One of the best-known sleep disorders is narcolepsy, a serious medical condition that causes sufferers to be suddenly overwhelmed by feelings of fatigue. But narcolepsy symptoms also include abnormal episodes of "dreaming sleep," which are similar to hallucinations, and attacks of "cataplexy," in which a person loses control of certain muscles for a few seconds at a time.
One in every 2,000 Americans has narcolepsy. Here are a two you may have heard of.
Believe it or not, Harriet Tubman was a narcoleptic. The African-American abolitionist who freed hundreds of slaves in pre-Civil War America is famous for her strength of will, but less known for her weakness for sleep. As a 12-year-old girl in Maryland, Tubman received a serious blow to the head from her slave master. She never fully recovered, and the injury was said to cause her intermittent bouts of narcolepsy from which she suffered for the rest of her life.
But if Ickes was bitter about his sleep disorder, he certainly couldn't blame it on his genes. Ickes' father, Harold LeClair Ickes, was also an advisor to a president, Franklin D. Roosevelt, and a member of his cabinet. But unlike the younger Ickes, Harold LeClair was a life-long insomniac, never known to get more than three or four hours at a time.
