The asymptomatic carriers of the Leucine rich repeat kinase 2 (LRRK2) G2019S mutation represent a population at risk for developing PD. The aim of this study was to assess differences in nonmotor symptoms between nonmanifesting carriers and noncarriers of the G2019S mutation.
Two hundred fifty-three subjects participated in this observational cross-sectional multicenter study. Standard questionnaires assessing anxiety, depression, cognition, smell, nonmotor symptoms, and rapid eye movement (REM) sleep behavior were administered. Analyses were adjusted for age, sex, family relations, education, and site.
One hundred thirty-four carriers were identified. Carriers had higher nonmotor symptoms score on the Nonmotor symptoms (NMS) questionnaire (P = 0.02). These findings were amplified in carriers older than age 50 y, with higher nonmotor symptoms scores and trait anxiety scores (P < 0.03).
In this cross-section study, carriers of the G2019S LRRK2 mutation endorsed subtle nonmotor symptoms. Whether these are early features of PD will require a longitudinal study. © 2015 International Parkinson and Movement Disorder Society.
富含亮氨酸重复激酶2(LRRK2)基因G2019S突变的无症状携带者是患帕金森病(PD)的高危人群。本研究旨在评估G2019S突变的未发病携带者与非携带者之间非运动症状的差异。
253名受试者参与了这项观察性横断面多中心研究。使用标准问卷评估焦虑、抑郁、认知、嗅觉、非运动症状和快速眼动(REM)睡眠行为。分析对年龄、性别、家庭关系、教育程度和研究地点进行了校正。
共识别出134名携带者。携带者在非运动症状(NMS)问卷上的非运动症状得分更高(P = 0.02)。这些发现在年龄大于50岁的携带者中更为明显,其非运动症状得分和特质焦虑得分更高(P < 0.03)。
在这项横断面研究中,LRRK2基因G2019S突变的携带者存在轻微的非运动症状。这些症状是否为PD的早期特征需要进行纵向研究。© 2015国际帕金森病和运动障碍协会
