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.
