According to a new study on mice, people who suffer from Alzheimer's disease could benefit from sonic waves, once used in World War II by submarines. Sonic waves could help patients improve their ability to remember and also navigate.

Although there is a long way for the research to reach humans, it opens the door to know more about Alzheimer's therapy. According to authors of the study, the technique used in the study could help treat other diseases, in which abnormal protein accumulates in the brain.

The forebrain of mice, raised to develop Alzheimer's disease, was stimulated with scanning ultrasound for more than six to seven weeks. It was found that it triggered specialized immune cells in the brain to collect and discard excess amyloid.

According to Professor Jurgen Gotz of Australia's Ageing Dementia Research body, the new treatment method could transform Alzheimer's treatment by restoration of memory.

The new research has been published in the journal Science Translational Medicine. For the first time, a study has suggested that a safe, sound, noninvasive and well-understood diagnostic technology could improve the brain's slower trash-removal system and stop or reverse the disease's course.

According to Gotz, "We're extremely excited by this innovation of treating Alzheimer's without using drug therapeutics. The ultrasound waves oscillate tremendously quickly, activating microglial cells that digest and remove the amyloid plaques that destroy brain synapses". It has been found by Australian researchers that non-brain invasive ultrasound technology can help in treatment of Alzheimer's disease and also restore memory.

On Thursday, the findings were announced by the University of Queensland (UQLD). It was also announced that the new treatment could require no drugs.
