Life expectancy for West syndrome is variable. About five in every 100 infants and children with West syndrome do not survive beyond five years of age. A study of 214 Finnish children over 25 years of age showed about 61% dying at or before age 10 years.
Treatment of infantile spasms has little class I data, but adrenocorticotropic hormone (ACTH), prednisolone and vigabatrin have the best evidence as first-line medications. Other therapies including the ketogenic diet and other anti-epileptics medications may also prove useful in the treatment of infantile spasms.
In a typical attack of Sandifer syndrome, a baby's back will arch suddenly. With their back flexed, their head and legs also splay out backward. They become stiff. Other expressions of the syndrome include nodding head movements, twisting or tilting of the head, or thrashing limbs.
Infantile spasms is a complex and rare disorder that can have very serious consequences. It can lead to death in some babies, and cause intellectual disabilities and developmental problems in others. Even once the seizures are gone, the damaging brain effects can remain.
Infantile spasms (IS), i.e., West syndrome, as an epileptic encephalopathy, represents one of the major causes of acquired mental retardation in early childhood (Roger and Dulac, 1994).
Symptoms of Infantile Spasms (IS)
- Raise their arms over their head or stick their arms straight out to the side.
- Stiffen their legs or "tuck them into the belly," as if having stomach pain.
- Suddenly bend at the waist.
- Drop or bob their heads briefly.
- Roll their eyes back suddenly with subtle head nodding.
A new study found that nearly half of babies who suffer from infantile spasms are not accurately diagnosed for more than a month and this delay can increase the risk of intellectual disability, autism, lifelong epilepsy, and death.
Infantile spasms (also 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.
Most children of people with epilepsy do not develop seizures or epilepsy. However, since genes are passed down through families, it is possible. Epilepsy is more likely to occur in a brother or sister if the child with epilepsy has generalized seizures.
There may only be a few spasms in a cluster or there may be many, even more than one hundred. 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.
Infantile spasms usually An epileptic spasm is a specific type of seizure seen in an epilepsy syndrome of infancy and childhood often called West Syndrome. These are more commonly called infantile spasms (IS) since they are seen most often in the first year of life.
Others may have been born with a genetic mutation or have problems with brain development. Certain medical and genetic conditions, like Down syndrome, increase the risk of having infantile spasms. In 20 to 30 percent of children with this type of epilepsy, doctors can't find a cause.
Infantile spasms (IS) are a type of seizure that is linked to an epileptic condition known as West syndrome. West syndrome affects infants and children. Infantile spasms are linked to mental delays.
Hypsarrhythmia is the most common interictal EEG pattern associated with infantile spasms. The most common clinical description is a sudden, symmetric, tonic muscle contraction producing flexion/extension of the trunk and extremities, although a variety of movement patterns have been described.
Each spasm usually lasts less than 10 seconds. A cluster or severe spasms can last for minutes. 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.
Lennox-Gastaut syndrome can have many different causes. The disorder likely has a genetic component, although the specific genetic factors are not well understood. Most cases of Lennox-Gastaut syndrome are caused by an existing neurological abnormality.
Myoclonic astatic epilepsy (MAE), also known as Doose syndrome, is an epilepsy syndrome of early childhood, most commonly appearing between ages 1 and 5 and featuring generalized seizures. Children will experience drop attacks and staring seizures, sometimes associated with falls.
The spasms are brief, often lasting one or two seconds. They tend to occur in clusters where the infant may have several spasms over a few minutes. Spasms often occur when the infant is falling asleep or waking up from sleep. They rarely occur during sleep.
Expect some of the following: Sudden jerks or twitches of the arms, hands or legs. If they only occur during sleep, they are most likely normal. How Long: last a few seconds, but can recur.
The sooner your little one starts treatment for infantile spasms or West syndrome, the better, because this condition can affect how their mind and body develop. In some cases, the seizures and spasms will stop on their own, but most children will need treatment.
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. For an example of how a focal seizure might look, click here.
UI researchers believe that infants' twitches during rapid eye movement (REM) sleep are linked to sensorimotor development—that when the sleeping body twitches, it's activating circuits throughout the developing brain and teaching newborns about their limbs and what they can do with them.
