INTRODUCTION: the relationship between laterality and asymmetry of @entity191 and @entity66 has been studied mainly from the perspective of cognitive functions, and the few studies that have included other symptoms have mixed reports. The relationship between non-motor symptoms and the type of onset of the disease has not been studied in detail. OBJECTIVE: to analyse the association between the side and type of motor onset and the prevalence of non-motor symptoms. @entity1 AND METHODS: we included 232 @entity1 diagnosed with @entity191 . Type of onset and the side initially affected were documented. The presence of non-motor symptoms was determined by applying the non-motor symptom questionnaire (NMSQuest). RESULTS: when analysing the side of onset and presence of each non-motor symptom explored, statistically significant differences were found in the frequency of @entity1833 (P=0.04) and @entity25 (P<0.01) in subjects with right side onset. The motor type of onset differences were not statistically significant. CONCLUSIONS: subjects with right side onset seem to have a higher risk of having @entity1833 and @entity25 . These symptoms should be intentionally sought in order to provide treatment and improve the @entity1 's quality of life.
