Engineer in fatal Bronx train derailment had sleep apnea

The commuter train engineer at the center of last year's deadly derailment in the Bronx was found to have obstructive sleep apnea that went undiagnosed before the Dec. 1 derailment, a sleep medicine doctor said in the National Transportation Safety Board's investigation docket. Rockefeller told investigators that he felt fine that day, but experienced something like highway hypnosis as he stared straight ahead at the tracks. "I came up with that hypnotized feeling, dazed, that's what I was in," he said. "The only thing that shook me out of it was the feeling of the train. Something wasn't right with it.
" He activated the emergency brake, but it was too late. The train derailed as it headed around a sharp curve at 82 miles per hour, nearly three times the speed limit.

A report on Rockefeller's medical history revealed he had never been tested for a sleeping disorder by any of his doctors prior to the accident. He had a history of snoring but "not of choking or gasping" awake. His sleep was disrupted as much as 65 times per hour, the report stated.
Sleep apnea occurs when a person involuntarily stops breathing while asleep. Rockefeller's lawyer said that
"...He had absolutely no idea of this condition prior to the diagnosis. It was exacerbated by the change in shifts two weeks earlier."

 Excessive daytime drowsiness is a tendency to sleep at inappropriate times regardless of activity or circumstance. It can manifest itself in mild or severe forms.
Excessive daytime sleepiness is a common problem in today's society. It is so common that in some circles people almost consider it a normal aspect of a productive society. The fact is that daytime sleepiness and fatigue are leading causes of accidents, both on the job and on the road. The cost to society is estimated in billions of dollars per year. There are several common causes for increased daytime sleepiness. The simplest cause of daytime sleepiness that can be corrected results from insufficient sleep.

A common medical problem that can cause increased daytime sleepiness results from having a breathing problem during sleep. Snoring for example, is a form of obstructed breathing. Obstructive breathing can make it difficult to breathe properly during sleep and can even cause a complete blockage in the airway during which breathing stops. Breathing is re-established with a brief disruption of sleep and possibly a brief gasp or choking sound.

Another common medical problem causing frequent disruptions of sleep is called Periodic Limb Movements of Sleep. This occurs when a person has multiple brief leg movements every 20 to 60 seconds for long periods during the night. These leg movements can fragment sleep, resulting in increased daytime sleepiness. Frequently people with this problem also have what is called Restless Legs Syndrome (RLS). RLS occurs when a person is sitting still or lying in bed, which makes it difficult to keep their legs still. This frequently can keep people awake, causing insomnia. People with this problem feel that moving their legs relieves this restless sensation.

These problems are all treatable. Unfortunately, many physicians are not yet familiar with treating these conditions. Ask your doctor about treatment and feel free to have your doctor contact us for questions on diagnosis and treatment for these conditions.
