Summary Hereditary spastic paraplegia (HSP) is a general term for an expanding group of rare genetic disorders characterized by slowly progressive weakness (paraplegia) and increased muscle tone and stiffness (spasticity) of leg muscles. The age of onset, rate of progression, associated symptoms, degree of muscle weakness and spasticity, and overall severity of HSP can vary greatly from one person to another, even among individuals with the same subtype or among individuals within the same family. HSP is classified as "pure" or "uncomplicated" if the symptoms are primarily confined to the aforementioned lower limb weakness and spasticity. Other symptoms can occur in the pure subtypes including bladder dysfunction or abnormal sensations in the lower legs or feet. HSP is classified as "complex" or "complicated" if additional symptoms are present such as an inability to coordinate voluntary movements (ataxia), seizures, intellectual disability, skin disease, dementia, and hearing and vision abnormalities. Individual forms of HSP are caused by a mutation to a specific gene. HSP can be inherited as autosomal dominant, autosomal recessive or X-linked condition.
Introduction HSP was first reported in the medical literature in the 1880s by a German doctor named Adolph Strumpell. A French doctor named Maurice Lorrain provided further detailed descriptions of the disorder shortly thereafter. More than 50 different forms of HSP have been identified in the ensuing years. Several different names have been used to describe these disorders. Recently, researchers have proposed a classification system that names each subtype by the official abbreviation SPG and a number (e.g. SPG1). The subtypes a numbered in the order they were identified in the medical literature. HSPs are a rapidly growing disease family and information about these disorders is constantly changing.
