Neurologists in Brazil are highlighting the growing global impact of Parkinson's disease and emerging treatments to restore brain function [1].

As the prevalence of this condition rises faster than other neurological disorders, understanding the mechanisms of dopamine loss is critical for developing effective interventions [1].

During a broadcast of the program “Sinais Vitais,” host Dr. Roberto Kalil and neurologists Dr. Roberta Saba and Dr. Rubens Cury discussed how the disease alters the brain [1]. The specialists said that approximately 11.8 million people worldwide are living with Parkinson's [1]. In Brazil, the number of affected individuals is approximately 500,000 [1].

The experts said that the disease primarily targets the production of dopamine, a neurotransmitter essential for controlling movement and coordination. To combat this, researchers are exploring cell-based therapies designed to restore dopamine levels in the brain [3].

Beyond medical interventions, the specialists emphasized the role of physical activity. Research conducted at the Federal University of Rio Grande do Norte (UFRN) and the Federal University of Paraná (UFPR), in partnership with UK institutions, suggests that exercise can make the brain more efficient [2]. Specifically, activities such as cycling may provide significant benefits for those living with the condition [2].

These combined approaches — utilizing both cellular medicine and lifestyle changes — aim to mitigate the progressive nature of the disease and improve the quality of life for patients [1], [3].

“Approximately 11.8 million people worldwide are living with Parkinson's.”

The focus on both cellular restoration and physical exercise indicates a shift toward multimodal treatment for Parkinson's. By combining biological interventions to replace lost neurotransmitters with lifestyle habits that optimize existing brain efficiency, clinicians aim to slow the functional decline associated with the disease's increasing global prevalence.
