SPG28


Presentation

  • Each entry follows a 5 section structure that will cover (1) essential features of the disorder (2) physiological basis of the disorder (3) neuropsychological and other clinical presentation (4) assessment and diagnostic practices (5) evidence-based treatments[books.google.com]
  • 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]
  • Since its first report from Québec, more than 100 disease-causing variants have been reported in ARSACS, with variable clinical presentation. MRI imaging may help establishing the clinical diagnosis, especially if typical changes are present.[oatext.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]
  • Muscle weakness when present is seen in iliopsoas, tibialis anterior and, to a lesser extent, the hamstrings.[jnnp.bmj.com]

Difficulty Walking
  • Progressive difficulty walking is the main problem and occurs due to taut and weak muscles. This manifests initially as stumbling, stubbing the toe, catching of the feet on uneven surfaces and sidewalks, clumsy gait, or difficulty with balance.[encyclopedia.com]
  • Most patients present with difficulty walking or gait disturbance, noticed either by themselves or a relative. In those with childhood onset, a delay in walking is not uncommon.[jnnp.bmj.com]
Hyperreflexia
  • People with this condition can also experience exaggerated reflexes (hyperreflexia), ankle spasms, high-arched feet (pes cavus), and reduced bladder control.[ghr.nlm.nih.gov]
  • […] 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]

Cognitive Deficit
  • This approach emphasizes the importance of looking at the other functional impacts of these manifestations (e.g. cognitive deficits secondary to depression, orthodopaedic ambulation issues).[books.google.com]
  • Patients with SPG3A and SPG4 have less disability and are less likely to develop cognitive deficits.[ng.neurology.org]

  • Given that both of these disorders are treatable, dopa-responsive dystonia should be excluded in a child with progressive gait disturbance and lower-extremity spasticity of unknown etiology, whereas arginase deficiency should be considered in a young[emedicine.medscape.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]

  • Primary lateral sclerosis The age of onset for primary lateral sclerosis (PLS) is usually between 40 and 60 years, with spasticity in the legs accompanied by hyperactive deep tendon reflexes, clonus, and Babinski sign.[emedicine.medscape.com]

Workup

  • While this adds considerable challenges in the diagnostic workup, certain specific complicating features may guide the differential diagnosis between the different HSPs.[scielo.br]
  • 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]

Prognosis

  • 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 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]
  • This distinction is important for genetic counseling of family members and for the patient’s prognosis, in that HSP generally carries a more favorable prognosis. [2] Other components of the differential diagnosis of HSP are similar to those of PLS.[emedicine.medscape.com]
  • Identification of the specific mutation concerned is essential to establishing a prognosis and providing satisfactory treatment and proper genetic counselling.[elsevier.es]

Etiology

  • Accordingly, plasma oxysterols are biomarkers that should be included in the screening of any spastic paraplegia of unknown etiology.[oxfordmedicine.com]
