Bringing Awareness to Alternating Hemiplegia of Childhood 

January has been designated as a time to bring awareness to alternating hemiplegia of childhood!

Alternating hemiplegia of childhood is extremely rare, with about 1 in 1,000,000 reported cases; therefore it’s important to shine a spotlight during its awareness month.

Let’s take a deeper dive!

What is AHC?

Alternating Hemiplegia of Childhood is a rare neurological disorder that develops in childhood, most often before the child is 18-months old.

The disorder is characterized by recurrent episodes of paralysis that involve one or both sides of the body, multiple limbs, or a single limb. The paralysis may affect different parts of the body at different times and may be brief or last for several days. Oftentimes these episodes will resolve after sleep. 

There are both benign and more serious forms of the disorder.

What are Symptoms of AHC?

Children with alternating hemiplegia exhibit a wide range of symptoms. These include:

  • Tonic attacks (lack of muscle tone)
  • Dystonic posturing (stiffening of extremities)
  • Ataxia (lack of coordination when performing voluntary movements)
  • Nystagmus (fast uncontrollable movements of the eyes that may be side to side, up and down, or rotary)
  • Ocular motor abnormalities (eye disorders)
  • Developmental delays
  • Seizures 

Up to 50% of children with AHC develop “true seizures” sometime during the course of their illness.
