An evolution in medicine

you know the membrane that covers our brain is very jealous it doesn't allow any substances come into our brain ,scientists call it blood brain barrier (BBB) maybe its look good but its not always good ,imagine a situation that somebody has brain cancer and we need to deliver necessary drug to his brain by blood flow but BBB doesn't allow that always.

by the way now scientists in sunny brooks hospital find out a new ways to enter that barrier,in this method they used ultra sound waves to makes this barrier disable to deliver necessary drugs to the brain.
its a good news for all of the patients around the world people who have Parkinson's disease or Alzheimer's if this method is useful we can deliver proper drugs to this patients .

its just a new method and like all of the new things we need time to see how it works ,but i wish it really work for people they need that.
