Focusing on A.D.D
When 8-year-old Clayton Petersen began taking yoga, he had a hard time staying focused. He would assume a posture and then get distracted. His teacher, Kathleen Randolph, had to recapture his attention about once every minute, guiding him back to the center of the room and then into the next asana. She recalls these first lessons, staged within the confines of her small basement studio, were "like being inside a pinball machine." Clayton bounced from wall to wall, scattering his considerable energies throughout the studio in a way any parent of a hyperactive child with Attention Deficit Disorder (ADD) would immediately recognize.
The clinical label ADD describes one of the most commonly diagnosed behavioral impairments of childhood, affecting an estimated 3 to 9 percent of the school-age population and 2 percent of adults. While most outgrow their hyperactivity in adolescence, about two-thirds carry other symptoms like distractibility into adulthood.
ADD's core symptoms include inattention, difficulty following directions, poor control over impulses, excessive motor activity in many but not all cases, and difficulty conforming to social norms. But low intelligence is not among these, despite the fact that ADD can hamper learning. On the contrary, a great majority of those diagnosed enjoy above-average intelligence. Bonnie Cramond, Ph.D., associate professor of education at the University of Georgia, authored a provocative paper comparing the symptoms of ADD with creativity. She found that children diagnosed with ADD share traits with such innovators as Robert Frost, Frank Lloyd Wright, and Leonardo DaVinci.
Since the 1940s, psychiatrists have used various labels to describe children who seem inordinately hyperactive, inattentive, and impulsive. These labels have included "minimal brain dysfunction," "hyperkinetic reaction of childhood," and, since the 1970s, "Attention Deficit Hyperactivity Disorder" (ADHD). But it turns out that certain children are inattentive and easily distracted without being hyperactive. These quiet, spaced-out kids don't disrupt class and often go unnoticed.Today the simpler label Attention Deficit Disorder has gained favor to acknowledge attention deficits that come with or without hyperactivity.
For decades, doctors blamed ADD on bad parenting, character weakness, refined sugar, and a host of other causes. Recent research, however, using sophisticated brain-scanning technology suggests a subtle neurological impairment. Studies report that several brain regions in ADD appear underdeveloped, most notably the right prefrontal cortex—an area of the brain associated with inhibition. It turns out that inhibition acts as a precursor to concentration.
One's ability to concentrate emerges from restraining mental distractions in a process neurologists call "neural inhibition"—a description that squares with Patanjali's definition of concentration as "quieting the mind of its compulsions." Here's how it works: As you read this sentence, your brain intensifies the neural circuits related to language by suppressing competing stimuli like ambient sounds, peripheral vision, and extraneous thoughts. The contrast created between the circuits highlighted and those inhibited allows you to focus your concentration. In the ADD brain, the inhibiting portion of the system malfunctions. ADD brains get flooded with competing stimuli and lack the means to sort them out; each internal voice shouts as loudly as the others.
