Abstract
Niemann-Pick disease type C (NPC), is a rare lysosomal storage disorder, which has a variable presentation based on the age of onset. We describe five adult/adolescent-onset NPC cases presenting with a range of movement disorders along with vertical supranuclear gaze palsy as part of the clinical presentation. A diagnostic delay of 4-17 years from the symptom onset was found in this case series. A high index of clinical suspicion in adult/adolescent patients presenting with vertical supranuclear gaze palsy along with various movement disorder phenomenology can help in the early diagnosis of NPC.
