By the time kids diagnosed with attention deficit hyperactivity disorder meet with clinical psychologist Mary O'Connor, they have often been taking multiple medications or unusually high doses of stimulants like Ritalin. "They may have had a trial of stimulants that worked initially," she says, but when the effect waned, their physicians prescribed higher doses, sometimes to the point of toxicity.
O'Connor researches fetal alcohol spectrum disorders at the University of California, Los Angeles, where she has provided both diagnosis and treatment to children exposed to alcohol in the womb. At one end of the spectrum sits fetal alcohol syndrome, characterized by facial abnormalities, growth problems, and intellectual disabilities. The other end of the spectrum is characterized by subtler symptoms, including poor judgement and impulsivity — in other words, what looks to many like ADHD.
