The answer to helping kids with “lazy eye” before it’s too late could be a hand-held screening device, a new study suggests. Amblyopia can’t be treated with glasses or contact lenses after a child’s vision reaches maturity, and without treatment, it can lead to poor school performance and impairments in depth perception and fine motor…  read on >  read on >

Researchers have created a six-stage process to help families of children with attention deficit hyperactivity disorder (ADHD) deal with the disorder. “This framework is family-centered, focused on breaking down the barriers that families face from before diagnosis to preparing children with ADHD for the future,” said Dr. Andrea Spencer, director of the Reach for ADHD…  read on >  read on >

Preschoolers with attention deficit hyperactivity disorder (ADHD) rarely receive the gold-standard treatment recommended by the American Academy of Pediatrics (AAP) for their condition, a new study reports.
