NPD type B is a rare inborn error of metabolism, with a benign course and prognosis, while types A and C are always associated with severe neurological involvement. [ncbi.nlm.nih.gov]

Its onset is usually in late childhood and is much less severe than NPD-A, with a good prognosis of survival into adulthood. [radiopaedia.org]

Prognosis of type C depends on the time of onset of symptoms; the earlier the appearance of symptoms, worse is the prognosis. Patients with late onset of symptoms have survived up to 20 years of age. [medindia.net]
