In 2011, when the American Academy of Pediatrics began including preschoolers in its guidelines for diagnosing and treating attention deficit hyperactivity disorder, some media reports blasted the idea. Were we planning to medicate toddlers? Would A.D.H.D. diagnoses surge once pediatricians started looking for it in preschoolers?

Genetics play a strong part in the development of attention-deficit/hyperactivity disorder (ADHD), but the path from a gene to risk for the disorder has remained a black box to researchers.. A new study suggests how the risk gene ADGRL3 (LPHN3) might work. ADGRL3 encodes the protein latrophilin 3, which regulates communication between brain cells. According to the study, a common variation of the gene associated with ADHD disrupts its ability to regulate gene transcription - the formation of mRNA from DNA that leads to expression of the gene.

Hyperactivity seems to be the result of not being able to focus one's attention rather than the other way around. This was proposed in an article in PLOS ONE, written by researchers at Radboud university medical center and Radboud University. It seems to suggest that more attention should be given to the AD than to the HD component.

The College Board announced on Thursday that it would make it easier for students with disabilities to request test accommodations, and that it would provide, for the first time, testing supports to some English-language learners who take the SAT. The College Board and its competitor, ACT Inc., have increasingly faced criticism—and questions from the U.S. Department of Justice—for testing practices that put students with disabilities at a disadvantage compared to students without disabilities.

Hi. I am Dr Hansa Bhargava, a practicing pediatrician and medical editor with Medscape. Have you ever had a parent of a child with attention-deficit/hyperactivity disorder (ADHD) ask about ways to treat it without medication? I seem to be getting this question more and more.

I'm talking about children with ADD, now more commonly referred to as ADHD -- Attention Deficit Hyperactivity Disorder. Those born with this disorder require a lot of patience and understanding, but in the end, did you know that they can also turn out to be among the most successful individuals around because of (not in spite of) their quirks?

People with ADHD don’t always know how to do things in moderation. Maybe that explains why so many ADHDers aren’t content with just one mental health condition and have other “comorbid” conditions such as depression or anxiety on top of ADHD."
