It's such a rare disease, it would be hard for a company to justify spending hundreds of millions of dollars to generate a drug.
This is the 21st-century biology that you've been waiting for, and we have the chance to take that and turn it into something which will, in fact, knock out

We know, because in the mid-19th century, wonderful Victorian engineers installed systems of sewers and wastewater treatment and the flush toilet, and

It's a little different than the way we think about brain disorders like Huntington's or Parkinson's or Alzheimer's
disease
where you have a bombed-out part of your cortex.
And it's important, if you try to model this, you can think about normal development as a loss of cortical mass, loss of cortical gray matter, and what's happening in schizophrenia is that you overshoot that mark, and at some point, when you overshoot, you cross a threshold, and it's that threshold where we say, this is a person who has this disease, because they have the behavioral symptoms of hallucinations and delusions.
If we waited until the heart attack, we would be sacrificing 1.1 million lives every year in this country to heart
disease.
But they thought that, if you had a neurologic or psychiatric disease, it must be because you are possessed by an evil spirit.
There were some sites where one percent of all the skulls have these holes, and so you can see that neurologic and psychiatric
disease
is quite common, and it was also quite common about 7,000 years ago.
So when these neurons are in the motor circuit, you get dysfunction in the movement system, and you get things like Parkinson's
disease.
When the malfunction is in a circuit that regulates your mood, you get things like depression, and when it is in a circuit that controls your memory and cognitive function, then you get things like Alzheimer's
disease.
Now the first example I'm going to show you is a patient with Parkinson's disease, and this lady has Parkinson's disease, and she has these electrodes in her brain, and I'm going to show you what she's like when the electrodes are turned off and she has her Parkinson's symptoms, and then we're going to turn it on.
This boy is nine years old, perfectly normal until the age six, and then he started twisting his body, first the right foot, then the left foot, then the right arm, then the left arm, then the trunk, and then by the time he arrived, within the course of one or two years of the
disease
onset, he could no longer walk, he could no longer stand.
We did not know what operation to do, where to go in the brain, but on the basis of our results in Parkinson's disease, we reasoned, why don't we try to suppress the same area in the brain that we suppressed in Parkinson's disease, and let's see what happens?
I've shown you that we can use deep brain stimulation to treat the motor system in cases of Parkinson's

and dystonia.
We're going to do this in people that have cognitive deficits, and we've chosen to treat patients with Alzheimer's
disease
who have cognitive and memory deficits.
As you know, this is the main symptom of early onset Alzheimer's
disease.
So we've placed electrodes within this circuit in an area of the brain called the fornix, which is the highway in and out of this memory circuit, with the idea to see if we can turn on this memory circuit, and whether that can, in turn, help these patients with Alzheimer's
disease.
Now it turns out that in Alzheimer's disease, there's a huge deficit in glucose utilization in the brain.
Twenty percent of all the glucose in your body is used by the brain, and as you go from being normal to having mild cognitive impairment, which is a precursor for Alzheimer's, all the way to Alzheimer's disease, then there are areas of the brain that stop using glucose.
So the lights are out in parts of the brain in patients with Alzheimer's disease, and the question is, are the lights out forever, or can we turn the lights back on?
