RESUMO
Objective To examine the effect of risperidone on the mental symptoms after frontotemporal brain contu?sion. Methods Sixty cases with mental symptoms after frontotemporal brain contusion were recruited from Jan 2009 to Dec 2011 and were randomly divided into control group and treatment group. The patients in the control group were giv?en vitamin B1 60mg/d, while the patients in the treatment group were given risperidone 1mg/d. Both groups were treated for 1 month. Positive and negative symptom scale (PANSS) and symptom scale (TESS) were used to evaluate the efficacy and adverse reactions of treatment. Results The PANSS score was significantly lower in the treatment group than in con?trol group at 1, 2, 3 and 4 weeks following treatment(difference between groups:F=48.12 ,P<0.0001;Time difference:F=290.99 ,P<0.0001; Interaction between group and time: F=11.91,P<0.0001 ). After time-adjustment, the PANSS score was significantly lower in the treatment group than in control group at 2, 3 and 4 weeks following treatment. In the course of treatment, the patients in both groups had varying degrees of headache, nausea, weight gain and Beckoning. These side effects were alleviated through symptomatic treatment. Conclusion Risperidone can significantly improve psy?chiatric symptoms in patients with frontotemporal brain contusion with satisfactory safety.
