In what age does West syndrome start?

Symptoms associated with West syndrome usually begin during the first year of life. The average age of onset for epileptic spasms is at 6 months. Epileptic spasms are characterized by involuntary muscle spasms that occur due to episodes of uncontrolled electrical disturbances in the brain (seizures).

Can you grow out of West syndrome?

It's rare, but some children who had West syndrome as babies will die before adulthood. It usually happens before the age of 10. Your baby is more likely to develop normally if: They were at least 4 months old before they got West syndrome.

How do you get West syndrome?

Sometimes West syndrome is caused by an injury to the brain. Other times, it is caused by developmental anomalies of brain structure. West syndrome can also be caused by genetic mutations or metabolic disorders. In some cases, no cause can be found.

How common is West syndrome?

The combination of the infantile spasms, age of onset and EEG pattern defines the epilepsy syndrome called, 'West syndrome'. It is called this after Dr William West, who first described the condition in his 4-month-old son in 1841. West syndrome happens in about one in 2,500-3,000 children.

What age do infantile spasms start?

Most infants with infantile spasms develop a pattern of movements called spasms, sometimes also referred to as epileptic spasms. The most common age for these spasms to begin is between 3 and 6 months of age. They can begin earlier than 3 months and sometimes begin after 12 months of age.

Signs of Infantile Spasms

How do I know if my baby has infantile spasms?

During an infantile spasm, your baby's body will stiffen or tense up suddenly and only for a couple of seconds. They may also arch their back, and their arms, legs and/or head may bend forward. Infantile spasms often happen one after another in a cluster with five- to 10-second pauses in between spasms.

Why does my 3 month old leg shake?

Moving their arms and legs all around can be one of the signs that your baby is hungry. Crying, which can also create shaking, trembling, or stiffening of the body, is also a late sign of hunger. Low blood sugar can also cause shivering in babies.

How do you know if you have West syndrome?

Signs & Symptoms

Symptoms associated with West syndrome usually begin during the first year of life. The average age of onset for epileptic spasms is at 6 months. Epileptic spasms are characterized by involuntary muscle spasms that occur due to episodes of uncontrolled electrical disturbances in the brain (seizures).

Can a 1 month old have infantile spasms?

Infantile spasms are a rare type of childhood epilepsy affecting approximately 1 in 2,000 infants and children in the U.S. each year. The spasms are tiny seizures that can have a big impact on a baby's development. Infantile spasms most often begin when a baby is 3 to 12 months old.

How do you prevent infantile spasms?

Infantile spasms usually are treated with seizure medicines or steroids. If medicines don't control the spasms, a special diet, such as the ketogenic diet, might help. Sometimes, doctors may recommend surgery.

When do infantile spasms stop?

Infantile spasms usually stop by age five, but may be replaced by other seizure types. Many underlying disorders, such as birth injury, metabolic disorders, and genetic disorders can give rise to IS, making it important to identify the underlying cause. In some children, no cause can be found.

Is West syndrome caused by vaccines?

In addition, decades of epidemiological research into the issue presented in this case—whether pertussis vaccination causes West Syndrome—has not yielded reliable evidence of a causal link.

What is the difference between West syndrome and infantile spasms?

(See Presentation and Workup.) West syndrome is an age-dependent expression of a damaged brain, and most patients with infantile spasms have some degree of developmental delay. The term infantile spasm has been used to describe the seizure type, the epilepsy syndrome, or both.

Can babies with West syndrome live a normal life?

West syndrome is generally not life-threatening but it occurs more often in children with life-threatening conditions. Furthermore, the treatments used for West syndrome can (rarely) cause death. As a result, only 5 out of every 100 children diagnosed with West syndrome will not survive beyond the age of five years.

Do infantile spasms happen in sleep?

Infantile spasms often occur when a child is falling asleep or waking up. The child's body may suddenly jerk, flex or extend. Sometimes, the arms are flung out, the knees are pulled up and the body bends forward.

Why is my newborn jumping in his sleep?

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.

Why does my baby violently shake his head?

Summary. As babies discover the world, they continually develop new skills. Sometimes, unusual behaviors appear along with these skills. In most cases, head shaking is a normal, developmentally appropriate behavior that shows that a baby is exploring and interacting with their world.

Why do babies legs shiver?

A still-developing neurological system also sends more electrical impulses to muscles than necessary, which can cause your baby's chin to quiver or legs to tremble. As things become more organized over the first couple of weeks, she'll tend to shake less.

When do newborns stop sneezing?

Newborn Sneezing and the Flu

This respiratory illness can cause some sneezing, although not typically as much as the common cold. The flu tends to feel worse than a cold, but healthy babies, children, and adults may start to feel better after just one or two weeks.

What age do babies roll over?

Babies start rolling over as early as 4 months old. They will rock from side to side, a motion that is the foundation for rolling over. They may also roll over from tummy to back. At 6 months old, babies will typically roll over in both directions.

Can bouncing a baby cause shaken baby syndrome?

Shaken baby syndrome does not result from gentle bouncing, playful swinging or tossing the child in the air, or jogging with the child. It also is very unlikely to occur from accidents such as falling off chairs or down stairs, or accidentally being dropped from a caregiver's arms.

Why do 2 month olds shake legs?

Jitters or trembling of the arms and legs during crying is normal in newborns. It should stop by 1 to 2 months of age. If your baby is jittery when not crying, it could be abnormal. Give her something to suck on.

Why do babies jerk their arms and legs?

Newborns have an immature nervous system. The pathways that carry the signals from the brain to the parts of the body aren't yet fully developed, so their movements can appear jerky and twitchy.

Why is my toddler twitching?

Toddlers twitching in their sleep is pretty common, and it's believed that the twitching may be linked to sensorimotor development in babies and toddlers. The body's twitching while asleep could be the brain's way of teaching your child about their limbs and what they can do with them!

Why does my baby randomly jerk?

Generally, these twitches are perfectly normal. In fact, some researchers now believe that these myoclonic twitches help babies transform their rudimentary movements into coordinated movements. There are two types of sleep twitches: Myoclonic twitches caused by sudden muscle contractions.
