Some of Alzheimers syndromes are investigated and it is demonstrated that principal reason of them is brain shrinking. In this situation size of holes in brain is smaller than natural state. Natural frequency of holes is calculated for healthy and Alzheimer brains and it is demonstrated that an applied ultrasound wave with this frequency can resonate oscillation of holes diameter and consequently can restore health of brain. Because novelty of this method, it is applied to healthy brain of sheep and this theoretical method is approved.
