[Inborn and induced lipidosis. Differential diagnosis].

The drugs used for the treatment of psychiatric disorders sometimes produce neurological symptoms (drug-induced lipidosis) similar to those found in subjects with genetic disorders of lipid metabolism. We report the case of a young man with Niemann-Pick disease first treated for behavioural disorders. As the family accused the Medical Department to be responsible for a disease caused by excess of medication, a detailed study of the patient's biochemical features was used to refute the complaint.
