Living with Hereditary spastic paraplegia 11

A type of hereditary spastic paraplegia with worsening leg stiffness and other nervous system symptoms.

Understanding Hereditary spastic paraplegia 11

Hereditary spastic paraplegia 11 (SPG11) is a form of hereditary spastic paraplegia with worsening muscle stiffness in the legs.

Stiffness leads over time to paralysis of the legs. Other nervous system symptoms can include intellectual disability, speech trouble (dysarthria), and reduced bladder control. The corpus callosum, the tissue connecting the two halves of the brain, is abnormally thin in most people. It can start at a variety of ages.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Stiff, weak legs
  • Trouble walking
  • Poor balance (ataxia)
  • Speech trouble (dysarthria)
  • Mild intellectual disability
  • Memory changes

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

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in SPG11 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Spastic Paraplegia Foundation may keep lists of experts for this condition.
