原发性震颤患者的非运动症状

目的 研究原发性震颤(essential tremor,ET)患者嗅觉障碍等非运动症状的发生情况.方法 对62例ET患者应用震颤评分量表(Falm-Tolosa-Matin Tremor Rating Scale,TRS)、帕金森病非运动症状30问卷量表(Parkinson's disease non-motor symptoms questionnaire,NMS Quest)和MMSE进行评分,T&T标准嗅觉测试液检测嗅觉功能,并与60名健康体检者进行对照.结果 ET患者的嗅觉障碍发生率为51.6%(32/62),明显高于健康对照组(30.0%,18/60,x~2=12.371,P<0.05);平均每例ET患者出现5项左右不同的非运动症状,以对近期发生的事情记忆有困难或忘记做一些事情、嗅觉障碍、令人紧张或害怕的梦或生动梦境的发生率较高.嗅觉障碍等非运动症状的发生与ET患者的病程、病情严重程度、治疗与否没有明显的相关性.结论 除姿势性震颤或动作性震颤外,ET患者还会出现嗅觉障碍等非运动症状,需要全面认识和及时干预.

Clinical study on non-motor symptoms of essential tremor

Objective To survey the prevalence, distribution of non-motor symptoms (NMS) in essential tremor (ET) and the relationship with disease severity and duration.Methods Fahn-Tolosa-Matin Tremor Rating Scale (TRS) was used to assess motor symptoms in 62 patients with ET.The Parkinson's disease (PD) NMS Questionnaire and T&T olfacmeter and Mini-mental State Examination (MMSE) were used to explore non-motor symptoms in ET patients.Results In ET, a range of NMS occurred across all disease stages.More than half patients (51.6%, 32/62) had olfactory dysfunction,significantly higher than the healthy control group (30.0%, 18/60, x~2=12.371, P<0.05).A third had hyposmia.16.1% had partial olfactory loss.Each ET patient had 5 different NMS on average.Seven NMS were more common in ET patients than in control, including remembering, olfactory dysfunction, intense vivid dreams, anhedonia, depression, anxiety, sleep disorders.The incidences of remembering, olfactory dysfunction,intense vivid dreams were 58.1% (36/62),51.6% (32/62),48.4% (30/62), ranked top 3 in ET patients.Olfaction had inverse correlation with age, while there was a negative correlation between NMS score and TRS score, gender, disease duration and weather to be treated.Conclusion Besides posture tremor and kinetic tremor,NMS occur in ET,and should be well recognized and treated.
