Attention Deficit Hyperactivity Disorder.

And so patients with depression have hyperactivity.

Attention deficit hyperactivity disorder predominantly inattentive (ADHD PI), formerly attention deficit disorder (ADD), is one of the two types of attention deficit hyperactivity disorder (ADHD).

A diagnosis frequently in the news is attention deficit hyperactivity disorder.

In ADHD, it's often assumed that the hyperactivity causes the learning disability.

Children in particular were affected by sleep disorders, hyperactivity, lack of concentration or agressivity.

But it could equally be the case that it's the learning disabilities that cause the hyperactivity.

And if you are a boy, you're four times as likely to be diagnosed with ADHD Attention Deficit Hyperactivity Disorder.

So that means that these flies have two abnormalities, or phenotypes, as we geneticists call them, that one finds in ADHD hyperactivity and learning disability.

And a final possibility is that there's no relationship at all between learning disabilities and hyperactivity, but that they are caused by a common underlying mechanism in ADHD.

Amphetamine ( contracted from ) is a potent central nervous system (CNS) stimulant of the phenethylamine class that is used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy.

But in each fly, we put it back only into certain neurons and not in others, and then we test each of these flies for their ability to learn and for hyperactivity.

Yet beyond the tantrums and the frustration and the never ending hyperactivity was something really unique a pure and innocent nature, a boy who saw the world without prejudice, a human who had never lied.

Given this harsh reality, it is not surprising that the second previously unthinkable outcome concerns inadequate policy responses namely, the large and persistent imbalance between the hyperactivity of central banks and the frustrating passivity of other policymakers.

And what this quantification showed us is that, upon experiencing a train of these air puffs, the flies appear to enter a kind of state of hyperactivity which is persistent, long lasting, and also appears to be graded.

That is, we exploit the fact that the healthy partner, playing somebody with major depression, or playing somebody with autism spectrum disorder, or playing somebody with attention deficit hyperactivity disorder, we use that as a kind of biosensor, and then we use computer programs to model that person, and it gives us a kind of assay of this.
