Acute cognitive effects of the hypocretin receptor antagonist almorexant relative to zolpidem and placebo: a randomized clinical trial.

Study Objectives: Hypnotic medications can adversely affect behavior during unanticipated awakenings during the night. Animals treated with the hypocretin (Hcrt) receptor antagonist almorexant (ALM) have less acute cognitive impairment compared to the GABAA receptor modulator zolpidem (ZOL). This study aimed to determine whether ALM produces less acute cognitive impairment than ZOL in human subjects.

Virtual reality exposure therapy for the treatment of posttraumatic stress disorder: a methodological review using CONSORT guidelines.

Context: Virtual reality exposure therapy (VRET) is an extension of traditional exposure therapy and has been used to treat a variety of anxiety disorders. VRET utilizes a computer-generated virtual environment to present fear-relevant stimuli. Recent studies have evaluated the use of VRET for treatment of PTSD; however, a systematic evaluation of the methodological quality of these studies has yet to be conducted.
