Health care professionals, educators and patient advocates debate endlessly over attention deficit disorder.
Some argue about the cause of the condition, which is associated with inattentiveness and, often, hyperactivity. Many disagree on treatment and parenting techniques. A dwindling group disputes whether it actually exists..
Some practitioners and researchers say drugs are by far the most effective treatment. Others argue that long-term drug use addresses symptoms only and does not provide important tools to help people manage their inattentiveness. They say it’s more helpful to focus on behavioral interventions, nutrition, exercise and special accommodations at school.
The American Psychiatric Association says there is no doubt that ADHD exists – and it estimates that 5 percent of U.S. children have the condition.
The Centers for Disease Control and Prevention puts the figure higher, reporting that 11 percent of U.S. children age 4 to 17 had been diagnosed with ADHD as of 2011.
Whatever the number, many parents of kids with attention problems struggle with how best to help them. They seek guidance on whether to medicate. They want to know how to advocate for them in school and with their doctors. They look for ways to help them grow into well-adjusted, successful adults.
Science recognizes ADHD as involving brain development, although there is disagreement over what exactly happens in the brain to trigger ADHD symptoms. Barkley says there is an inherited aspect, though he also says the condition is sometimes triggered by environmental factors such as exposure to smoke and alcohol before birth. ADHD impairs self-regulation of behavior and emotions. And it impairs regulation of thoughts involving planning, organizing and problem-solving, he said.
Research shows that the maturation of brain regions associated with these functions is delayed by about three years in people with ADHD. Studies also suggest that these regions are smaller than normal and that they are less active. Also, imaging tests show dysfunctions in the networks of nerve cell fibers that allow brain regions to communicate with one another.
“Some of these networks affect working memory, which allows us to retain information. This explains the forgetfulness and difficulty completing tasks,” Barkley says. “A network tied to timing of our actions explains why these people are chronically late. A network tied to impulse control explains why they have five times more speeding tickets and why their relationships often head south. A network affecting ability to sustain attention is why they, for instance, have three times more car accidents.”
Whether children should be treated with medication sets off debate. “Some families say medications changed their child’s life for the better; others tell you horror stories,” said Ruth Hughes, former chief executive of Children and Adults with Attention-Deficit/Hyperactivity Disorder.
Advocacy groups such as CHADD suggest a mixed approach that may include medication but also entails the application of parenting skills, behavioral interventions and school support.
Studies have produced contradictory results on the effectiveness and safety of medications for ADHD. A 2014 article in the Journal of Health Economics, based on a 14-year study involving 8,643 children with ADHD, concluded that “expanding medication … had little positive benefit and may have had harmful effects, given the average way these drugs are used in the community.” Yet a 2014 meta-analysis of 25 studies concluded,
“Short-term (drug) treatment is safe and superior to placebo for ADHD symptoms and secondary outcomes.”
Hughes says parents should decide with their children’s doctors whether to use medication; for additional advice, she recommends “ADHD: Parents Medication Guide,” a booklet prepared by the American Academy of Child and Adolescent Psychiatry and American Psychiatric Association.
“It’s based on science, but it’s not all about ‘Yes, medicate your kid,’ ” Hughes said. “It takes a thoughtful approach.”
Hope Scott, a developmental pediatrician in Reston, Virginia, prescribes medication to most of her ADHD patients. But drugs are only one part of the plan.
“Medications improve distractibility,” Scott said. “But they do not touch development of time management or organizational skills. They help you focus on cleaning your room, but you still need to learn how to do it.”
To teach such skills, she suggests ongoing behavior management measures such as reward tokens redeemable for such things as sleepovers with friends. Scott also recommends educational support, including classroom accommodations, such as more time to take tests or working on homework assignments during school hours for students who can’t focus after a full day of school.
Nitya Ramachandran, an Olney, Maryland, integrative pediatrician focusing on nutrition and other complementary and alternative medical protocols, has parents keep a diary noting what their children eat and when their symptoms worsen. Some studies, including a recent one in European Child Adolescent Psychiatry, suggest that food additives provoke ADHD behaviors, though the National Institutes of Health reports only a small percentage of children improve by restricting these additives.
“From the diaries and what parents tell me, many kids find it harder to focus, are tired or hyper when they eat processed foods and, in some cases, food additives like artificial dyes,” Ramachandran said.
Sometimes symptoms subside when these ingredients are eliminated. Ramachandran prescribes fish oil and probiotics to promote nutrient absorption. She checks thyroid hormones, vitamin D and iron levels – studies suggest deficiencies in these areas may be associated with ADHD – and emphasizes the importance of sleep.
Nearly 70 percent of her patients take low-dose medication; about half are weaned off them once they can focus on academics and their stress levels subside – usually within several months.
“They do well,” she said. “But they follow this integrative approach looking at overall health.”
Hard to diagnose
ADHD is hard to diagnose because there are usually coexisting conditions with related symptoms, such as obsessive-compulsive disorder or learning disabilities including dyslexia, said Barry Ekdom, a Fairfax, Virginia, neuropsychologist.
Like many other neuropsychologists, he assesses for ADHD by taking the patient’s history and testing several functions such as memory retrieval, which in some cases may be an indicator of ADHD and or other cognitive problems.
“People with ADHD get it when they study, but they blow the test – that is memory retrieval. The knowledge is learned and remembered. But they can’t retrieve it when questioned,” Ekdom said.
He suggests having ADHD children practice accessing information, such as repeatedly answering review questions before a test rather than simply reading material to be covered.
Auditory and visual cues – such as to-do lists and recorded messages – can help, some experts say.
