“If modern psychology had existed back then, Tom would have probably been deemed a victim of ADHD (attention deficit hyperactivity disorder) and prescribed a hefty dose of the ‘miracle drug’ Ritalin. At age seven – after spending 12 weeks in a noisy one-room schoolhouse with 38 other students of all ages – Tom’s overworked and short tempered teacher finally lost his patience with the child’s persistent questioning and seemingly self-centered behavior. Noting that Tom’s forehead was unusually broad and his head was considerably larger than average, he made no secret of his belief that the hyperactive youngster’s brains were ‘addled’ or scrambled.” (The Biography of Thomas Edison)
Thomas Edison (born Feb. 11, 1847; died Oct. 18, 1931) is mentioned more often than any other historical figure for exhibiting classic ADHD behavior. As a poster child for ADHD, Thomas Edison would have been an excellent participant in the research study described on Oct. 31, 2012 in the article A little exercise may help kids with ADHD focus.
