Patients present with hypotonia, loss of previously acquired motor milestones and cognitive skills, ataxia, nystagmus, tremor, seizures, tetraparesis, and respiratory failure, eventually resulting in a vegetative state. Imaging of the brain and spinal cord may show white matter abnormalities, cerebral atrophy, cerebellar edema, and spinal myelopathy.
