Researchers have successfully reversed symptoms of Alzheimer’s disease in mice by using MRI-guided ultrasound. Studies working with Alzheimer’s mouse models have shown improved cognition and spatial learning, with no adverse effects on behavior.
The theory is that this technique works because as the ultrasound beams temporarily open the blood-brain barrier, drugs are able to be delivered to the brain more efficiently. The contrast agent used during the ultrasound helps the process increase the number of new neurons in the brain.
Working with mice is the first step. Researchers have found that physical signs of Alzheimer’s have been improved through this procedure, but cognition and memory tests are needed as well. Hopefully, the promising results in mice will translate into humans. Read more about this research here.
