Do infantile spasms always show up on EEG?

Unfortunately, just because a child is having infantile spasms and has an EEG, it doesn't always show up right away. We always talk to families about the importance of requesting a longer EEG to make sure that you're capturing that brain activity for as long as you can to see if hypsarrhythmia is present.

Does an EEG show infantile spasms?

Doctors often confirm the diagnosis of infantile spasms with an electroencephalogram (EEG) test. An EEG shows a specific type of abnormal chaotic brainwave pattern called hypsarrhythmia.

How do you rule out infantile spasms?

To diagnose infantile spasms, your child's doctor will complete a physical and neurologic exam. Your baby will also need a test called an electroencephalogram (EEG), which looks at electrical activity in the brain. Babies who have infantile spasms often have a unique EEG pattern called hypsarrhythmia.

Can infantile spasms go undiagnosed?

Researchers surveyed the parents of 100 children who suffered from infantile spasms and found only 29 were seen by a healthcare provider who accurately diagnosed them within one week of spasm onset. Nearly half waited a month or longer for an accurate diagnosis. Several infants were not diagnosed for years.

What can mimic infantile spasms?

Non-epileptic phenomenon can mimic infantile spasms. Benign neonatal sleep myoclonus refers to abnormal jerky movements, that generally occurs in the first month of life, only during sleep.

Hypsarrhythmia - What Is It? What Does It Mean? - Infantile Spasms

Do infantile spasms happen every day?

Very occasionally, only one spasm will occur at a time. In between clusters of spasms many hours without spasms can occur. Occasionally more than a day will pass without a cluster of spasms. Clusters of spasms often occur after waking from sleep, whatever time of the day.

What times of day do infantile spasms occur?

Though there is almost always a cluster of spasms in the morning when the child awakens from sleep, infantile spasms can occur at any time during the day or night.

When are infantile spasms diagnosed?

What are infantile spasms? Infantile spasms, first described with a group of symptoms known as West syndrome, is a form of epilepsy ​that occurs in 1 in 2,000 children. It typically begins between 2-12 months of age and peaks between 4-8 months of age.

Do babies with infantile spasms sleep more?

It is common for babies who have infantile spasms to become irritable and to go off their feeds. Their sleep pattern also changes in that they may sleep more during the day and less during the night.

What does mild cerebral palsy look like?

However, it is essential to know what the signs of mild CP look like in order to prevent complications from progressing. Signs of mild cerebral palsy include: Abnormal walking: walking on the toes, walking on the heels, continuous bending of the knees, walking with toes pointing inwards or outward, slight limping, etc.

Can MRI detect infantile spasms?

Despite the heterogeneous nature of causes of infantile spasms, a careful diagnostic evaluation can lead to diagnosis in many patients and may guide treatment choices. Magnetic resonance imaging (MRI) brain remains the highest yield initial study in determining the etiology in infantile spasms.

Can reflux look like infantile spasms?

What does a spasm look like? Infantile spasms often has a very subtle appearance that makes it difficult to identify as a serious problem. The spasms can look similar to common disorders such as colic or reflux, or a baby's normal 'startle' reflex.

Do babies make noise during infantile spasms?

While infantile spasms can look similar to a normal startle reflex in babies, there are ways to help tell the difference: Frequency: Loud noises, bright light or sudden movement can trigger a baby to startle. But unlike that single startle reflex, infantile spasms typically happen back-to-back, or in clusters.

What do infantile spasms look like on EEG?

An EEG (electroencephalogram) looks at the electrical activity of the brain. An EEG in a baby with infantile spasms usually shows a pattern called hypsarrhythmia (HIP-sa-RITH-me-ah) when the seizures are not occurring. This high-voltage spike and wave pattern is often helpful in confirming the diagnosis.

What does an absence seizure look like on an EEG?

In the case of childhood absence seizures, EEG shows bilaterally synchronous and symmetrical 3-Hertz spike-and-wave discharges that start and end abruptly. These discharges can sometimes have maximum frontal amplitude or begin with unilateral focal spikes[2].

How long is a EEG for infantile spasms?

Infantile spasms is diagnosed with a test called video-electroencephalography (video-EEG). This involves recording video of a child and monitoring their brainwaves. Brainwaves are monitored using about 20 painless electrodes glued to the scalp. A video-EEG test usually lasts between several hours and 24 hours.

What do Infantile seizures look like?

More pronounced signs may include the baby's arms coming up with a slight head nod and their eyes rolling up. While this type of movement may look like the baby is just startled, spasms may occur for five to ten seconds in a cluster for several minutes when the baby first wakes up or is going to sleep.

When should I worry about muscle twitching?

If muscle twitching is new and you're experiencing additional symptoms, however, Dr. Ondo says this is when muscle twitching becomes more concerning. "We start to worry about fasciculations when they're of relatively sudden onset and there's accompanying weakness, loss of tone and shrinkage in the muscle," says Dr.

Is it normal for babies to have jerky movements?

As a new parent, it's easy to get worried when you see your newborn's odd shaky movements, from quivering chins to trembling hands and jitters to jerky arm and leg gestures. In most cases, these extra movements are completely normal and harmless, and, in most cases, your baby will outgrow them.

How long can infantile spasms go untreated?

Yes, infantile spasms usually stop before 2 to 4 years of age. But according to the National Institute of Neurological Disorders and Stroke, most children with infantile spasms will develop other types of seizures.

Can you interrupt an infantile spasm?

There is no treatment to stop a cluster of infantile spasms after it has started. During a cluster, you can hold your baby or place them on a soft surface (Picture 1). Also, if possible, you should: Take a video of the cluster for the doctor to see.

What do fetal seizures feel like?

The movements are NOT hiccups, it is not the same feeling at all. It feels like a frantic, shaking kind of feeling, usually lasting a few seconds and returning every 5 minutes or so for around 30 minutes.

Does my baby have neurological problems?

Warning signs of a neurological disorder include:

Abnormal muscle tone at birth. Seizures. Floppy baby. Subtle staring/unresponsive episodes.

Do infantile spasms hurt?

They may have many series of spasms per day. This type of seizure is usually only seen in young children. After a spasm, the baby may cry or laugh. The spasms do not cause pain, but the baby may cry because the quick jerking movement surprises them.

What does a seizure look like in a 7 month old?

Focal seizures: Focal seizures may involve the infant having spasms or rigidity in one muscle group, becoming pale, sweating, vomiting, screaming, crying, gagging, smacking their lips, or becoming unconscious.
