目的/背景白天过度嗜睡(EDS)是一种常见的精神疾病,可以单独出现,也可以合并其他神经系统或精神疾病。我们对EDS发展的机制知之甚少,EDS患者的临床管理仍然是一个未满足的需求。在这项研究中,我们假设,丘脑多巴胺能功能将被改变EDS的受试者,我们试图调查这通过评估[123 I]FP-CIT单光子发射计算机断层扫描(SPECT)的数据,这是一个分子成像标记的多巴胺转运蛋白(DAT)Patients/MethodsWe进行了一项病例对照研究,使用人登记为健康受试者在帕金森氏病进展标志物倡议数据库。我们评估和比较半定量[123 I]FP-CIT-SPECT在两组21名健康受试者和无EDS,谁是匹配的年龄,性别,年的教育和快速眼动(REM)睡眠行为障碍(RBD)问卷scores.ResultsOur研究结果显示,增加丘脑DAT结合在EDS的人相比,匹配的健康受试者没有EDS。更高的丘脑DAT结合也与更差的EDS scores.ConclusionOur研究结果提供的证据表明,增加多巴胺能功能的丘脑可能介导过度的白天嗜睡在人类。
Objectives/BackgroundExcessive daytime sleepiness (EDS) is a common disorder, which can manifest in isolation or in combination with other neurological or psychiatric disorders. We know relatively little about the mechanisms underlying the development of EDS and the clinical management of patients with EDS remains an unmet need. In this study, we hypothesised that thalamic dopaminergic function would be altered in subjects with EDS and we sought to investigate this by assessing [123I]FP-CIT Single Photon Emission Computed Tomography (SPECT) data, which is a molecular imaging marker of dopamine transporter (DAT).Patients/MethodsWe performed a case–control study using people registered as healthy subjects in the Parkinson's Progression Markers Initiative database. We assessed and compared semi-quantified [123I]FP-CIT-SPECT in two groups of 21 healthy subjects with and without EDS, who were matched for age, gender, years of education and Rapid eyemovement (REM) sleep behaviour disorder (RBD) Questionnaire scores.ResultsOur findings show increased thalamic DAT binding in people with EDS compared to matched healthy subjects without EDS. Higher thalamic DAT binding also correlated with worse EDS scores.ConclusionOur findings provide evidence that increased dopaminergic function in the thalamus may mediate excessive daytime sleepiness in humans.
