Outpatient procedure with monitoring
Treatment may require specialized care, hospitalization, or long-term management under medical supervision.
Progressive vision impairment management
Systematic monitoring of visual function with early implementation of low vision aids, communication adaptations, and environmental modifications as vision deteriorates.
Additional treatment options
Ketogenic diet consideration
Some patients with NCL may benefit from ketogenic diet under specialist supervision, potentially providing anticonvulsant effects and supporting mitochondrial function.
dietaryBehavioral and communication support
