Researchers report six minutes of high-intensity exercise on a regular basis can slow brain aging and delay the onset of neurodegenerative diseases such as Alzheimer's and Parkinson's disease. High-intensity exercise increases the production of BDNF, a protein implicated in memory, learning, and brain plasticity, which could protect the brain from age-related cognitive decline.
Low-intensity exercise triggers brain networks associated with cognitive control and attention processing, while high-intensity exercise activates networks involved in emotional processing.
Exercise could be the best medicine for people in early stages of Parkinson's disease, researchers say. A new study reveals people with early stage Parkinson's who embarked on high intensity exercise three times a week showed a decrease in worsening motor symptoms.
