Parkinson’s Disease, Intense Exercise Helps To Keep The Disease At Bay


Neuroscientists from the Faculty of Medicine of the Catholic University, Rome Campus, and the A. Gemelli IRCCS Polyclinic Foundation found that intensive exercise could slow the course of Parkinson’s disease and described the biological mechanisms. The finding could pave the way for new non-drug approaches.

The study “Intensive exercise ameliorates motor and cognitive symptoms in experimental Parkinson’s disease by restoring striatal synaptic plasticity” is published in the journal Science Advances. The research was led by Catholic University, Rome Campus and A. Gemelli IRCCS Polyclinic Foundation, in collaboration with several research institutes: the San Raffaele Telematic University Rome, CNR, TIGEM, University of Milan, and IRCCS San Raffaele, Rome.

The research was funded by the Fresco Parkinson Institute to New York University School of Medicine and The Marlene and Paolo Fresco Institute for Parkinson’s and Movement Disorders, the Ministry of Health and MIUR (both related to the PRIN 2017 call and CNR-MUR calls, two different grants). It identified a new mechanism responsible for the positive effects of exercise on brain plasticity.

The corresponding author, Full Professor of Neurology at the Catholic University and director of the UOC Neurology at the University Polyclinic A. Gemelli IRCCS Paolo Calabresi, said: “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”.

“In the future, it would be possible to identify new therapeutic targets and functional markers to be considered for developing non-drug treatments to be adopted in combination with current drug therapies”, he added.

Previous work has shown that intensive physical activity is associated with increased production of a critical growth factor, the brain-derived neurotrophic factor (BDNF).

The authors were able to reproduce this phenomenon in response to a four-week treadmill training protocol in an animal model of early-stage Parkinson’s disease, and to demonstrate, for the first time, how this neurotrophic factor determines the beneficial effects of physical activity in the brain.
