兔唇综合征系神经阻滞剂所诱发的一种迟发性锥体外系副作用,由酷似兔的下颌运动,快速而有节律地细微震颤组成。与迟发性运动障碍时的口舌异常运动不同,本综合征用抗帕金森药物治疗可获得改善。兔唇综合征相对少见,有关其流行病学研究尚未有公开报道。为此作者对266例(男女各133例)住院精神病人兔唇综合征的发病率进行了调查。 Rabbit lip syndrome is a late-onset extrapyramidal side-effect induced by neuroleptics and is composed of a mandibular jerk that resembles a rabbit, and a fast and rhythmic subtle tremor. Unlike tachypnea in tardive dyskinesia, this syndrome can be ameliorated with anti-parkinsonian medications. Rabbit lip syndrome is relatively rare, its epidemiological studies have not been publicly reported. To this end, the authors investigated the incidence of rabbit’s lip syndrome in 266 inpatients (133 male and female) inpatient psychiatric patients.
