Hereditary spastic paraplegia.

Hereditary spastic paraplegia is a genetically transmitted disease that is usually autosomal dominant. Characterized by a slow progression of spastic paraparesis, it is frequently misdiagnosed as cerebral palsy. Our experience consists of six families with a total of 26 affected members. All initial referrals were children with a slowly progressive paraplegia. Each child was noted to have slightly delayed motor milestones, normal intellect, and no history of perinatal cerebral event. Each child was treated when necessary with appropriate tendon lengthenings. Recognition is the key to management. A careful patient and family history will reveal the hereditary nature of the disease and help develop treatment plans.
