Infancy and Newborn Period Syndromes

Epilepsies that appear in the first months and first year of life require special attention. In this period, early diagnosis and prompt treatment can be extremely valuable for a child's development. Although some of the conditions in this chapter have a severe course, remember the power of knowledge: the earlier they are recognized, the better they can be managed.

Infantile Epileptic Spasms Syndrome (West Syndrome)

This syndrome is classically known as "West syndrome" and usually begins in the first year of life, most often between the 3rd and 8th months. It has three main features: infantile spasms (brief, sudden contractions), a very abnormal pattern on the EEG called hypsarrhythmia, and often a halt or regression in development.

How Do the Spasms Look?

Infantile spasms are very brief and easily misunderstood. The baby suddenly drops their head forward, flings their arms up or forward, and tenses the torso — as if startled. These spasms come not one at a time, but in back-to-back series; especially after waking from sleep. Families often mistake this for "stomach pain," "colic," or a "startle." This is exactly why recognizing this sign is vitally important.

If You See This, Do Not Lose Time

If you notice, especially after waking, back-to-back series of brief contractions in your baby in the form of throwing the head forward and flinging the arms, record it on video if you can and see a pediatric neurologist without delay.

In West syndrome, early treatment can positively affect the developmental course. Time truly matters here.

Treatment

The treatment of infantile spasms usually involves special hormonal treatments (ACTH or high-dose corticosteroids) and, in certain situations (for example, on a background of tuberous sclerosis), medications such as vigabatrin. These treatments must always be carried out at an experienced center and under close follow-up. The aim of treatment is both to stop the spasms and to correct the abnormal EEG pattern.

Dravet Syndrome

Dravet syndrome is a rare but severe, genetically based developmental and epileptic encephalopathy. It usually begins in the first year of life, in a baby who has developed healthily until then, often with prolonged seizures triggered by fever. Over time, different seizure types are added, the seizures become resistant to medication, and a slowing in development is seen.

Behind the great majority of Dravet syndrome cases lies a change in a specific gene (SCN1A) that affects the sodium channels in the brain. This information is critical for treatment: some common epilepsy medications that block the sodium channel markedly worsen seizures in Dravet syndrome, and so there are medications that must be avoided in these children. The correct diagnosis makes it possible to avoid the wrong medication. Today, new treatments specifically approved for Dravet syndrome (for example, certain new molecules and cannabidiol) offer hope.

Other Early-Onset Epileptic Encephalopathies

There are also severe epilepsy conditions that begin in the first days or weeks of life, often due to genetic or structural-metabolic causes. In these conditions, genetic tests and metabolic investigations are especially important, because some rare conditions (for example, certain vitamin-dependent seizures) can improve dramatically with directly targeted treatments. For this reason, early and detailed investigation can make a big difference in these babies.

To the Family of a Child With a Severe Syndrome

Some of the syndromes you have read about in this chapter are challenging conditions with developmental effects. If your child is in this group, we want you to know that this is a road that requires patience and support, but one you will not have to walk alone. These children benefit most from a many-sided approach that, along with seizure control, includes developmental support, physiotherapy, speech and language therapy, and special education. The aim is not only to reduce seizures but to bring out the child's fullest potential in every area.

In these kinds of syndromes, every child's course is different, and generalizations do not always hold. Some children progress far better than expected. Noticing and celebrating small gains (a new word, a new skill, fewer seizures) gives strength to both the child and you. Building a support network on this journey (family associations, other families in a similar situation, specialist teams) lightens the load and reminds you that you are not alone.

The Importance of Early Intervention

In epilepsies that begin in the first years of life, early diagnosis and early intervention can make a big difference. The reason is that a child's brain is going through the period when it develops fastest and is most flexible. Bringing seizures under control early and starting developmental support early can positively affect the child's long-term course. So if you notice unusual movements or a halt in development in your infant, the best thing to do is to see a pediatric neurologist without waiting.
