摘要 目的对不同类型婴儿痉挛症的脑电图棘波分布特征进行分析,探讨不同病因的棘波特点。方法视频脑电图监测52例婴儿痉挛症患儿,分别计算各导联的棘波密度和相对棘波密度,并对不同病因的脑电图进行归纳。结果 52例婴儿痉挛症,36.5%的病例累及枕后颞区。40例症状性婴儿痉挛症,47.5%主要累及枕后颞区;12例隐源性婴儿痉挛症,8.3%主要累及枕区,两组间比较差异有统计学意义(P<0.05)。症状性婴儿痉挛症中,72.5%有围产期病因,其中55.2%主要累及枕后颞区。结论婴儿痉挛的脑电图在全导不对称、不同步的多棘慢波的基础上,常常伴有枕后颞区的局灶放电;症状性婴儿痉挛症比隐源性婴儿痉挛症更易出现枕后颞区的棘波放电,提示大脑发育过程的枕、后颞区可能更易受到各种病因的损害,并可能与症状性婴儿痉挛症的病理机制有关。
