The article on sleepiness in neurology training in this issue ofNeurology ® adds to what is known about lack of sleep in medical trainees.1 Lack of sleep has mostly been studied in areas of medical training other than neurol-ogy. The study by Reimann and colleagues tries to fill this gap. They looked at a group of neurology doctors-in-training, called residents. They wanted to see whether the residents showed signs of sleepiness and whether sleepiness made their thinking slower and less accurate. The study found that neurology residents were sleepy but not slow in their thinking after working for a complete day and night (on call) or after working one of a series of night shifts. Sleepiness has long been a part of teaching people to become doctors, but now people inside and outside medicine are beginning to worry about the effects that sleepiness may have on patient and trainee safety. Sleep-iness may make residents more likely to make medical mistakes.2 Sleepiness may alsomake residents poor driv-ers when they leave work to go home.3 One study found that sleepy residents were about as sharp in their think-ing as people with blood alcohol levels of 0.04–0.05%.
