Ceroidal Neuronal Lipofuscinosis (CLN): Developmental Trajectories

Neuronal ceroid lipofuscinosis (CLN), commonly called Batten disease, group together a group of rare lysosomal-based neurodegenerative disorders characterized by the intralysosomal accumulation of fluorescent ceroid lipofuscin material.

Common Path of Symptoms

  • Progressive and rapid loss of visual acuity leading to blindness (often the first sign).
  • Myoclonic and focal epileptic seizures refractory to pharmacological treatment.
  • Progressive regression of cognitive (dementia) and motor milestones.
  • Generalized motor impairment with profound spasticity and premature death.
