Frequency and predictors of post-traumatic stress disorder after stroke: a pilot study.

Objective: Few data exist about post-stroke symptoms of post-traumatic stress disorder (sPTSD) and none on DSM-IV formally diagnosed PTSD (fdPTSD). We investigated the frequency and predictors of sPTSD and fdPTSD 1-6 months after a nondisabling ischemic stroke (IS) or transient ischemic attack (TIA).

Methods: Consecutive patients were assessed for sPTSD (Impact of Events Scale-Revised, IES-R, significant if >30) and fdPTSD (PTSD-Interview).

Cortical motor activation in akinetic schizophrenic patients: a pilot functional MRI study.

Akinesia is associated with supplementary motor area (SMA) dysfunction in Parkinson's disease. We looked for a similar association in patients with schizophrenia. Using functional magnetic resonance imaging (fMRI), we compared motor activation in 6 akinetic neuroleptic-treated schizophrenic patients and 6 normal subjects.
