Warm weather is known to aggravate multiple sclerosis, increasing the number of lesions that develop in the brain and spinal cord and leading to a flare-up of symptoms such as numbness and fatigue. But a new study shows that warm weather can also impair cognitive function.
The study, which will be presented in April at the annual meeting of the American Academy of Neurology, examined 40 people with the disease and 40 healthy people. The researchers, from the Kessler Foundation in West Orange, N.J., found that people with multiple sclerosis scored 70% better on thinking tests during cooler days as compared with warmer days. There was no difference in test scores linked to weather conditions for healthy people.

“Neurologists believe the interventionalists are overstating the possible value of CCSVI and that commercial interests are overriding scientific inquiry,” according to Dr. Burks, a neurologist and clinical professor of medicine at the University of Nevada, Reno. Patients, armed with anecdotal evidence downloaded from the Internet, are certain that CCSVI surgery is the miracle they’ve been waiting for and perceive the hesitancy of U.S. and Canadian neurologists to embrace the treatment as evidence of a possible conspiracy with pharmaceutical companies who stand to lose billions of dollars if the surgery becomes a first-line treatment, he said. Further, he noted, advocates of CCSVI claim that neurologists who refuse patients’ demands for diagnostic testing and surgical referral for CCSVI are jeopardizing the safety of those patients, who are traveling to foreign countries such as Poland, Bulgaria, Mexico, Costa Rica, and India to get the care that they cannot receive in North America.
Both camps point to the much publicized case of a Canadian MS patient who traveled to Costa Rica for jugular vein angioplasty and died from a ruptured vessel as evidence that supports their respective positions, said Dr. Burks.
To date, the majority of the evidence regarding CCSVI diagnosis and treatment in MS is inconsistent, and can be confusing, Dr. Burks noted.
