The analysis included epilepsy surgical outcomes between 1988 and 1998. Patient follow-up reviews ranged in one to 14 years, with the average length of six years. Outcomes will be presented April 27 at the American Academy of Neurology annual conference in SAN FRANCISCO BAY AREA by Gregory Cascino, M.D., chair of the Mayo Clinic Division of Epilepsy, Section of Neurology. The surgery involves getting rid of the epileptic human brain tissue, a procedure known as a focal cortical resection. Partial epilepsy may be the most common seizure disorder, impacting over one million individuals in the United States and comprising 90 % of adult epilepsy cases. Cascino. Need for the Mayo Clinic Findings Intractable partial epilepsy has long been regarded as specifically disabling.The researchers excluded 11 days which air pollution surpassed 40 micrograms per cubic meter. They found that the estimated odds ratio of stroke onset was 1.34 following a 24-hour period where quality of air was classified as moderate weighed against a similar, good-air quality timeframe. When they looked at the kind of particulate matter, the researchers determined that the chance was more strongly associated with traffic pollution, such as black NO2 and carbon, versus non-traffic associated particulate matter. Air pollution and cognitive decline Weuve and colleagues examined data from 19, 049 women aged 70 years or older without a past history of stroke, who participated in the Nurses Health Research between 1995 and 2001 and agreed to undergo cognitive testing.
