Brain Inflammation and link to Dementia.
Long term inflammation could be the cause of dementia in concussion football related injuries.
Manual lymphatic drainage reduces inflammation built up in areas of the body, could MLD as a rehab therapy for concussion injuries be a natural non invasive way to limit the ongoing buildup of inflammation. Especially now with findings of lymph vessels in the brain.
MLD is not a well known therapy for head trauma, but it can make a big difference in the reduction of swelling.
