Neural substrates of speech disorders in Parkinson’s disease: A narrative review of the evidence from task-based and resting-state fMRI studies

Key Points

• Speech disorders are associated with specific neural substrates in parkinson's disease, impacting communication.
• Task-based fMRI studies reveal altered brain activity patterns, with significant implications for speech production.
• Resting-state fMRI assessments provide insights into connectivity changes in affected brain regions.
• The findings highlight the need for targeted interventions, as better understanding could improve therapeutic approaches.
