Juvenile Batten disease is a fatal, genetic disorder of the central nervous system that begins in childhood. Early symptoms of this disorder appear between the ages of 5 and 10 years, when parents or physicians may notice a previously normal child has begun to develop vision problems or seizures. In some cases the early signs are subtle, taking the form of personality and behavior changes, slow learning, clumsiness, or stumbling. Over time, affected children suffer cognitive impairment, worsening seizures, and progressive loss of vision, motor skills and the abilities to eat and initiate elimination.
Eventually, children with Batten disease become blind, bedridden, and demented. Batten disease is fatal by late teens or early twenties.
