Study Details

Study Description

Brief Summary

Parkinson's Disease (PD) is often accompanied by non-motor symptoms that make treatment more difficult. One such symptom is apathy (lack of motivation and emotion). There are no treatments for apathy in PD, and this remains a major unmet need in PD patients. One possible way to target apathy in PD patients is listening to music, which has been shown to help improve apathy in older adults. Little work has explored the mechanism in which music targets apathy. Thus, the goal of this study is to understand how music listening can impact the brain towards decreasing apathy in PD patients.

Detailed Description

Apathy is a common neuropsychiatric disturbance that manifests in approximately a quarter of patients in early stages of Parkinson's Disease (PD) and becomes more prevalent over disease progression and cognitive decline. Apathy in PD has been categorized as a distinct behavioural syndrome which can be differentiated from depression and anxiety, and is independently associated with lower functioning in daily life, decreased treatment response, and worse quality of life compared with PD patients without apathy. Characterized by a dysfunction in motivation, or lack of self-initiated goal-directed actions, apathy in PD has been hypothesized to stem from dysfunction in goal-directed reward-seeking networks that rely on dopaminergic transmission in the mesocorticolimbic and frontostriatal pathways, which includes the striatum (includes the nucleus accumbens, or NAc), prefrontal cortex (PFC), hippocampus, and amygdala. Pharmacological trials have attempted to target apathy through the neurotransmitter systems with limited success and sometimes adverse effects. The treatment of apathy remains a major unmet need in PD; thus, it is crucial to develop therapeutic interventions targeting apathy in PD and better understand the underlying mechanisms that may lead to apathy.

Evidence of the positive effects of music-based interventions (MBIs) in both healthy aging and clinical geriatric populations has been examined extensively across the literature. The positive effects of MBIs on alleviating apathy and increasing motivation have been reported in studies focusing on several clinical populations, such as dementia, autism spectrum disorder, and patients undergoing cardiac rehabilitation. A major gap in the MBI clinical trials literature is the lack of attention on the underlying mechanisms in which music can carry out its effects, especially regarding reward pathways. Dysfunction in the reward pathways, which involve the striatum, limbic system, and prefrontal cortices, underlie many disorders, symptoms, and syndromes, and elucidating the role of this underlying network with music is important towards understanding how music can mediate reward deficiencies, such as apathy. Understanding how music works to improve brain functioning is a key gap in understanding how to best inform the development of new therapies and interventions.

Recent work in functional, neurochemical, and pharmacological studies have helped elucidate the role of music in activating reward pathways. Namely, the nucleus accumbens (NAc) has been shown to be involved with processing peak emotionally arousing musical experiences, such as the "chills", and subjective valuations from music. Dopamine transmission in the ventral and dorsal striatum is implicated in regulating this process determined through positron emission tomography (PET) imaging. This work has established the role that the NAc and striatum, and dopaminergic transmission play in processing reward from music and its effects on aspects of cognition, such as motivation, learning, and memory. Thus, the effects of music may be able to mediate the underlying reward system that is compromised in PD patients.

More recently, connectivity between reward and auditory circuits, which include the superior temporal gyrus (STG), superior temporal sulcus (STS) and Heschl's gyrus (HG), have been implicated in musical reward processing and evaluation. No studies to date have observed the immediate and long-term effects of rewarding music on the implicated auditory-reward circuitry and action-oriented behaviour. Thus, this study aims to examine the immediate and longitudinal effects of participant-evaluated rewarding music on clinical apathy measures, connectivity in the auditory-reward networks, and effortful activity in PD patients with and without apathy.

Other Outcome Measures

  1. Clinical assessment for overall cognition - Montreal Cognitive Assessment (MoCA) [0 weeks (baseline)]

    The MoCA is a researcher-administered 30-item assessment covering 8 aspects of cognition: visuospatial/executive, naming, memory, attention, language, abstraction, delayed recall, and orientation. Scores range from 0-30. Higher scores indicate better cognition; lower scores indicate poorer cognition.

    The BDI is a self reported 21-question multiple-choice self-report inventory on a scale from 0-3. Scores range from 0-63. Higher scores indicate higher levels of depression; scores over 40 are considered as extreme depression. It will be used as a screening tool to observe any overlap between apathy and depression.

  3. Validated assessment of musical perception (contour subtest) - Montreal Battery of Evaluation of Amusia (MBEA); [0 weeks (baseline)]

    The Montreal Battery of Evaluation of Amusia (MBEA) measures level of general music perception for universal musical structures. This will be used to rule out any non-effects of the music intervention due to a deficit in musical perception abilities; the contour subtest will be used to evaluate this.

  4. Clinical assessment of overall reward/pleasure sensitivity - Snaith-Hamilton Pleasure Scale (SHAPS) [0 weeks (baseline)]

    The SHAPS will be used to compare with BMRQ to isolate for overall anhedonia/apathy versus music-specific apathy (Loui and Belfi, 2020). Higher scores correlate with higher apathy/less pleasure.
