What is West Syndrome (Infantile Spasm)?

A type of epilepsy (recurrent seizures) that occurs in young children. These are more commonly called infantile spasms (IS) because they are seen most often in the first year of life, typically between ages 4 and 8 months. They often look like a sudden bending forward of the body with stiffening of the arms and legs lasting for one to two seconds; some children arch their backs as they extend their arms and legs. Spasms tend to happen when the infant wakes up, and often happen in many clusters, with hundreds of seizures per day. It results from damage to the developing brain, with various causes like chromosomal abnormalities (e.g. Down's syndrome), brain malformations, or brain infections.

Typical Symptoms of West Syndrome (Infantile Spasm)

  • Seizure

  • Losing consciousness

  • Repetitive movements e.g. head-shaking, nodding

  • Seizure shortly after waking up

  • History of epilepsy

  • Child is developing slower than his or her peers

  • Weakness in arms or legs

  • Spontaneous clonic muscle contractions

Doctor's Diagnostic Questionson West Syndrome (Infantile Spasm)

Your doctor may ask these questions to check for this disease:

  • Have you had a seizure?

  • Have you temporarily lost consciousness?

  • Do you have repetitive head movements such as shaking or nodding?

  • Did you have a seizure after waking up?

  • Have you ever been diagnosed with epilepsy?

Treatmentof West Syndrome (Infantile Spasm)

Many underlying disorders, such as birth injury, metabolic disorders, and genetic disorders can give rise to IS, making it important to identify the underlying cause. In some children, no cause can be found. Treatment aims to reduce seizure frequency. Options for treatment include hormone therapy, a ketogenic diet, and anti-seizure medications.
