Effects of trauma-related audiovisual stimulation on cerebrospinal fluid norepinephrine and corticotropin-releasing hormone concentrations in post-traumatic stress disorder

Thomas D GeraciotiNosakhare N Ekhator


Although elevated concentrations of both corticotropin-releasing hormone (CRH) and norepinephrine are present in the cerebrospinal fluid (CSF) of patients with post-traumatic stress disorder (PTSD), the effects of exposure to traumatic stimuli on these stress-related hormones in CSF are unknown. A randomized, within-subject, controlled, cross-over design was used, in which patients with war-related PTSD underwent 6-h continuous lumbar CSF withdrawal on two occasions per patient (6-9 weeks apart). During one session the patients watched a 1-h film containing combat footage (traumatic film) and in the other a 1-h film on how to oil paint (neutral film). At 10-min intervals, we quantified CRH and norepinephrine in CSF, and ACTH and cortisol in plasma, before, during, and after symptom provocation. Subjective anxiety and mood were monitored using 100-mm visual analog scales. Blood pressure and heart rate were obtained every 10min from a left leg monitor. Eight of 10 patients completed two CSF withdrawal procedures each. A major drop in mood and increases in anxiety and blood pressure occurred during the traumatic relative to the neutral videotape. CSF norepinephrine rose during the traumatic film relative to the neutral videotape; ...Continue Reading
