A medical mystery in California has left at least five children suffering from a rare illness that is debilitating.
"All of the children have permanent weakness in their severely affected limbs," says Dr. Keith Van Haren, a pediatric neurologist at Stanford University.

The problem is, they're not sure what it is, or how to treat it.
We'll keep you posted as doctors come together nationwide to try to indent this illness. @
