Reliability of post-mortem psychiatric diagnosis for neuroscience research

Objective: The validity of post-mortem human brain research relies upon accurate clinical and psychopathological diagnosis. Current literature indicates few instances where standardized diagnostic assessment tools such as the Diagnostic Instrument for Brain Studies have been utilized. The primary aim of the present study was to investigate the degree of concordance between predominant ante-mortem psychiatric diagnoses indicated in medical records, and post-mortem diagnoses derived through structured diagnostic instruments such as the Diagnostic Instrument for Brain Studies and the Item Group Checklist of the Schedules for Clinical Assessment in Neuropsychiatry.Methods: Fifty-eight subjects from the New South Wales Tissue Resource Centre, assigned a clinical psychiatric diagnosis after death, were included in the study. The predominant ante-mortem diagnosis of each case was compared to the corresponding post-mortem diagnosis obtained through structured case reviews to which either the Diagnostic Instrument...
