Dr. Dennis Charney stepped forward to address the court here, the man who tried to kill him standing no more than 20 feet away. He stated his full name for the record and then began detailing what happened. How one morning as he picked up his iced coffee and lightly buttered bagel, he heard a shotgun boom and saw blood pouring from his shoulder and chest.

Over the past two decades, U.S. parents and teachers have reported epidemic levels of children with trouble focusing, impulsive behavior and so much energy that they are bouncing off walls. Educators, policymakers and scientists have referred to attention-deficit/hyperactivity disorder, or ADHD, as a national crisis and have spent billions of dollars looking into its cause. They've looked at genetics, brain development, exposure to lead, the push for early academics, and many other factors. But what if the answer to at least some cases of ADHD is more obvious?

Why shouldn’t people who hate the little blood suckers in the backyard, as well as those who love them in the lab, be able to express their feelings about them in a single character via text or on social media, ask Marla Shaivitz, a digital communications manager at the Johns Hopkins Bloomberg School of Public Health’s Center for Communication Programs, and Jeff Chertak, a senior program officer for malaria advocacy and communications at the Bill & Melinda Gates Foundation.

Every time Jacque Pearson tried to devise a plan to move her 81-year-old dad, who has Alzheimer’s, from his home in Boise, Idaho, to hers in Denver, she felt stuck. Then, two weeks ago, she had a breakthrough. It happened at an AARP-sponsored session in which Pearson created a “CareMap” — a hand-drawn picture showing all the people she cares for as well as the people surrounding those individuals and her own sources of support.
