Catholic University scientists uncover Parkinson's breakthrough
Intensive Exercise in early stages of Parkinson's found to slow disease progression.


In a groundbreaking discovery, a collaborative team of neuroscience researchers from the Catholic University, Rome Campus, and A. Gemelli IRCCS Polyclinic Foundation has made significant strides in understanding Parkinson's disease. The research indicates that regular and intensive exercise, when initiated early into a diagnosis, could potentially slow the progression of this debilitating condition. While the findings are currently in the animal testing phase, they offer hope for the development of non-drug treatments for Parkinson's disease. The study was published in the esteemed journal Science Advances, shedding light on a previously unknown mechanism that supports neuron survival and enhances brain plasticity.


Led by Professor Paolo Calabresi, a renowned expert in Neurology at the Catholic University and Director of the UOC Neurology at the University Polyclinic A. Gemelli IRCCS, the research team revealed the novel mechanism uncovered through their investigation. Professor Calabresi expressed his optimism, stating, "We have discovered a never observed mechanism, through which exercise performed in the early stages of the disease induces beneficial effects on movement control that may last over time even after training is suspended."


The researchers set out to explore the link between intensive exercise and the production of an essential growth factor known as brain-derived neurotrophic factor (BDNF). Previous data had suggested that intense physical activity could lead to increased BDNF production. To validate this connection, the team conducted tests involving an animal model of early-stage Parkinson's disease placed on a treadmill. The results were encouraging as they were able to confirm that higher levels of BDNF contributed to improved brain function and physical activity.


Parkinson's disease is characterized by the gradual spread of pathological alpha-synuclein aggregates throughout the brain, leading to the degradation of neurons responsible for motor function. This deterioration manifests in the physical tics associated with the illness. The treadmill experiments yielded crucial insights, as the researchers found that elevated BDNF production mitigated the spread of these aggregates. In essence, intensive exercise appeared to slow the degeneration of neurons while strengthening their structure and plasticity.


One of the most significant implications of this research is that the benefits of strenuous exercise extended beyond merely halting neuron degradation. The plasticity of the neurons themselves improved, suggesting that subjects might enjoy enhanced protection beyond the exercise period. Nevertheless, Professor Calabresi emphasized the need for further research before moving on to human trials. He expressed confidence that their findings would serve as a model to monitor the progression of Parkinson's disease during its early stages. In his study, he wrote, "Our research team is involved in a clinical trial to test whether intensive exercise can identify new markers to monitor the disease progression slowing in early-stage patients and the profile of the progression of the disease… This will allow us to identify molecular and cellular mechanisms underlying the observed beneficial effects."


While the discovery is promising, it is essential to underscore the need for cautious optimism and additional studies to establish the efficacy and safety of exercise as a potential treatment for Parkinson's disease. The path to translating these findings into meaningful therapeutic interventions for patients is likely to be complex, involving rigorous scrutiny and adherence to ethical guidelines.


As the scientific community and medical experts eagerly await the results of ongoing research, this breakthrough offers a glimmer of hope for individuals and families affected by Parkinson's disease. The possibility of non-drug interventions providing relief and improved quality of life for those grappling with this condition is a beacon of hope on the horizon.
