Prevalence and related risk factors of minor hallucinations in newly diagnosed Parkinson's disease patients / 临床神经病学杂志

ABSTRACT

Objective To screen the prevalence and related risk factors of minor hallucinations(MH)in newly diagnosed Parkinson's disease(PD).Methods From November 2018 to December 2022,274 newly diagnosed patients with untreated PD were enrolled in the PD Clinic of Brain Hospital Affiliated to Nanjing Medical University.According to the score of item 2 of the unified PD rating scale Ⅰ(UPDRSⅠ),the PD patients with MH were selected(MH group,score≥2).The patients matched in age,sex,education and course of disease level were screened in non-MH PD patients(NMH group,score = 0).Cognitive function,depressive symptoms,anxiety symptoms,sleep quality,non-motor symptoms,rapid eye movement sleep disorder(RBD)symptoms,activities of daily life,motor function and disease severity were evaluated with appropriate scales.The differences between two groups were compared,and the risk factors of MH in PD patients were analyzed by univariate and multivariate progressive Logistic regression.Results Among the 274 newly diagnosed PD patients,11 cases(4.01%)had MH.Compared with those in NMH group(22 cases),MH group had higher Hamilton depression scale(HAMD)scores,higher Hamilton anxiety scale(HAMA)scores,higher PD non motor symptoms(PDNMS)scores and higher RBD scores(all P＜0.05).Univariate Logistic regression analysis showed that high HAMD scores,high HAMA scores,high PDNMS scores and high RBD scores were risk factors for MH in PD patients(all P＜0.05).Multivariate Logistic regression analysis showed that high HAMD score(OR =1.182,95%CI:1.004-1.392,P =0.045)and high RBD score(OR =4.448,95%CI:1.066-18.557,P =0.041)were independent risk factors for MH in PD patients.Conclusions MH may occur in newly diagnosed PD patients with probability.Depression and RBD are independent risk factors for MH in PD patients.Attention should be paid to screening patients like this and early intervention measures should be taken.
