Peter ForsterBasic Science, Major Depression, Psychobiology

That depression may be linked to alterations in glutamate circuits is suggested by the observation that ketamine (which is an NMDA glutamate receptor antagonist) may rapidly reverse depression in some patients. Depression has also been found to be associated in some people with various markers for inflammation (c reactive protein, tumor necrosis factor, interleukin 1 beta, and interleukin 6). As …

A New Model of Anxiety and Fear

Peter ForsterAnxiety, Psychobiology

We often tell our patients that the treatment of anxiety is primarily through psychotherapy, in contrast to the treatment of mood disorders which is often based on medications or brain stimulation.
