Q. What is HSP? - A. HSP is a group of rare neurological conditions.

These conditions can be known as:

  • Hereditary Spastic Paraplegia,  Hereditary Spastic Paraparesis (HSP),
  • Familial Spastic Paraplegia,  Familial Spastic Paraparesis (FSP),
  • Idiopathic Spastic Paraparesis or
  • Strumpell-Lorraine Syndrome.

Genetic abnormalities reduce the levels of signals along the spinal cord. This causes slowly progressive stiffness (spasticity) and weakness of the lower limbs. The first symptoms for most people are stiffness and weakness of the legs possibly followed years later by a scissoring spastic gait. As a result of this spasticity, HSP affected people expend a much greater level of effort than an able bodied person in walking. Bladder problems and fatigue are often associated with the condition.

The severity of the effects of HSP varies from patient to patient. Where one patient may experience early onset HSP, but manage to walk unaided for the rest of their life, another patient may require the use of a wheelchair within a few years of onset.

Whilst there is no cure for HSP, there are a range of treatments which many patients find beneficial. Further reading via our Links page...
