Abstract
A follow-up investigation of 24 patients with hereditary spasticity in a geographically isolated northern Swedish population, first examined by Book (1953), was performed. Fifteen of them were dead. During the period from 1950-1972 five new cases of spastic syndromes were diagnosed in this population. The patterns of clinical symptoms and the genetic associations between the new and 24 previously reported patients with spastic syndromes were analyzed. Three of the five new cases had a specific syndrome. This starts in the first years of life with ataxia, which is followed by dysarthria, spasticity and jerky intention tremor. Initially the patients are mentally normal, but there seems to be slight mental deterioration through the years. The disorder is a progressive spinocerebellar degeneration with autosomal recessive inheritance.Keywords
