Ultrasound Waves Applied to Brain Could Be a Treatment for Dementia—Free of Side Effects

Source: Good News Network

Japanese scientists have found that applying ultrasound waves to the brain can improve cognitive dysfunction – and possibly combat dementia.

The research found that applying low-intensity pulsed ultrasound (LIPUS) to the brains of mice improved blood vessel formation and nerve cell regeneration without having obvious side effects.

The research, which was conducted by scientists at Tohoku University in Japan and led by cardiologist Hiroaki Shimokawa, shows promising results for human treatment.

“The LIPUS therapy is a non-invasive physiotherapy that could apply to high-risk elderly patients without the need for surgery or anesthesia, and could be used repeatedly,” says Shimokawa.

Despite dementia affecting about 50 million people worldwide, there are currently no curative treatments available for vascular dementia or Alzheimer’s disease, the most common causes of dementia. Also, the cells lining the brain’s blood vessels are tightly packed, forming a blood-brain barrier that prevents large molecules from crossing into the brain tissue. This limits the types of drugs and cell therapies that could be made available to treat dementia.

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…
