Dementia with Lewy bodies (DLB) is a neurodegenerative disease characterized by cognitive, behavioral and motor symptoms and has a more challenging clinical management and poorer prognosis compared to other forms of dementia. The experience of lockdown leads to negative psychological outcomes for fragile people such as elderly with dementia, particularly for DLB, causing a worsening of cognitive and neuropsychiatric symptoms. Since an individual's feeling of time passage is strongly related to their cognitive and emotional state, it is conceivable to expect alterations of this construct in people with DLB during such a difficult period. We therefore assessed the subjective experience of the passage of time for present and past time intervals (Subjective Time Questionnaire, STQ) during the lockdown due to coronavirus disease (COVID-19) in 22 patients with DLB (17 of which were re-tested in a post-lockdown period) and compared their experience with that of 14 caregivers with similar age. Patients showed a significantly slower perception of present and past time spent under lockdown restrictions. We argue that these alterations might be related to the distinctive features of DLB and their exacerbation recorded by the patients' caregivers during the period of lockdown, though our results show that the patients' experience of time passage in a post-lockdown period remained similarly slow. Overall, we show an impairment of the subjective perception of time passage in DLB tested during the COVID-19 lockdown.

路易体痴呆（DLB）是一种神经退行性疾病，其特征为认知、行为和运动症状，与其他形式的痴呆相比，临床管理更具挑战性，预后更差。封锁经历给痴呆老年人等脆弱人群带来负面心理影响，尤其是对DLB患者，会导致认知和神经精神症状恶化。由于个体对时间流逝的感觉与其认知和情绪状态密切相关，因此可以想象，在这样一个困难时期，DLB患者的这种感觉会发生改变。因此，我们评估了22例DLB患者在因冠状病毒病（COVID-19）实施封锁期间对当前和过去时间间隔的主观时间体验（主观时间问卷，STQ），其中17例患者在封锁后进行了重新测试，并将他们的体验与14名年龄相仿的照料者进行了比较。患者对封锁限制下当前和过去时间的感知明显更慢。我们认为，这些改变可能与DLB的独特特征及其在封锁期间照料者记录的症状加重有关，尽管我们的结果显示，患者在封锁后时期对时间流逝的体验仍然同样缓慢。总体而言，我们显示了在COVID-19封锁期间测试的DLB患者主观时间流逝感知受损。
