Correlative factors for organic psychotic symptoms in patients following traumatic brain injury / 法医学杂志

OBJECTIVE@#To investigate the correlative factors for organic psychotic symptoms following traumatic brain injury (TBI).@*METHODS@#In the current study, 391 subjects who had undergone forensic identification of the organic mental disorders due to TBI were included, both the demographic and post-traumatic information collected. The relevant data were statistically analyzed in those confirmed as organic psychotic syndrome according to Chinese Classification of Mental Disorders 3rd version (CCMD-3).@*RESULTS@#Fifty-two subjects (13.3%) were identified as organic psychotic symptoms. The chi-square test showed that the detectable organic psychotic symptoms were associated with the marriage status, damage nature, injury severity and treatment, and the multivariate logistic regression analysis revealed good fitness of treatment and injury severity with the regression model (OR = 0.044, 95% CI: 0.017-0.114; OR = 2.145, 95% CI: 1.201-3.832, respectively).@*CONCLUSION@#The risks of organic psychotic symptoms following TBI can be involved in the alternative of craniotomy for the cases with trauma and moderate brain injury.

Evaluating on recognition impairment after traumatic brain injury with WCST / 法医学杂志

OBJECTIVE@#To explore the value of Wisconsin Card Sorting Test (WCST) in evaluating the recognition impairment after traumatic brain injury (TB1).@*METHODS@#WCST and Wechsler Adult Intelligence Scale Revised in China (WAIS-RC) were adopted to assess the cognitive function in 186 patients with brain injury (experimental group) and 180 healthy volunteers (control group), respectively. The cognition between the experimental group and the control group was compared. The correlation between WCST and IQ was analyzed. The correlation between age, education level, the severity of TBI and the executive function were also analyzed.@*RESULTS@#(1) The performances of WAIS-RC and WCST in the experimental group were significantly worse than that of the control group. (2) There were significantly negative correlation between the performance of total errors, percentage of preservative errors, percentage of random errors, response number on first category and IQ (P < 0.05). While there were significantly positive correlation between the categories completed, percentage of conceptual level and IQ (P < 0.05). (3) There was significantly negative correlation between percentage of conceptual level and the severity of TBI. While there were significantly positive correlation between percentage of preservative errors, percentage of random errors, response number on first category and the severity of TBI.@*CONCLUSION@#WCST could be an important method in evaluating cognition of patients with brain injury.
