The Mona Lisa is arguably the world's most famous painting -- and yet, like many of Leonardo da Vinci's works, it's also considered unfinished. Half a millennium after his death, new research has identified a potential explanation behind the Renaissance artist's series of uncompleted projects: attention deficit hyperactivity disorder, or ADHD.

The authors of a new study led by the University of Sydney suggest a lack of clarity on appropriate maximum dose limits for stimulant medication for Attention Deficit Hyperactivity Disorder (ADHD) could be confusing for doctors, with some patients potentially not receiving sufficient dosages...The meta-analysis, published in JAMA Pediatrics today, examined 49 international studies administering a common stimulant by titration (testing a range of doses to find the best dose for the individual) to over 6800 children and adolescents with ADHD.

The review included 2 trials in patients with ADHD (n=278) and 2 trials in patients with autism (n=124). According to the analysis, overall sleep quality was improved with minimal risk of adverse events in these populations. The study authors recommended that melatonin only be used following optimization of stimulant dosing in patients with ADHD.

The takeaway: that an increasing number of students are getting 504 accommodations and extended time on the ACT and SAT, and that a disproportionate number of these students are from wealthy school districts...However, the students I work with who do receive accommodations (not as many as you might think) have very obvious and real problems that impact their lives far beyond standardized tests.

If your child is always engaging in roughhousing and has a very short attention span at home and at school, you may be worried that he or she has Attention-Deficit/Hyperactivity Disorder, better known as ADHD. Depending on your child’s age though, these may just be normal behaviors for that developmental stage. How to tell the difference?

These days, we know a lot more about ADHD, its potential causes, its effects on other disorders, and effective ways to treat it. However, you may not have dipped beneath the surface of ADHD to learn more about this fascinating condition, and there's a lot to know.

Some babies are easy-going and others are just hard. But could your little one’s behavior as an infant signal problems down the road? Scientists say maybe. They examined 342 kids at ages five months, 20 months, and at four and a half years old – and again at ages six, eight, and 28 years old.

If you have a child with ADHD, it might seem initially difficult to create coping strategies. Yet, with just a bit of creativity and determination, you can effectively help your child cope with ADHD. Here are ten ways to help you do that:

Stephen V. Faraone, PhD, Distinguished Professor at Upstate and a leading researcher on attention deficit hyperactivity disorder (ADHD), has been elected president of the World Federation of ADHD. Faraone will serve a four-year term, which began last month. He previously had served for eight years as vice president...He is also a member of the Children and Adults with Attention Deficit/Hyperactivity Disorder Hall of Fame...
