“…In terms of non-motor symptoms, our study also showed a negative relationship between serum UA levels and depression score but not with cognitive score, similar to the recent study in de novo adjusted PD models [7,9]. These observations suggest that UA not only has a protective effect against dopaminergic cell loss but also against non-dopaminergic cells such as serotonergic neurons [5].…”

“…A reduction in the glomerular filtration rate can increase the level of serum UA and a recent meta-analysis indicated that low serum UA levels are associated with an increased risk and progression of PD [6]. A recent study also showed a negative relationship between UA levels and non-motor symptoms in de novo PD patients [7]. Although a relationship between UA levels and PD has been demonstrated, the association of UA and motor subtypes of PD has not been studied.…”

“…Thus, UA may play a different role in patients than in healthy individuals. In contrast, in drug‐naïve PD patients, lower UA levels have been associated with cardiovascular domains, as evaluated by NMSQuest (Moccia et al., 2014). Pan et al.…”

“…Moccia et al. (2014) reported that early‐stage, drug‐naïve PD patients with lower serum UA levels had higher scores in the attention/memory, cardiovascular, and sleep domains, as evaluated by NMSQuest. In MSA patients, no correlation has been found between serum UA levels at the initial visit and the mean rate of annual changes in the Unified MSA Rating Scale (Cao et al., 2013).…”

“…In detail, UA levels have been associated with specific NMS, such as attention/ memory, depression/anxiety, and cardiovascular. 117,120,121 The association with the impairment of attention/memory domains seems particularly promising since confirmed by different studies exploring cognitive function with comprehensive neuropsychological batteries. 122,123 Furthermore, a recent Phase 2 trial on the use of inosine in PD, a precursor of UA, showed a possible association between increased UA levels and mood disorders assessed with the Geriatric Depression Scale.…”
