Nerve cells demonstrate not only storage of cholesterol but also neurofibrillary tangles containing paired helical filaments, similar to the neurofibrillary tangles present in Alzheimer disease seeKufs disease seeDown syndrometuberous sclerosis seeprogressive supranuclear palsyand neurodegeneration with brain iron accumulation-1 NBIA1;among others. Complementation studies in Niemann-Pick disease type C indicate the existence of a second group.

They gave brief reports of 6 adult-onset cases.

Evidence of an enzymatic deficiency in Niemann-Pick diseae. Owing to the low number of clinical trials assessing Jiemann treatment and the lack of additional information, it is not yet possible to make a comparison between the different types of treatments for this disease. Age of onset ranged from the neonatal period to 55 years. The authors suggested that NPC1 gene mutations combined with homozygosity of APOE4 alleles leads to pathology similar to that found in Alzheimer disease.

Always seek the advice of your physician or other qualified health provider prior to starting any new enfermdad or with questions regarding a medical condition. The authors concluded that Npc1 deficiency leads to cell-autonomous, selective neurodegeneration and suggested that the ataxic symptoms of NPC disease may arise from Purkinje cell death rather than cellular dysfunction.
