Repeated intravenous infusions of ketamine: Neurocognition in patients with anxious and nonanxious treatment-resistant depression

Recent studies have suggested that neurocognition is changed after repeated infusions of ketamine in patients with treatment-resistant depression (TRD). The objective of this study was to investigate whether differences existed in the neurocognitive effect of six ketamine infusions in patients with anxious and nonanxious TRD and to determine the association between baseline neurocognition and changes in symptoms after the infusions.Patients with...
