Abstract

Objective To explore the value of visual P300 potentials in responsible appreciation of schizophrenia patients by judicial expertise. Methods Sixty-eight schizophrenia patients without responsible ability (group A) and 59 schizophrenia patients with limited responsible ability (group B) by judicial expertise and 58 healthy volunteers (group C) were enrolled in this study. They were given visual P300 potentials test. Results Compared to group C, latent periods of N1, N2, and P3 of P300 in groups A and B were significantly longer (P<0.01), and the amplitude of P3 decreased markedly (P<0.01). Compared to group B, latent periods of N1, N2, and P3 of P300 in group A were significantly longer, and amplitude of P3 decreased markedly (P<0.01). Conclusion Visual P300 potentials test has referential meaning in responsible appreciation of schizophrenia by judicial expertise, which needs confirmation by long follow-up.

Key words： judicial expertise; responsible ability; schizophrenia; visual P300 potentials
