123. The Late Positive Potential Response to Olfactory Stimuli in Combat Veterans with Posttraumatic Stress Disorder

Article

This article examines evidence that olfaction plays a key role in emotional processing in PTSD. The current study examines pre- and post-treatment LPP amplitudes in response to olfactory stimuli in combat veterans with PTSD.

Abstract

A potential treatment moderator for PTSD is severity of emotional dysregulation. The late positive potential (LPP) amplitude from EEG has been used to assess individual differences in emotional reactivity. There is evidence that olfaction plays a key role in emotional processing in PTSD. The current study examines pre- and post-treatment LPP amplitudes in response to olfactory stimuli in combat veterans with PTSD.
