In this consecutive series of 30 patients with PD on LCIG infusion, with early and continuous vitamins B integration, we observed a low rate (19%) of new onset peripheral polyneuropathy that remained stable after long-term follow-up. Larger studies, controlled, with blinded evaluation, are needed to confirm these findings.

Background and purpose During the first phase of the COVID‐19 pandemic, a lockdown was imposed in Italy. The aim of this study was to investigate the perceptions, feelings and unmet needs of Parkinson's disease (PD) patients who experienced the 2‐month lockdown in a “red zone” in the northern part of Italy during the COVID‐19 outbreak. Methods The study had a descriptive design that used a cross‐sectional online survey which included open‐ended questions to elicit responses on the participant's feelings concerning their risk of contracting coronavirus, how their physical activity had changed, and their personal needs, dictated by their condition, which were not met in this pandemic period as compared to previous periods. Demographic data were analysed using descriptive frequencies, while the open‐ended questions were analysed using thematic framework analysis. Results The study included 103 participants (63 men/40 women [61.17 vs. 38.83%]). Framework analysis led to the identification of four main themes: (i) fearing the risk of contracting coronavirus; (ii) reduction of physical activity; (iii) perception of the risk of not being able to access outpatient clinics or support services; and (iv) negative experiences of the important reduction in socialization. The perceptions of unmet needs appeared to be greater than the actual experience, particularly for the reduction in physical activity and the interruption of contacts with the neurologist and other specialists. Conclusions This study highlights how perceptions and actual experience shape the meaning of living with PD during the pandemic. Worth noting is the divergence between perceptions and real impact in some aspects of the COVID‐19 outbreak.

This review summarizes the most recent, relevant advances in neuroimaging technology in Parkinson's disease. In particular, the combination of different imaging techniques seems promising to maximize the scope of future work, which should, among others, aim at identifying the best imaging marker of disease progression.
