An Open-Label Trial of Memantine for Cognitive Impairment in Patients With Post-Traumatic Stress Disorder

Summary

Twenty six veterans with PTSD and cognitive impairment received 16 weeks of memantine in an open label fashion. Cognition was assessed using the Spatial Span, Logical Memory I, and Letter-Number Sequencing subtests of the Wechsler Memory Scale III (Third edition) and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). RBANS measures attention, language, visuospatial skills, and immediate and delayed memories. The Clinician Administered PTSD Scale (CAPS), Hamilton Depression Scale (HAM-D), Hamilton Anxiety Scale (HAM-A), Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), and Sheehan Disability Scale (SDS) were used to assess improvement in PTSD symptoms, as secondary outcome measures.
