Attention deficit (不足) hyperactivity (活动过度) disorder is known by the letters A. D. H. D. with A. D. H. D. might have trouble paying attention. They might not seem to listen and might forget things. They might not be able to stay seated or play quietly. They might talk too much and act and speak without thinking about the results of their behavior. These are among the signs named on the web site of America's Centers for Disease Control and Prevention.
Doctors usually identify the disorder in children. But experts say the behaviors often last into adulthood. Researchers have been looking for the cause or causes of attention deficit hyperactivity disorder. Now, a brain-imaging study offers more evidence that could lead to new ways to treat it. Researchers say they observed shortages in the brain's reward system in patients with A. D. H. D. The study found that levels of some proteins were lower than normal. Nora Volkow, director of the National Institute on Drug Abuse, says the lack of attention and self-control that mark A. D. H. D. could be caused by problem in the flow of dopamine (多巴胺) . She says people might have difficulty completing an activity if they cannot expect some kind of reward in return. Researchers studied the pathways on which dopamine travels in 53 adults with A. D. H. D. Doctor Volkow says the researchers then compared the pathways to those of 44 adults without the disorder. "There was a lower concentration of dopamine markers in the brain of individuals with A. D. H. D., specifically in the areas of the brain that are involved with reward and motivation. And the dopamine levels were directly linked to the severity, of the patient's inattention" she says.
The study used brain images taken at Brookhaven National Laboratory in New York State. Gene -Jack Wing is chairman of the Brookhaven medical department. He says the finding might also help explain why people with A. D. H. D. are mere likely to abuse drugs or overeat. He says they might be attempting to increase their dopamine levels to make up for the deficits in their reward system.

New research says 35 percent of child deaths worldwide are caused by hunger. The research comes from poor to middle-income countries in Africa, Asia and Latin America.
Robert Black from the Bloomberg School of Public Health at Johns Hopkins University in Maryland is the lead writer of the research. He says more than 3.5 million mothers and children under five die in poor countries each year because of hunger.
He says about two million children die from underdevelopment, either before or after birth. Millions of others who survive face a lifetime of disabilities or early death and the effects are not just physical. Poor mental development also results from hunger as children grow. Then the
cycle of poverty and hunger often continues for their children.
Doctor Black says hungry children can have conditions like high blood pressure and heart disease as a result of hunger. He says the studies show that food programs need to place the greatest importance on the first two years of life. Hungry children can suffer their whole life damage from age two.
It is high time their diets were improved. Diets should include foods rich in vitamin A and other vitamins and minerals. The researchers say early help such as this could reduce child deaths by 25%.
This research has also faced some criticism. A medical aid group says the researchers underestimate(低估) the number of child deaths due to hunger. The researchers say there are findings that support this treatment but more studies are needed to compare it to hospital care.
