Targeting neuroendocrine abnormalities in Parkinson's disease with exercise

Area of Science:

• Neurobiology
• Endocrinology
• Gerontology

Background:

• Parkinson's Disease (PD) is a common neurodegenerative disorder with no current disease-modifying treatments.
• The underlying pathophysiology of PD involves multiple system dysfunction and remains incompletely understood.
• Emerging evidence suggests exercise offers symptomatic relief and potential neuroprotection in PD patients.

Purpose of the Study:

• To review the mechanistic pathways through which exercise influences the neuroendocrine system in Parkinson's Disease.
• To explore the role of specific hormones (cortisol, melatonin, insulin, klotho, vitamin D) in exercise-mediated benefits for PD.
• To identify potential biomarkers for tracking exercise effects and patient-induced disease control in PD.

Main Methods:

• Literature review focusing on exercise, neuroendocrinology, and Parkinson's Disease.
• Analysis of studies investigating hormonal regulation by exercise in the context of PD.
• Synthesis of evidence linking specific hormones to non-motor symptoms of PD.

Main Results:

• Exercise modulates the neuroendocrine system, impacting stress response, homeostasis, and resilience.
• Hormones such as cortisol, melatonin, insulin, klotho, and vitamin D are linked to non-motor PD symptoms (mood, cognition, sleep).
• These hormones show potential as biomarkers for evaluating exercise interventions in PD clinical trials.

Conclusions:

• Exercise influences the neuroendocrine system, offering a potential avenue for managing Parkinson's Disease.
• Specific hormones regulated by exercise may serve as biomarkers for treatment efficacy.
• Patients may gain behavioral control over aspects of their PD through exercise-induced hormonal changes.
