Attention deficit（不足）hyperactivity（活动过度）disorder is known by the letters A．D．H D．Children 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.B.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 and 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 Wang is chairman of the Brookdhaven medical department. He says the finding might also help explain why people with A.D.H.D.
are more 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.

A caring mother is the single most important factor in preventing teenagers from abusing（滥用）drugs and alcohol，researchers said on Friday．An international study showed that teenagers living with both parents are less likely to suffer from alcohol and drug problems，and a strong maternal bond is the most effective way to fight against them．
“These findings suggest that living with both parents may prevent drug use．”said Dr．McArdle，of Newcastle University in northern England, who led the study．“They also suggest that attachment（感情眷念），particularly to mothers，is a more effective factor and that this is truly across cultures and substances．”The report, which is published in the journal Addiction, involved nearly 4,000 teenagers in England，Ireland，Italy，Germany and the Netherlands．They were questioned about their use of several kinds of drugs and alcohol．The teenagers also filled in questionnaires about their relationship with their parents and grandparents, how well they were supervised（监护）after school and whether they were allowed to meet friends at home．
“Both the quality of family relationships and the structure of families have significant influences on youth drug use,” McArdle said in a statement．But he added that a strong maternal bond offered the greatest protection against developing drug habits．The rate of drug abuse among teenagers living with both parents and who had a good relationship with their mother was 16．6 percent．If either factor was missing, the drug abuse rate rose to 32 percent．More than 42 percent of teenagers living in one parent families who did not have a strong bond with their mother used drugs．
Drug prevention campaigns in British schools and on television warn teenagers about the danger of drugs and alcohol but McArdle said no one is dealing with the problem of their parents’ responsibility

“I didn’t think drugs were a big deal.”
