  Diagnosis HSP is diagnosed by the following: 1) typical symptoms (lower extremity spastic weakness that may be non-worsening (early childhood onset) or slowly progressive over many years; 2) findings on neurologic examination (lower extremity hyperreflexia [rarediseases.org]

  Pure HSPs are characterized by slowly progressive lower extremity spasticity and weakness, corticospinal tract signs, variable hypertonic urinary disturbances, and mild reduction of lower extremity vibration sense and proprioception. [ng.neurology.org]

Our findings confirm that this is indeed not an uncommon presentation of this disorder and we suggest that SPG7 gene analysis should be included in the diagnostic workup of autosomal recessive PEO, especially if spasticity is present. [journals.plos.org]

Diagnosis and Prognosis: The diagnosis is usually made by a neurologist. The MRI may show some loss of tissue in certain areas of the brain but this is nondiagnostic. [disorders.eyes.arizona.edu]

Prognosis [ edit ] Although HSP is a progressive condition, the prognosis for individuals with HSP varies greatly. It primarily affects the legs although there can be some upperbody involvement in some individuals. [en.wikipedia.org]

Prognosis: predicting symptoms and course of HSP As noted above, there is significant variation in HSP symptoms and their severity. This limits the certainty of making predictions. [rarediseases.org]

Identification of the specific mutation concerned is essential to establishing a prognosis and providing satisfactory treatment and proper genetic counselling. [elsevier.es]
