What are the symptoms of Niemann-Pick type C disease?
Symptoms of Niemann-Pick type C disease (NP-C) are varied and may appear in infants as young as a few months old, or in late adulthood. Typically, NP-C presents in mid-to-late childhood, and common symptoms include:1,2
Children with NP-C may appear clumsy and suffer frequent falls. The progressive physical and intellectual disability, and difficultly communicating, means that these children perform poorly at school and may be labeled as badly-behaved.1 The build up of fatty molecules (lipids), particularly in the brain, causes the neurological symptoms of NP-C. Symptoms in the very young are hard to detect.1 Most infants have severe liver damage and some experience breathing difficulties. Adults tend to present with intellectual decline and eye movement problems.1
