were evaluated while controlling for headache proneness. A nonclinical sample was used. Measures of ambition, performance accuracy, perceived effort, and perceived accuracy for a headache-developing group (n = 25) and a sex-matched, headache-free group (n = 25) were compared during a series of mental arithmetic problems. Ambition among participants after headache onset was significantly higher than for the control group. There was little indication that inaccurate perceptions of effort or accuracy contributed to the observed heightened ambition. However, perceived accuracy was poorer for the headache-developing group after onset of a headache state. Headache proneness did not eliminate the significance of any relationship between objective or subjective performance and headache state.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
