The characteristical and clinical value of Somatosensory Evoked Potential and event?related potential P300 in Patients With Juvenile Myoclonic Epilepsy
摘要
Abstract
Objective To explore the characteristic and clinical value of Somatosensory Evoked Potential SEP and event?related potential P300 in patients with Juvenile Myoclonic Epilepsy (JME), trying to provide neuroelectrophysiological evidence for the pathogenesis, diagnosis and antiepileptic drug efficacy of this disease . Methods 28 patients with JME and 30 healthy controls were enrolled in the research. They were applied the SEP and P300 before and after one year treatment. Results (1) The amplitude of SEP in patients with JME was significantly higher than those in the control group(P=0.000), the abnormal rate was 75%(21/28), while the latency of SEP was no significant difference (P>0.05); The latency of P300 in patients with JME was significantly longer (P = 0.000), 2 out of 28 cases were poorly differentiated, 9 cases were longer (11/28, 39%), while the P300 amplitude was no significant difference(P=0.110). (2) After treatment, the amplitude of SEP was significantly lower (P<0.05), the latency of P300 was significantly shorter (P=0.001). (3) The amplitude of SEP had a positively linear relationship with the latency of P300 (r = 0.818, P = 0.000). Conclusions The SEP amplitude was significantly higher in patients with JME, often accompanied by a huge SEP, so SEP can provide electrophysiological evidence for the pathogenesis and diagnosis of this disease.And P300 may give a chance to find the subclinical cognitive abnormalities and to intervent it early. The SEP had a positively linear relationship with the P300, simultaneously dynamic monitoring the change of SEP amplitude and P300 latency may become an objective evaluation for the antiepileptic drug efficacy.关键词
