On the basis of her experiences in dealing with neuropsychiatric problems among victims of Boston's Cocoanut Grove fire, Dr. Adler distinguishes between 'fear neuroses' and 'conflict neuroses'—terms previously used by Symonds. The former are characterized by emotional disturbances and nightmares immediately after the trauma and show evidence of a psychological attempt to recapitulate the circumstances of the disastrous experience. In the 'conflict neuroses' the onset of symptoms occurs after a free interval and shows the obvious influence of old emotional problems. Dr. Adler also reports that no cases of (conversion) hysteria occurred among patients who had been hospitalized in contrast to such symptoms in unhospitalized cases and attributes this to the promotion of insight and understanding in the hospital. This report furnishes an interesting control study of traumatic neuroses developing after head injuries and battle experiences.
