Hereditary Spastic Paraplegia (HSP), also known as Strümpell-Lorrain disease or Familial Spastic Paraplegia, is a group of inherited neurological disorders characterized by progressive weakness and spasticity of the lower limbs. Historical and Alternative Nomenclature Because Hereditary Spastic Paraplegia manifests in diverse genetic forms, it has historically been described by various names. You may encounter the term Strümpell-Lorrain disease in older medical literature, named after the clinicians who first described its clinical features.

Hereditary Spastic Paraplegia (HSP), also known as Strümpell-Lorrain disease or Familial Spastic Paraplegia, is a group of inherited neurological disorders characterized by progressive weakness and spasticity of the lower limbs.
Historical and Alternative Nomenclature
Because Hereditary Spastic Paraplegia manifests in diverse genetic forms, it has historically been described by various names. You may encounter the term Strümpell-Lorrain disease in older medical literature, named after the clinicians who first described its clinical features. Other historical or descriptive synonyms include Familial Spastic Paraplegia and Hereditary Spastic Paraparesis. While these terms are often used interchangeably, "paraplegia" generally implies more severe motor impairment, while "paraparesis" suggests a milder degree of weakness.
Official Classifications
In modern clinical practice, the term Hereditary Spastic Paraplegia is the standard nomenclature used by organizations like the NIH Genetic and Rare Diseases Information Center (GARD) and Orphanet. In the OMIM (Online Mendelian Inheritance in Man) database, the condition is categorized under a vast array of SPG (Spastic Paraplegia Gene) numbers, reflecting the over 80 distinct genetic loci identified to date. The ICD-10 classifies these under G11.4 (Hereditary spastic paraplegia).
Why Multiple Names Exist
The existence of multiple names for Hereditary Spastic Paraplegia stems from the rapid evolution of genetic research. Initially, the disease was classified solely by its clinical presentation. As our understanding of the underlying genetic mutations expanded, the medical community shifted toward identifying specific subtypes (e.g., SPG4, SPG7) rather than using a single umbrella term. This shift allows for more precise diagnostic pathways and tailored clinical care. Despite these genetic advancements, Hereditary Spastic Paraplegia remains the most widely recognized and preferred term among neurologists and patient support groups worldwide to ensure consistency in medical records and research literature.
