Hippocampal volume and memory performance in a community-based sample of women with posttraumatic stress disorder secondary to child abuse.

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).

Effects of the headache state on objective and perceived performance.

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.
