Ultrasound could help fight against Alzheimer's disease
According to scientists, an experimental and non-invasive technique using ultrasound helps remove the brain plaques in mice, which could lead to Alzheimer’s disease.
According to the study in the journal Science Translational Medicine, using sound waves to penetrate tissue removed most of amyloid plaque in 75% of the animals studied, without causing any harm to brain tissue.
According to James Hendrix, director of global science initiatives for the Alzheimer's Association, "We know that amyloid interferes with the function of neurons and causes brain cells to die, but not everyone with amyloid in their brain will go on to develop Alzheimer's or another dementia".
The mice, which were genetically modified to develop the disease, were treated over the course of several weeks. It was found in the study that most of the animals, which were treated, showed better results in mazes, memory tests and some other tasks compared to untreated mice.
Researchers at the University of Queensland in Brisbane, Australia are now looking forward to use the method in sheep. It is yet unclear whether the technique would work effectively in human beings.
Ultrasound devices, which can penetrate the human brain, are being used for other conditions as well.
According to Alzheimer's Disease International, a non-profit campaign group, Alzheimer’s is the most common form of Dementia and around 50 million people worldwide suffer from the disease and this number could reach around 135 million by 2050.
The study is first to suggest that ultrasound is enough to benefit the memory loss in Alzheimer's disease.
Juergen Goetz of the University of Queensland in Brisbane, one of study authors, told Reuters that their research was quite informative and they didn’t think that it would show such a result.
