Motion (physics) In physics, motion is a change in position of an object over time. Motion is described in terms of displacement, distance, velocity, acceleration, time and speed. Motion of a body is observed by attaching a frame of reference to an observer and measuring the change in position of the body relative to that frame.
ADHD, medication rates in U.S. continue to rise. Attention deficit hyperactivity disorder (ADHD) rates in the United States continue to rise, with 11 percent of children ages 4-17 having received a diagnosis in 2011, according to a study released Friday.
For example, one mother mentioned in a New York Times story last year had all of her children on ADHD treatment drugs, as well as a nightly sleep medication to counteract the effects. Sales of prescription drugs for ADHD treatment have more than doubled, going from $4 billion in 2007 to $9 billion in 2012, according to IMS Health, a health care information and technology company. The costs of the drugs can range from around $15 a month for generics to $500 a month for brand-name drugs. The popular Adderall drug averages about $280 a month, according to Consumer Reports. Thirty-five percent of parents in a Consumer Reports survey said that the costs of treating ADHD were completely covered by their childâs health plan. Taxpayers take on the costs of those covered by Medicaid. Fourteen percent of school-age children covered by Medicaid are diagnosed with ADHD, one-third higher than the rest of the population. Georgia alone spends about $28 million to $33 million on ADHD Medicaid care.
