Abstract
Although determination of diagnosis of cognitive impairments constitutes one of the core objectives of forensic neuropsychological assessment, the diagnostic criteria for cognitive disorders provided by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR, American Psychiatric Association 2000) have been of low internal and external validity and limited utility. This paper reviews the evolution of diagnosis of cognitive disorders from current DSM-IV-TR to the proposed DSM-V (American Psychiatric Association 2010). The conceptual framework is tracked, along with the body of literature associated with the DSM-V proposal on Minor and Major Neurocognitive Disorders. The quality of evidence for internal and external validity is reviewed, as well as the fairness and utility of newly proposed diagnoses from both clinical and forensic perspectives. Significant conceptual, evidentiary, psychometric, assessment, and practical questions are raised related to the new classification, and recommendations are offered for improvement to the proposal of the DSM-V Work Group on Neurocognitive Disorders.
