Abstract

Selective impairment of emotion recognition through music in Parkinson's disease: does it suggest the existence of different networks for music and speech prosody processing?

Highlights

The main hallmark of Parkinson’s disease (PD) are its motor symptoms, such as bradykinesia, resting tremor, postural instability, and rigidity, it has been increasingly recognized that such disease constitutes, a complex degenerative process which presents a variety of different clinical manifestations
Motivated by such increased attention to non-motor symptoms PD, and with basis on previous physiological studies which have demonstrated that the perception of music rhythm and beat is mediated mainly by the basal ganglia (Grahn, 2009), several recent studies have investigated the effects of PD over music perception
Other previous investigations had already demonstrated that a dysfunction in the dopaminergic system may only partially explain the observed impairment in emotion recognition through facial expressions in patients with PD (Bediou et al, 2012), as the treatment with levodopa did not significantly modify such deficit

Summary

Introduction

The main hallmark of Parkinson’s disease (PD) are its motor symptoms, such as bradykinesia, resting tremor, postural instability, and rigidity, it has been increasingly recognized that such disease constitutes, a complex degenerative process which presents a variety of different clinical manifestations. Motivated by such increased attention to non-motor symptoms PD, and with basis on previous physiological studies which have demonstrated that the perception of music rhythm and beat is mediated mainly by the basal ganglia (the major anatomical complex involved in the etiology of PD) (Grahn, 2009), several recent studies have investigated the effects of PD over music perception.
