The blood-brain barrier has been broken for the first time in history. Doctor Todd Mainprize, of the Sunnybrook Health Sciences Centre in Toronto, and in concert with other neuroscientists, has successfully broken the blood-brain barrier, opening the way for revolutionary new treatments for brain cancer, Alzheimer’s, depression, stroke, Parkinson’s, and more.

The procedure, which took place earlier in the week according to CTV News, was used to successfully treat Bonny Hall’s brain tumor by non-invasively delivering medication deep into the brain using microbubbles and focused ultrasound to force cancer medication through the blood-brain barrier. Dr. Mainprize discussed the revolutionary treatment with CTV.

“Frankly speaking, our ability to treat this type of tumour, glioma, is not so good. […] Between 1940 and 2005, there has been very little progress in improving the outcome of these patients.”

“It went exactly as hoped.”

The treatment involves first dosing the patient with medication. Afterward, harmless microbubbles are injected into the bloodstream, and a high-intensity ultrasound beam is directed at the tumor, causing the microbubbles to vibrate. This gently tears the proteins around the capillary walls, allowing the medication to painlessly and harmlessly enter the brain tissue, something that has been impossible to achieve up to this point.
