Presentation
Concise Neurology presents neurology content in a logical sequence within each of ten chapters. [books.google.es]
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]
The risk of an individual inheriting the abnormal gene depends on the mode of transmission and whether the mutated gene is present on a sex chromosome or an autosome. [encyclopedia.com]
If the production of the normal or the abnormal transcript were gender dependent, it might provide an explanation for the sex difference observed in the present family. [jmg.bmj.com]
However, evidence of spasticity may be present in children under 1 year of age. Some patients have normal mental functions while others are considered mentally retarded. [disorders.eyes.arizona.edu]

- Lower Extremity Spasticity
Get Update Overview The hereditary spastic paraplegias (SPG) are a group of clinically and genetically diverse disorders characterized by progressive, usually severe, lower extremity spasticity; see reviews of {5:Fink et al. (1996)} and {4:Fink (1997) [diseaseinfosearch.org]
Clinical Features Symptoms depend on the type of HSP inherited Main feature >>> progressive spasticity in the lower limbs, due to pyramidal tract dysfunction In the lower extremities, spasticity is increased at the hamstrings, quadriceps and ankles [slideshare.net]
Different genetic loci for autosomal recessive, autosomal dominant, and x-linked forms of hereditary spastic paraplegia have been identified. Clinically, patients present with slowly progressive distal limb weakness and lower extremity spasticity. [reference.md]
All forms of HSP, complicated and uncomplicated, share the primary symptom of lower-extremity spastic weakness. [invitae.com]
Non-syndromic spastic paraplegias are characterized by slowly progressive spasticity and weakness of the lower extremity, often associated with hypertonic urinary disturbances, mild reduction of lower extremity vibration sense and, occasionally, of joint [blueprintgenetics.com]
- Hyperreflexia
[…] 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]
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]
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]
All of them started with symptoms consisting of gait difficulties and weakness in the lower extremities, and their neurologic examination showed an upper motor neuron syndrome predominantly in the lower extremities with weakness, spasticity and hyperreflexia [ajnr.org]

Workup
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: Mobility devices and physical therapy can be helpful, especially in younger individuals. [disorders.eyes.arizona.edu]

Prognosis
Prognosis 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. [ipfs.io]
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]
Prognosis This varies widely, but most often HSP is compatible with a normal life expectancy. The rate of progression varies considerably and is influenced by the mode of inheritance. [encyclopedia.com]

Pathophysiology
The book presents higher level content than the student "In a Page" text, covers each topic in more depth, and addresses issues related to pathophysiology and neuropathology of diseases. [books.google.es]
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]
Such ï¬ndings could evolve to become a valuable parameter, together with neuroimaging and other biomarkers, to help better understand the pathophysiology of the disease. Author contributions. [redalyc.org]
