Ultrasound returned memory in mice with Alzheimer's disease

Australian researchers regained memory mice , which was struck by the brain болезнью Alzheimer . After exposure to ultrasound mice showed much better results on tests of memory and orientation in space.

Although it is not precisely known cause of the disease, one of the hypotheses states that disease is caused by the appearance in the brain of excessive amounts of amyloid beta cells. This accumulation of proteins normally broken down in the brain, but people exposed to the disease, the brain can not cope with the splitting.

Search the treatment of the disease is complicated by the fact that the brain is separated from the blood flow гемато-энцефалическим barrier - filter that protects the brain from microorganisms and toxins that can enter the bloodstream. This filter also successfully prevents penetration into the brain mostly drugs.

Scientists decided to try to have an impact on non-invasive brain via ultrasound waves. It turned out that this procedure stimulates the микроглии - special brain cells that destroy various infections, penetrated into the brain. Mice brain which was subjected to ultrasound, the number of beta-amyloid cells decreased by 75%. Thereafter, mice showed a significant improvement in results in the various tests.

Researchers feel cautiously optimistic and soon plan to test a new method of dealing with the terrible disease in sheep, before moving on to human trials.
