Diagnosing PTSD: Lessons From Neuropsychology

Problematic diagnostic issues related to neurocognitive conditions have been well documented in research using neuropsychological instruments. However, due to the nature of differing assessment methods, these issues have not been as clearly established in the diagnostic assessment of psychiatric disorders that rely on self-report. Nonetheless, they appear relevant. This article summarizes diagnostic-related lessons learned based on clinical neuropsychological research and how they are applicable to the practice of diagnosing psychiatric conditions, post-traumatic stress disorder (PTSD) in particular. Ignoring these lessons raises serious risk for misdiagnosis, inappropriate treatment and services, and iatrogenic illness.
