Summary. Hereditary spastic paraplegia (HSP) is a group of hereditary, degenerative, neurological disorders that primarily affect the upper motor neurons. Upper motor neurons in the brain and spinal cord deliver signals to the lower motor neurons, which in turn, carry messages to the muscles.
Aug 15, 2000 · Hereditary spastic paraplegia (HSP) can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner or by maternal (mitochondrial) inheritance, depending on the genetic subtype in a family.
Hereditary spastic paraplegia is a group of rare hereditary disorders characterized by progressive, spinal, nonsegmental spastic leg paresis, sometimes with intellectual disability, seizures, and other extraspinal deficits. Diagnosis is clinical and sometimes by genetic testing. Treatment is symptomatic, including medications to relieve spasticity.
Hereditary (familial) spastic paraplegia is a group of rare hereditary disorders that cause gradual weakness with muscle spasms (spastic weakness) in the legs. People with hereditary spastic paraplegia have exaggerated reflexes, cramps, and spasms, making walking difficult.
Feb 1, 2022 · Abstract. Hereditary spastic paraplegia (HSP) is a rare neurodegenerative disorder with the predominant clinical manifestation of spasticity in the lower extremities. HSP is categorised based on inheritance, the phenotypic characters, and the mode of molecular pathophysiology, with frequent degeneration in the axon of cervical and thoracic ...
What is hereditary spastic paraplegia? Hereditary spastic paraplegia (HSP) refers to a group of over 80 different genetic conditions that present with progressive spasticity (muscle tightness) and weakness. Many forms of HSP are rare or even ultra-rare diseases.
Mar 10, 2021 · Hereditary spastic paraplegias (HSPs) are a group of rare, inherited, neurological diseases characterized by broad clinical and genetic heterogeneity. Lower-limb spasticity with first motoneuron involvement is the core symptom of all HSPs.
