A new Alzheimer’s treatment called focused therapeutic ultrasound beams sound waves into brain tissue and stimulates the brain’s waste removal system, safely enabling a clearance of the plaques, clumps and tangles that block memories. This non-invasive technology uses sound waves to safely open the blood-brain barrier where your ‘janitorial’ microglial cells can sweep out the garbage for a few hours, including beta-amyloid clumps (sticky proteins) and neurofibrillary tangles (that clog neurons), the two most common lesions in the brain that build up over time, blocking memories while leading to strokes and dementia. A team at the Queensland Brain Institute in Australia was successful in treating 75 mice with focused therapeutic ultrasound, with astonishing 75 percent success rate at restoring memory.
