A new study has been published in the journal Antioxidants and Redox Signaling by Dr. Bobby Thomas who is a neuroscientist with the Medical College of Georgia at Georgia Health Sciences University. His study shows that NRF2 activation in an animal model boosts the cells production of its own antioxidant enzymes and manages inflammation at the same time. This helps the cells recover from the damaging effects of high oxidative stress associated with Parkinson's disease.
More specifically, Thomas and his fellow researchers proved that they were able to block the death of dopamine-producing brain cells that occurs in Parkinson's by activating Nrf2, a natural antioxidant and inflammation fighter.
Parkinson's Disease Symptoms Include:
- Tremors
- Slowed movement (bradykinesia).
- Rigid muscles/Muscle stiffness
- Loss of automatic movements including blinking, smiling or swinging your arms when you walk.
- Speech changes
