Patients with dementia can now be treated with ultrasound applied to the brain.
Ultrasound waves, applied to the entire brain, improve cognitive dysfunction in mice with conditions simulating vascular dementia and Alzheimer's disease.
Research, conducted by scientists at Tohoku University in Japan, suggested that this type of therapy could also benefit humans.
Led by cardiologist Hiroaki Shimokawa, the team discovered that low intensity pulsed ultrasound (LIPUS) whole brain mice improved blood vessel formation and regeneration of nerve cells without obvious side effects .
"LIPUS therapy is a non-invasive physiotherapy that could be applied to high-risk elderly patients without surgery or anesthesia, and dementia affects approximately 50 million people worldwide, with 10 million new cases each
Shimokawa and his team had conducted previous studies showing that LIPUS improved blood vessel formation in pigs with myocardial ischemia, a condition where there is reduced blood flow to the heart.
The researchers conclude that their study provided the first experimental evidence that whole brain LIPUS therapy dramatically improves cognitive dysfunction without serious side effects by improving specific cells related to the pathology of dementia.
The full results are published in the journal – Brain Stimulation.
