Major Bay 1 of the ER, I was still convulsing violently, while intermittently groaning and flailing my arms and legs.
It was obvious to Dr. Potter from the way I was raving and writhing around that my brain was under heavy attack. A nurse brought over a crash cart, another drew blood, and a third replaced the first, now empty, intravenous bag that the EMTs had set up at our house before loading me into the ambulance. Asthey went to work on me, I was squirming like a six-foot fish pulled out of the water. I spouted bursts of garbled, nonsensical sounds and animal-like cries. Just as troubling to Laura as the seizures was that I seemed to show an asymmetry in the motor control of my body. That could mean that not only was my brain under attack but that serious and possibly irreversible brain damage was already under way.
The sight of any patient in such a state takes getting used to, but Laura had seen it all in her many years in the ER. She had never seen one of her fellow physicians delivered into the ER in this condition, however, and looking closer at the contorted, shouting patient on the gurney, she said, almost to herself, “Eben.”
Then, more loudly, alerting the other doctors and nurses in the area: “This is Eben Alexander.”
Nearby staff who heard her gathered around my stretcher. Holley, who’d been following the ambulance, joined the crowd while Laura reeled off the obligatory questions about the most obvious possible causes for someone in my condition. Was I withdrawing from alcohol? Had I recently ingested any strong hallucinogenic street drugs? Then she went to work trying to bring my seizures to a halt.
In recent months, Eben IV had been putting me through a vigorous conditioning program for a planned father-son climb up Ecuador’s 19,300-foot Mount Cotopaxi, which he had climbed the previous February. The program had increased my strength considerably, making it that much more difficult for the orderlies trying to hold me down. Five minutes and 15 milligrams of intravenous diazepam later, I was still delirious and still trying to fight everyone off, but to Dr. Potter’s relief I was at least now fighting with both sides of my body. Holley toldLaura about the severe headache I’d been having before I went into seizure, which prompted Dr. Potter to perform a lumbar puncture—a procedure in which a small amount of cerebrospinal fluid is extracted from the base of the spine.
Cerebrospinal fluid is a clear, watery substance that runs along the surface of the spinal cord and coats the brain, cushioning it from impacts. A normal, healthy human body produces about a pint of it a day, and any diminishment in the clarity of the fluid indicates that an infection or hemorrhage has occurred.
Such an infection is called meningitis: the swelling of the meninges, the membranes that line the inside of the spine and skull and that are in direct contact with the cerebrospinal fluid. In four cases out of five a virus causes the disease. Viral meningitis can make a patient quite ill, but it is only fatal in approximately 1 percent of cases. In one case out of five, however, bacteria cause meningitis. Bacteria, being more primitive than viruses, can be a more dangerous foe. Cases of bacterial meningitis are uniformly fatal if untreated. Even when treated rapidly with the appropriate antibiotics, the mortality rate ranges from 15 to 40 percent.
One of the least likely culprits for bacterial meningitis in adults is a very old and very tough bacteria named Escherichia coli —better known simply as E. coli . No one knows how old E. coli is precisely, but estimates hover between three and four billion years. The organism has no nucleus and reproduces by the primitive but extremely efficient process known as asexual binary fission (in other words, by splitting in two). Imagine a cell filled, essentially, with DNA, that can take in nutrients (usually from other cells that it attacks and absorbs) directly through its
