Magnetic stimulation using a laptop-style device for 20 minutes per day improved the ability of rodents with concussion to walk in a straight line, navigate a maze, run on a wheel, and perform cognitive tests, according to research published in the Journal of Neurotrauma. Within four days of treatment, rodents with repeated concussion had their ability to perform a variety of cognition and motor tests restored to almost normal levels. Their bodyclocks, governing sleep patterns, which can be thrown out of sync by concussion, were also restored to their normal function.
Researchers also found that certain proteins, which are important to protect the brain from various neurological conditions, were restored to their normal level by the low-frequency magnetic stimulation. The proteins protect neurons and halt the progression of post-concussion inflammation and neurodegeneration.
