[Iatrogenic neurological disorders in old people: a review].
Aged people are frequently the victims of iatrogenic diseases, especially adverse effects of drugs since they are affected by many age-related diseases and are given many drugs. Geriatric medicine in Japan has a bitter history of having produced many victims by adverse effects of cerebral vasodilators and cerebral stimulants; they included parkinsonism and depression induced by flunarizine and cinnarizine, and Reye-like encephalopathy induced by calcium hopantenate. Parkinsonism induced by sulpiride, tiapride, metoclopramide or atypical anti-psychotics, dyskinesia induced by anti-parkinsonian drugs or anti-psychotics, and psychotic symptoms induced by anti-parkinsonian drugs, anti-cholinergic drugs, anti-depressants or histamine H2 antagonists are still very common. Wernicke encephalopathy caused by intravenous glucose infusion without thiamine, central pontine myelinolysis by too rapid correction of hyponatremia are important though infrequent. Iatrogenic Creutzfeldt-Jakob disease by dura grafts is a warning against the easy use of medical materials produced with human organs or blood. Iatrogenic diseases are preventable, and geriatricians have to pay attention to the information on adverse effects of drugs and medical materials and carefully observe the early signs of iatrogenic diseases.
