[Organic dementia as a first symptom of infantile Huntington's chorea (author's transl)]

A loss of intellectual capacity at the age of 10 was the first symptom in a case of infantile Huntington's chorea. Subsequently a rigid hypokinetic syndrome occurred only at the age of 20. The dementia syndrome was confirmed in psychological tests. Auxiliary findings such as a diffuse abnornal EEG, as well as a dilatation of the lateral ventricles and an extension of the subarachnoid spaces in the PEG corresponded to a positive diagnosis of Huntington's chorea.
