Multiple sclerosis is an autoimmune disease that causes inflammation and affects the central nervous system. Weatherwise magazine reports that researchers at the Keesler Foundation in New Jersey believe those with MS may find it harder to learn, remember or process information on warmer days of the year. Previous studies have linked warmer weather to increased disease activity and lesions with people with MS. The Foundation conducted a study of 40 people with MS and 40 without and the tests measured learning, memory and the speed in which information was processed. Brain scans were incorporated into the process and the daily temperature on testing days was also noted. Those with MS scored 70 percent better on thinking tests during cooler days compared with warmer days. Fastcast: Warm, spotty showers.

Partly sunny, with a high near 85 degrees. Easterly wind between 10 and 15 mph. Tonight, a 20 percent chance of showers and thunderstorms. Mostly cloudy, with a low about 64 degrees. Easterly wind around 5 mph.
