Getting an IS diagnosis

After you've noticed the symptoms of infantile spasms (IS), your first step will likely be to visit your child's pediatrician or the emergency room. When you speak with office staff or the doctor, tell them you suspect your baby has infantile spasms.

Be prepared to show your doctor a video of your baby's movements that made you suspect IS. Talk to your doctor and ask questions. The doctor may initially think of colic, gastroesophageal reflux disease (GERD), or another condition, so you will need to be specific about what you're seeing and why it concerns you.

Why see a specialist?

When you tell the doctor what you've seen and that you suspect IS, he or she is likely to refer you to a pediatric neurologist. Infantile spasms is so rare and so complicated that it is generally only treated by a doctor with special training in both neurology (treating the brain) and pediatrics.

These doctors are often affiliated with large medical centers, so you may have to travel some distance on short notice to meet with them. Here, too, tell the office staff and the doctor that you suspect your baby has IS. The neurologist will also want to see the video of your baby's movements.

The doctor's diagnosis

In addition to the video of your baby's spasms, the neurologist may take a full medical history of your child, including when the spasms happen, how long they've been happening, and how long they last. The neurologist may also measure and ask about any delayed development your child may have experienced. As soon as you suspect IS, you may wish to start tracking all of this information to share with doctors.

Then, the doctor may order an electroencephalogram (EEG). This is a noninvasive, painless test that measures brain-wave patterns. Children with IS show a distinctive, unusual pattern called hypsarrhythmia.

With the medical history and EEG, the neurologist may be able to diagnose IS, if that's what's happening. Together you can begin to discuss a plan for treatment.
