Psychotic Disorder Due to Traumatic Brain Injury: Analysis of Case Studies in the Literature

The present study utilized methodology from a previous descriptive study that analyzed case studies of psychotic disorder due to traumatic brain injury (PD-TBI) reported in psychiatry and neurology journals. The purpose was to replicate findings from the PD-TBI literature and to elucidate a pattern of characteristics that would differentiate PD-TBI from schizophrenia. The findings supported both objectives. PD-TBI data were highly consistent with previous studies: PD-TBI differed from schizophrenia in showing more focal frontal and temporal abnormalities on neurological studies and a lower rate of negative symptoms. The authors discuss implications of these findings for conceptualizing psychosis as a neurobiological syndrome.

Psychotic disorder caused by traumatic brain injury.

Psychosis is a rare and severe sequela of traumatic brain injury (TBI). This article assists clinicians in differential diagnosis by providing literature-based guidance with regard to use of the Diagnostic and Statistical Manual for Mental Disorders 5 criteria for this condition. This article also describes potential relationships between TBI and the development of a psychosis within the conceptualization of psychosis as a neurobehavioral syndrome.

Is psychosis a neurobiological syndrome

Objective: To describe theoretical weaknesses in the DSM-IV criteria for psychotic disorders and to argue that schizophrenia-like psychosis is a neurobiological syndrome similar to aphasia or apraxia. Method: We outline the criteria for the concept of neurobiological syndrome and present supporting evidence for schizophrenia-like psychosis as a neurobiological syndrome. Results: There is evidence in the literature to support the hypothesis that schizophrenia-like psychosis is a neurobiological syndrome. Conclusion: Conceptualizing schizophrenia-like psychosis as a neurobiological syndrome has important implications for both clinicians and researchers.

Dementia screening: can a second administration reduce the number of false positives?

OBJECTIVE Early diagnosis of dementia is important for medical treatment and quality-of-life interventions. The authors examine whether administering a second cognitive screening after a poor initial score can improve the accuracy of diagnosis. Of particular interest is reducing false positives that may generate an unnecessary referral for a dementia work-up. METHODS A group of 389 Japanese men from the Honolulu-Asia Aging Study were administered the Cognitive Assessment Screening Instrument (CASI) twice within a 2-month period. A small sample received a follow-up CASI 3 years later. RESULTS Administration of a second CASI reduced the false-positive rate by 16.1% in the total sample and 20.2% in those suspected of having mild dementia. The negative predictive value for the second administration was 80% for the entire sample and 82.6% for those suspected of having mild dementia. CONCLUSION Administration of a second cognitive screening in patients initially scoring in the dementia range can significantly reduce the number of false positives for dementia. This technique may be useful to managed-care companies who aim to reduce unnecessary costs in medical care.
