Living with Spastic quadriplegic cerebral palsy

An inherited form of cerebral palsy with stiff muscles in all four limbs from early life.

Understanding Spastic quadriplegic cerebral palsy

Spastic quadriplegic cerebral palsy, also called inherited congenital spastic tetraplegia, is a rare genetic neurological disease.

It causes stiff muscles (spasticity) in all four limbs that does not worsen over time. It occurs in several family members without birth complications such as lack of oxygen or infection. Other features include low muscle tone at birth, intellectual disability and developmental delay. Trouble swallowing and speaking, eye differences and seizures can also occur. It starts in the newborn and infant period.

Signs & symptoms

GARD doesn't list a separate symptom list for this condition. Based on its summary, features include:

  • Stiff muscles in all four limbs
  • Low muscle tone at birth

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
