18 Mar Attacking Alzheimer’s with Ultrasound
For the first time, researchers have reversed some of the symptoms of Alzheimer’s disease in mice using magnetic resonance (MR) imaging-guided focused ultrasound.
MR imaging-guided focused ultrasound has been shown to temporarily open the blood-brain barrier (BBB), which allows for more effective delivery of drugs to the brain. In order to accomplish this, researchers use a microbubble contrast agent. The microbubbles vibrate when they pass through the ultrasound beam, temporarily creating an opening in the BBB for the drugs to pass through. In addition, this combination of ultrasound and microbubbles has been shown to increase the number of new neurons and the dendrite length.
