Symptoms of multiple sclerosis more severe in summer months

Results of a new study seem to point to symptoms associated with multiple sclerosis being stronger in spring and summer than fall and winter.

We know that multiple sclerosis is a neurological disease but when it comes to why it would become more severe during the warmer part of the year, the answer remains a mystery.

For their study the researchers examined brain scans of patients with multiple sclerosis at various times of year, comparing them to the brain scans of healthy people.

They noticed that during the spring and summer months, lesions on the brain associated with MS nearly doubled compared to fall and winter.

“Our results showed that the appearance of lesions on brain scans was two to three times higher in the months of March to August, compared to other months of the year,” said study author Dominik Meier of Brigham and Women’s Hospital in Boston.

This study finding could mean that certain drugs given to people with MS could react differently depending on the time of year they were given.
