title: [Neurological manifestations of type 1 Gaucher's disease: Is a revision of disease classification needed?].
abstract: BACKGROUND
  Gaucher's disease (GD), the most prevalent inherited lysosomal storage disorder, is caused by deficient glucocerebrosidase activity. The resulting accumulation of glucocerebrosides in lysosomes of macrophages leads to hepatosplenomegaly, anemia, thrombocytopenia, and various bone manifestations. Gaucher's disease is classified into 3 types based on the nature of its effects on the central nervous system. Type 1, the most common variant, is classically nonneuronopathic. However, the occurrence of Parkinsonism seems to be more frequent in type I Gaucher's disease than in the general population. Furthermore, heterozygotes for certain glucocerebrosidase gene mutations have a higher risk to develop Parkinson's disease.
  
  
  METHODS
  We report our experience about 9 patients with Gaucher's disease and their association with neurological manifestations.
  
  
  CONCLUSIONS
  These recent data may discuss Gaucher's classification and the existence of a continuum between neurologic and non-neurologic forms of the disease.
