Autor: Saurabh Shaw, Braeden Terpou, Maria Densmore, Jean Theberge, Paul Frewen, Margaret McKinnon, Ruth Lanius

Background: In 2012, a dissociative subtype of post-traumatic stress disorder (PTSD) was introduced into the DSM based on emerging clinical and neurobiological evidence of a distinct PTSD phenotype characterized by trauma-related dissociation. Ten ye

Abstract Myo-inositol is mainly found in astroglia and its levels has been shown to be reduced in the anterior cingulate cortex (ACC) of patients with schizophrenia. We investigate the status of astroglial integrity indexed by ACC myo-inositol at the
