[Sporadic juvenile forms of Huntington's chorea]

Abstract

Six patients with Huntington's chorea in the age of 15-24 years old, suffered from diffusive choreic hyperkynesis with slowly progressive dementia. The development of this disease in childhood and adolescence was atypical, as nobody in the family and in kin sufferred from it and it was difficult to diagnose the disease. Recognition of the disease was promoted by pneumoencephalography, electromyography and memory investigation.
