Hereditary spastic paraplegia is a rare form of motor system disease w
ith autosomal dominant or recessive inheritance. Onset in childhood or
youth is characteristic and serves as a diagnostic feature. We saw a
family with the autosomal dominant type of SP and first symptoms prese
nting at around 60 years of age. Hence the hereditary disorder has to
be considered as one of the differential diagnoses of spastic parapleg
ia even in adults at an advanced age, the family history gaining speci
al importance.
