[Clinical characteristics of the neurological forms of Gaucher's disease].

Gaucher's disease is the most prevalent disease of accumulation of glycosphingolipids. Neurological involvement is used to classify the different types of the disease. Type 1 affects approximately 90% of patients, and visceral manifestations and bone marrow, without affecting the nervous system. Type 2 is considered a severe form of disease with severe nervous system and death within two years. Type 3 is late, slowly progressive neurological symptoms and survival until the third decade. Besides these classical syndromes, the best knowledge of the disease related to the existence of national registries, the increased survival of patients resulting from replacement therapy, and demonstration of the behavior of glucocerebrosidase mutations as a risk factor of neurodegenerative diseases, has expanded the clinical phenotype and altered the traditional classification of the disease.
