Characteristics and correlative factors of musical emotion recognition in patients with Parkinson's disease / 中华神经科杂志

ABSTRACT

Objective To investigate emotion recognition in music in patients with idiopathic Parkinson's disease (PD),and to further explore its relationship with executive function and related factors.Methods Twenty-four PD patients enrolled from the Department of Neurology,Beijing Hospital between January and June 2014 and 24 matched healthy controls were tested using 24 musical excerpts that expressed happiness,sadness,fear or anger.The two groups were tested for executive function using a simplified trail making test and a clock drawing test.All the patients were rated on the Hoehn-Yahr stage,the Unified Parkinson' s Disease Rating Scale (UPDRS) Ⅲ,the Hamilton Rating Scale for Anxiety (HAMA) and the Hamilton Rating Scale for Depression (HAMD).Results In trail making test,PD patients worked slower ((51.58 ±33.14) s) than controls ((34.46 ± 19.64) s) (t =2.178,P =0.036).PD patients got more errors (0 (QL =0,QU =2.5)) than controls (0 (QL =0,QU =0);Z=-2.372,P =0.018).In clock drawing test,PD patients got lower score (2.63 ±0.65) than controls (2.96 ±0.20)(t =-2.407,P =0.023).The difference between two groups was not statistically significant in the recognition of happy,sad,fear or anger music (all P ＞ 0.05).In PD group,the scores of the recognition of happy,sad music and the total score of musical emotion recognition were associated with the time of trail making test (r =-0.560,-0.572,-0.530,P =0.004,0.003,0.008),while not related to age,disease duration,education duration,the scores of Minimum Mental State Examination,the scores of UPDRS Ⅲ,Hoehn-Yahr stage,the scores of HAMA,the scores of HAMD,LDE,the scores of clock drawing test or musical background (all P ＞ 0.05).Conclusions PD patients are not impaired in emotion recognition in music in this study.The relationship between musical emotion recognition and executive function is unclear.
