Although Batten disease is the juvenile form of NCL, most doctors use the same term to describe all forms of NCL. Early symptoms of Batten disease (or NCL) usually appear in childhood when parents or doctors may notice a child begin to develop vision problems or seizures. In some cases the early signs are subtle, taking the form of personality and behaviour changes, delayed speech, slow learning, clumsiness or stumbling.
The symptoms of these childhood types are similar to those caused by Batten disease, but they become apparent at different ages and progress at different rates. 1  Congenital NCL is a very rare and severe form of NCL. Babies have abnormally small heads (microcephaly) and seizures, and die soon after birth.
