利祂靈： ADHD藥物也許影響開發的腦子

利祂靈-被給大約5百萬個年輕美國人診斷與ADHD (關注性赤字，活動過度的混亂) -可以影響開發的腦子。

利祂靈(哌醋甲酯)是興奮劑相似與安非他明和可卡因和它似乎有一個似是而非的作用在ADHD孩子，并且鎮定他們。

But it may do so at a price, new research suggests.  The new study, which monitored the effect of the drug on the brains of rats, found that it altered areas of the brain related to executive functioning, addiction and appetite, social relationships and stress.

The rats recovered the longer they were off the drug, researchers noticed.

Although there’s often no direct correlation between the effects on animals and humans, the rats did respond in a similar way when they were first given Ritalin.  They lost weight, which often happens in children who first take the drug.

The fact that the rats soon regained their healthy mental capacities suggests the drug should be taken over a short period of time rather than for years as currently happens, the researchers say.
