title = "Nonmotor symptoms in healthy Ashkenazi Jewish carriers of the G2019S mutation in the LRRK2 gene",
abstract = "Background: 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. Methods: 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. Results: 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). Conclusions: 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.",
