A recent study has found evidence that the difference in seasons may also trigger a difference in the effects of multiple sclerosis, a disease which makes the immune system begin to harm the brain and spinal cord, according to The Los Angeles Times.

This discovery comes on the heels of a new analysis of old X-rays. Scientists looked for newly-developed T2 lesions in 939 MRI exams, taken from 44 different patients, from 1991 to 1993.

They concluded that the disease became worse during the summer, as symptoms were apparently affected by solar radiation and temperature. From March to August, it appeared that patients suffering from multiple sclerosis were two to three times more likely to develop new brain lesions than any other time during the year.

Anne Cross, a neurologist who wrote an editorial on the study, said that these findings have implications on the seasonal variability of the condition, offering "important clues regarding the mechanisms of disease progression in MS."

The Neurology Channel claims that chronic conditions, such as multiple sclerosis, are often more effectively cured through the use of alternative medicines and therapy, which can reduce inflammation. Exercise can also help reduce symptoms of the disease.
