That could be a secret to preventing the disease from developing in its early stages but the -- actual vaccine to potentially prevent alzheimer's.
I think this is very exciting -- is coming out of Georgetown in the was present in the Society for Neuroscience -- this year in mice again.
But what they did was they looked at the brain and when -- store so washed well I'm starting.
That was -- time is about to occur and amyloid protein builds up in the brain and when they saw that happening before Erica -- really built up.
They injected amyloid into the brain of the mice and when the brain saw the amyloid coming to develop antibodies to it.
And stop it from progressing -- in other words if you give amyloid before -- help time developed.
Before alzheimer's disease develops there's a good chance you can prevent its progression preliminary.
-- they are they doing these tests on the mice when when you think I guess of the humans.
I'd -- a couple of years we're not -- quite ready for prime target of this is going to be a few years until we get there but the biggest problem with Alzheimer is really diagnosing it diagnosis of -- -- -- us timer.
Is the biggest challenge we're starting to understand that at -- -- is what causes inflammation in his slows down.
And he's a 100% right his bio markers are simple test.
Whereby just drawing a blog you're able to see that you're heading over there or you may have more susceptibility to the forming his -- -- If it's given beforehand you can prevent it but how do we diagnose -- that's our biggest challenge and finding a vaccine.
It's even harder but certainly this is a step toward but solving this.
Problem flu have within a few years they've -- -- right direction I'll be awesome all right well this new recommendations this year.
Against using PSA test to screen healthy men for prostate cancer.
Against -- doctor's mind.
What US test scores this year came up and said that men or that are healthy over the age of fifty should not get any kids say because it doesn't help them -- mortality.
Similar recommendation to mammogram which as you know -- cause a lot of controversy last country.
-- looked at two studies one from Europe and America would not do you follow up and they said well in during this period it didn't cause.
-- help these men and so we don't recommend it which was a little bogus because.
Most studies and longer term from sooner than fourteen years show -- -- actually saves lives.
Now we know that PSA stands for prostate specific antigen.
Not prostate cancer specific antigens so things such as enlarged prostate informational prostate and prostate cancer can.
You have to make sure that you talk to a doctor.
I'm -- -- who is at risk group called it risks Stratton education.
One person may be at risk and the other one is not not every out of it appears -- means biopsy not every positive biopsies surgeries now.
This is what we are talking about in the -- logic field if that PSA found the cancer and quote from the prostate cancer was perfect in a good world.
Everyone is secure -- -- was continent and everyone had sexually active -- that he didn't say when given normal prize right -- I would say this -- helped me.
But I would say it is is we need to concentrate on improving our -- home.
And better trained surgeons.
Maybe this technology experience of oncology and help our patient not to put our head in the senate -- No -- -- that's all we had to quickly on the test it because I know the next topic is for doctor Siegel practiced writing and what about physical examination for healthy man instead of the PSA test is that enough.
It's not enough it's not being said you need to have the exam and the PS and I'm glad you brought it up because -- will we see prosecutors are in younger men in their forties and fifties it's.
-- the art of medicine.
And this 30% less deaths from prostate cancer since the PSA came into practice.
And 30000 men are still dying of prostate cancer I need this arrow in my quiver as a primary care doctor.
I do a PSA and Everyman over the age of forty once they have appears very question is what I do with the -- recheck your door follow it to look for a trend to -- the patient the doctor somebody it depends on the patient I'm glad to -- his -- board because a lot of internist.
Are always -- having -- about Houston assumes a great test.
