Familial spastic paraplegia.

Familial spastic paraplegia (FSP) was recorded in three families. The pattern of familial transmission and the onset in the second and third decade of life strongly suggested autosomal dominant inheritance. FSP in this series showed the consistent, classical, clinical features with some inconstant findings (nystagmus, dysarthria, posterior column involvement). Baclofen for the treatment of spasticity is beneficial in this condition and genetic counselling should be considered.
