A rare neuronal ceroid lipofuscinosis characterized by developmental and motor regression, seizures, ataxia, intellectual disability, delayed global development, speech and language, spasticity, and hypotonia. Visual impairment is not always present. It may present with late infantile (5-7 years), juvenile (4-8 years) or adult-onset (30 years). Progressive myoclonus epilepsy, with myoclonic and tonic-clonic seizures, limb weakness, dysarthria are mainly associated with the adult-onset form of the disease and these patients commonly have photosensitivity (sometimes extreme) whereas vision loss is infrequent.
