The initial version of this article overstated the rate at which neurosurgeons and spouses of Alzheimer's patients develop the dementia. The risk is nearly 2 1/2 times greater for neurosurgeons, not sevenfold, and 1.6 times higher for spouses, not six times greater. On Sept. 18, the article was changed to say that the risk for neurosurgeons was a comparison with the general population, not other causes of death for the doctors."
