An April 18 Health item incorrectly summarized the findings of a study on the effects of blood pressure drugs on dementia in the elderly. It should have said that men in the study with untreated high blood pressure showed greater cognitive decline than did men with normal blood pressure or hypertension that had been treated for at least five years.

· THE QUESTION Many people can keep epilepsy in check by taking medication, but others have seizures that drugs can't control. Might surgery to remove the area of the brain causing the seizures help people with intractable epilepsy?
· THIS STUDY involved 399 people who had epilepsy surgery after having had seizures for an average of 20 years. Six months after surgery, 81 percent of the participants were seizure-free or nearly so; after 10 years, 72 percent rarely if ever had seizures. People aged 18 to 40 had better results than other people. Those whose surgery involved the temporal lobe fared better than those who had surgery on other regions of the brain.
· WHO MAY BE AFFECTED BY THESE FINDINGS? People with epilepsy, which affects about 3 million Americans. The authors report that as many as 40 percent of epileptics have seizures that cannot be controlled solely by medication.
· CAVEATS Not all people with epilepsy are good candidates for surgery. Results may vary depending on the expertise of the surgeon.
· FIND THIS STUDY April issue of the Journal of Neurosurgery; article available online at http:/

The research described in Quick Study comes from credible, peer-reviewed journals. Nonetheless, conclusive evidence about a treatment's effectiveness is rarely found in a single study. Anyone considering changing or beginning treatment of any kind should consult with a physician.
