AimsLongitudinal studies addressing the predictive value of brain network connectivity in PD hallucinations are lacking. This study investigated whether functional connectivity markers could predict PD hallucinations independently of clinical markers.MethodsThis study used data from the Parkinson's Progression Marker Initiative, a longitudinal multicenter study that aims to identify biomarkers of PD progression. One hundred and three newly diagnosed PD patients (mean age 63.10 ± 9.70 years, 65 males) underwent clinical assessments and functional MRI scanning at baseline. Independent component analysis was used to explore intra-network and inter-network functional connectivity differences between PD patients who developed hallucinations and those who did not during the 2-year follow-up.ResultsTwenty patients developed hallucinations during the follow-up. At baseline, significantly decreased connectivity within the dorsal attention network (t = -6.65 ~ -4.90, p ConclusionsThe findings provide evidence that disrupted brain network connectivity is associated with a greater risk of future hallucinations in PD. This may aid in the early identification of PD patients at risk of hallucinations and provide a basis for the development of new therapies.
