Hereditary Spastic Paraplegia

Hereditary spastic paraplegia (HSP) is a rare hereditary disorder and becomes clinically apparent during adolescence or in childhood and progresses s1owly throughout the adult years with a variability in the severity of expression. We experienced 3 cases of hereditary spastic paraplegia. Cases 1 and 2, which were pure HSP, had only the signs and symptoms of corticospinal tract involvement with the positive family history, and case 3, which was a complicated case of HSP, had distal muscle wasting, dysarthria, signs and symptoms of the corticospinal tracts, and a positive family history. All are thought to be inherited in an autosomal dominant pattern.
