Harry Potter and the Reader's Poundage Headache
Howard J. Bennett, a pediatrician in Northwest Washington, was alerted to the peril when three patients, ages 8 to 10, complained in June that they had been suffering from headaches for two or three days.
"In each case, the headache was dull and the pain fluctuated throughout the day," Bennett wrote in a letter published in today's issue of the New England Journal of Medicine.
One child also complained of neck and wrist pain, but none had a fever or any other symptoms that would suggest he was suffering from something serious, such as an infection or neurological problem, he said.
"On further questioning, it was determined that each child had spent many hours reading J.K. Rowling's latest book in the Harry Potter series," Bennett wrote in the letter, which journal editors titled "Hogwarts Headaches -- Misery for Muggles."
In Rowling's series, Hogwarts is the name of the school for witches and wizards that the bespectacled Harry Potter attends, and Muggles is the name applied to humans.
"The presumed diagnosis for each child was a tension headache brought on by the effort required to plow through an 870-page book. The obvious cure for this malady -- that is, taking a break from reading -- was rejected by two of the patients, who preferred acetaminophen instead," Bennett wrote, referring to the painkiller sold as Tylenol and other brand names.
