研究问题
Although this phenomenon has been studied for decades, and multiple factors have been proposed to correlate with sleep benefit in earlier investigations, these associations remain controversial [18].
方法
Patients with clinically diagnosed early‑onset or familial parkinsonism who underwent genetic testing at the Department of Neurology, the Hebei Medical University Third Hospital between January 1, 2016 and June 30, 2025, and who had not received anti‑parkinsonian treatment were retrospectively enrolled.；Inclusion criteria: Patients presenting with parkinsonism should fulfill one of the following conditions: age at onset ≤50 years, or age at onset ≥50 years with a positive family history (i.e., at least one first or second degree relative diagnosed with Parkinson’s disease or manifesting parkinsonism), together with a favorable/partial response to levodopa benserazide (≥15% improvement in MDS UPDRS III motor score) [19].；Exclusion criteria: Patients with identifiable etiologies underlying secondary parkinsonism were excluded, including those with exposure to specific medications (e.g., chlorpromazine, haloperidol, risperidone, olanzapine, metoclopramide, flunarizine, cinnarizine); toxin exposure (e.g., carbon monoxide, manganese, pesticides, organic solvents); recurrent stroke;…
核心结论
Of note, the improvement rate was between 15% and 30% in Patient 9 during the levodopa challenge test, whereas all other patients in this cohort achieved an improvement rate >30%. ‖ 结论：Thus, distinguishing JPD from DRD based on atypical symptoms can be challenging.
局限
It is possible that such phenotypic heterogeneity is attributable to differential functional impairment.；Thus, the influencing factors and mechanisms underlying sleep benefit in untreated hereditary parkinsonism warrant further investigation.；Furthermore, it remains unclear whether this phenotype represents a preclinical or early stage of PD, which warrants long-term clinical follow-up.

本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
