Presentation
HSP can be classified as pure or uncomplicated if no additional findings are present (2). Age of onset of HSP can range from early childhood to late adulthood. [dnatesting.uchicago.edu]
HSP is classified according to the clinical phenotype as either pure or complex, the latter presenting with neurological and systemic impairments in addition to spastic paraparesis. [journals.lww.com]
RESULTS Six patients from two families presented with a slowly progressive, autosomal recessive, spastic tetraplegia. [jnnp.bmj.com]
Dysarthria and bladder dysfunction are often present. Cerebellar ataxia is common and some patients first present with this as a prominent sign in the first and second decades. [disorders.eyes.arizona.edu]
The sister carrying the R294H variant had an ataxic gait and hand tremor at 3 years, which was not present in her sister. [epilepsygenetics.net]
Neurologic
- Hyperreflexia
The gait is spastic with weakness, hyperreflexia, and extensor plantar responses in the lower limbs. The upper limbs are variably involved and movements are dysmetric. Dysarthria and bladder dysfunction are often present. [disorders.eyes.arizona.edu]
[…] spasticity is increased at the hamstrings, quadriceps and ankles Weakness is most notable at the iliopsoas, tibialis anterior, hamstring muscles difficulty in walking, decreased vibratory sense at the ankles, and paresthesia In lower extremities hyperreflexia [slideshare.net]
Hyperreflexia of the lower as well as the upper limbs was also observed. Brain MRI findings were similar to that of patient II3. [omicsonline.org]
Examination at the age of 22 years after a traffic accident revealed failure of abduction of the left eye, hyperreflexia in all four extremities and Babinski sign. [journals.plos.org]
Diagnosis of SPG is established by the following clinical features 1, 2 : Typical clinical symptoms of spastic gait impairment and neurologic findings of spastic weakness, hyperreflexia, typically associated with bilateral extensor plantar responses A [centogene.com]
- Babinski Sign
Examination at the age of 22 years after a traffic accident revealed failure of abduction of the left eye, hyperreflexia in all four extremities and Babinski sign. [journals.plos.org]
Detailed neurological examination showed predominantly bilateral proximal pronounced paresis (3/4) of the lower limbs with hyperreflexia and positive bilateral Babinski sign. He also complains about urinary urgency. [omicsonline.org]

- Abnormal Gait
They all developed an abnormal gait between 13 and 23 years of age and progressed to using a wheelchair within three to 21 years. [jnnp.bmj.com]

Workup
It is divided into the following sections: Overview Differential Diagnoses & Workup Treatment & Medication Follow-up Multimedia [hspersunite.org.au]
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]
Treatment
Treatment Treatment Options: No effective treatment is known for the neurological deficits but cataract surgery may be beneficial for visually significant cataracts. [disorders.eyes.arizona.edu]

However, HSPers report benefits from treatments as diverse as ankle / foot surgery where tendons are relocated, to fitness and specialised treatment from neurophysiotherapists for muscle strength and range of motion. [hspersunite.org.au]
Gene therapy may not work against all types of genetic disease, and it remains to be seen if any of the HSPs are candidates for this type of treatment. [medschool.lsuhsc.edu]
Prognosis
Determining the molecular basis of disease using genetic testing can be useful in predicting prognosis and disease course, and can aid in identification of at-risk family members. [dnatesting.uchicago.edu]
Abstract Although SPG11 is the most common complicated hereditary spastic paraplegia, our knowledge of the long-term prognosis and life expectancy is limited. [nature.com]
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]
[…] inversely correlated with quality of life in a previous study. 31 As the majority of patients in our cohort who met the clinical criteria for HSP did not have a genetic diagnosis, this illustrates the need for studies of clinical parameters which influence prognosis [ng.neurology.org]
Etiology
Hereditary Spastic Paraplegia Etiology HSP is a highly genetically heterogeneous group of disorders (4). 70-80% of HSP is inherited in an autosomal dominant manner, and the majority of dominant HSP is classified as uncomplicated or pure HSP (2). [dnatesting.uchicago.edu]

Pathophysiology
Pathophysiology [ edit ] The major feature of HSP is a length dependent axonal degeneration. [21] These include the crossed and uncrossed corticospinal tracts to the legs and fasciculus gracilis. [en.wikipedia.org]
Prevention
Treating hereditary spastic paraplegia It isn't possible to prevent, slow or reverse hereditary spastic paraplegia, but some of the symptoms can be managed so that day-to-day activities become easier. [nhs.uk]

For patients with walking (gait) problems, canes, walkers, and wheelchairs will facilitate mobility and help to prevent falling and subsequent injury. A number of drugs are available to reduce some of the symptoms of HSP. [medschool.lsuhsc.edu]
