Though MS is less common in people under the age of 18, a new study found children who are diagnosed with the condition could be more likely to suffer memory or attention problems. Childhood onset of MS might also be linked to lower IQ scores, according to an article published in the May 13 issue of Neurology.

Researchers compared 63 children diagnosed with MS to 57 healthy children. Thirty-one percent of the children with MS failed three of the cognitive tests researchers gave them, meeting the study’s criteria for impairment. Some children also had problems with language.

A significant number of the children with MS had lower IQ scores than the healthy children, and more than half had difficulties in school or with everyday activities.

Children in the study who developed MS earlier in life were more likely to have lower IQ scores, researchers concluded.

While cognitive problems are associated with MS in adults, as well, the children’s diagnosis might not be the only thing to consider where thinking skills are concerned, said MSF Medical Advisor Dr. Ben Thrower.

"There could be factors other than MS involved," he said. "It is possible medications, missed school and psychosocial stressors could contribute to some cognitive issues in these kids."
