The high-fat ketogenic diet can dramatically reduce or completely eliminate debilitating seizures in most children with infantile spasms, whose seizures persist despite medication, according to a Johns Hopkins Children's Center study published online April 30 in the journal Epilepsia.
Infantile spasms, also called West syndrome, is a stubborn form of epilepsy that often does not get better with antiseizure drugs. Because poorly controlled infantile spasms may cause brain damage, the Hopkins team's findings suggest the diet should be started at the earliest sign that medications aren't working.
"Stopping or reducing the number of seizures can go a long way toward preserving neurological function, and the ketogenic diet should be our immediate next line of defense in children with persistent infantile spasms who don't improve with medication," says senior investigator Eric Kossoff, M.D., a pediatric neurologist and director of the ketogenic diet program at Hopkins Children's.
The ketogenic diet, made up of high-fat foods and few carbohydrates, works by triggering biochemical changes that eliminate seizure-causing short circuits in the brain's signaling system. It has been used successfully in several forms of epilepsy.
A small 2002 study by the same Hopkins team showed the diet worked well in a handful of children with infantile spasms. The new study is the largest analysis thus far showing just how effective the diet can be in children with this condition.
Of the 104 children treated by the Hopkins team, nearly 40 percent, or 38 children, became seizure-free for at least six months after being on the diet for anywhere from just a few days to 20 months. Of the 38, 30 have remained so without a relapse for at least two years.
After three months on the diet, one-third of the children had 90 percent fewer seizures, and after nine months on the diet, nearly half of the children in the study had 90 percen
