Dr. John K. Fink, a leading researcher into HSP, gives an overview of the status quo in terms of classification, diagnosis, testing and treatment.
HSP is classified according to:
- the mode of inheritance,
- the HSP locus when known, and
- whether the spastic paraplegia syndrome occurs alone or is accompanied by additional neurologic or systemic abnormalities.
Diagnosis & Testing
Hereditary spastic paraplegia is a clinical diagnosis for which laboratory confirmation is sometimes possible. Careful exclusion of alternate and co-existing disorders is an important element in HSP diagnosis. Analysis of 11 recently discovered HSP genes provides insight into HSP pathogenesis.
Prenatal genetic testing in HSP is possible for some individuals with the increasing availability of HSP gene analysis.
Treatment for HSP is presently limited to symptomatic reduction of muscle spasticity, reduction in urinary urgency, and strength and gait improvement through physical therapy.
