Understanding Infant Strokes: Can Babies Have Strokes?

Strokes in babies, known as paediatric strokes, are rare but life-threatening. They occur when there is a blockage or breakage of a blood vessel in the brain, resulting in a loss of blood flow. Perinatal strokes, which can occur anytime from the middle of pregnancy to the first month of a newborn's life, are the most common type of paediatric stroke. They can be caused by various factors, including congenital heart disease, infections, blood clotting disorders, and placental disorders. Recognising the signs of a stroke in a baby can be challenging, but early symptoms may include seizures, twitching, jerking movements, and pausing of breath. If you suspect your child is having a stroke, immediate medical attention is crucial, and long-term follow-up care is essential for optimising recovery.

Perinatal strokes can occur in the womb or after birth

Perinatal strokes, which occur in the womb or after birth, can have serious consequences for newborns. A stroke happens when there is a blockage or breakage of a blood vessel in the brain, resulting in a loss of blood flow to the brain. This, in turn, causes brain cells to die, leading to brain damage and permanent neurological impairment.

Perinatal strokes are a leading cause of brain damage that can result in cerebral palsy. They can occur anytime between the middle of pregnancy, around 22 weeks, and the first month of a newborn's life. They may affect an artery or a vein, and symptoms may appear right at birth or later, sometimes years later.

The most common type of perinatal stroke is an ischemic stroke, which is caused by a blockage in the blood vessel. Hemorrhagic strokes, on the other hand, are caused by breakage in the blood vessel. Perinatal strokes can be challenging to diagnose, and many children may not exhibit typical stroke symptoms. Seizures are the most common symptom in infants, and other symptoms such as numbness, weakness, or paralysis on one side of the body may appear as the child ages.

Certain risk factors have been identified for perinatal strokes, including congenital heart disease, infections, blood clotting disorders, and placental disorders. Birth trauma, such as asphyxiation, may also contribute to perinatal strokes. When a perinatal stroke is suspected, diagnostic tests such as imaging scans (CT, MRI, or ultrasound) can be performed to confirm the diagnosis.

Treatment for perinatal strokes varies depending on the type of stroke and the complications it has caused. Anticonvulsant medications may be used to limit or stop seizures, and surgery may be necessary to remove pooled blood and relieve pressure on the brain in cases of hemorrhagic stroke. Therapeutic hypothermia, which involves cooling the infant's head for up to 72 hours, has also emerged as a promising treatment for reducing fatality rates and brain damage.

Ischemic strokes are the most common type of perinatal stroke

Babies can have strokes, and these are known as perinatal strokes. Perinatal strokes occur from 20 weeks' gestation, including in utero, to 28 days postnatally. Ischemic strokes are the most common type of perinatal stroke, and they occur when an artery is blocked by a blood clot. Arteries are the blood vessels that carry blood to the brain, and when blood flow to the brain is blocked or interrupted, brain cells begin to die, and brain damage can occur. This can lead to permanent damage to the brain and cause a person's body to no longer function normally.

Ischemic strokes can be caused by a lack of oxygen during birth, a heart defect present at birth, blood disorders such as sickle cell anemia, injury to an artery in the brain, genetic disorders, or an infection such as meningitis or chickenpox. Certain problems during pregnancy can also increase the risk of ischemic stroke in the baby, including preeclampsia, premature rupture of the membranes, and placenta problems that decrease the baby's oxygen supply.

The signs of a perinatal stroke may be recognized in the first hours or days of life, with seizures being the most common sign. However, a baby may also be lethargic or have breathing problems. In some cases, the signs of a perinatal stroke may not appear until later in infancy, and parents may notice early hand preference or other motor development asymmetries when the baby is about six months old.

While there are no easy ways to open blocked blood vessels in perinatal stroke patients, acute treatment focuses on protecting the freshly injured brain. This includes recognizing and treating seizures, avoiding increased body temperature, optimizing brain blood flow, correcting dehydration, and maintaining normal blood sugar levels.

Strokes in babies can be caused by congenital heart disease

Yes, babies can have strokes. While strokes are less common in children, they do occur in babies, even before they are born. Strokes in babies are called perinatal strokes and usually occur during or right after delivery when the baby doesn't get enough oxygen while traveling through the birth canal.

Strokes happen when blood flow to the brain is blocked or interrupted, either by a blood clot or a broken blood vessel. When this happens, brain cells begin to die, and brain damage can occur. This can cause permanent damage to the brain and affect a person's body functions.

One of the risk factors for stroke in babies is congenital heart disease (CHD). CHD is a structural problem with the heart that is present at birth and can increase the risk of stroke. It occurs when there is a mishap during heart development soon after conception, often before the mother is aware she is pregnant.

CHD can range from simple problems, such as "holes" between chambers of the heart, to severe malformations like the complete absence of one or more chambers or valves. These defects can impair the normal circulation pattern of blood flow and increase the risk of stroke.

Cardiac disorders, including congenital heart disease, are associated with 10% to 30% of strokes in children. Infants with cyanotic CHD, which involves a right-to-left shunt in the heart, are particularly vulnerable to arterial ischemic stroke (AIS) during the periprocedural period after cardiac surgery or catheterization.

In summary, strokes in babies can be caused by congenital heart disease, which is a structural problem with the heart present at birth. CHD can disrupt the normal circulation of blood and increase the risk of stroke, making it an important factor to consider in the context of pediatric stroke.

Prompt treatment can make a big difference in a baby's health and recovery

A stroke is a life-threatening condition that occurs when blood flow to the brain is blocked or interrupted, either by a blood clot or a broken blood vessel. When this happens, brain cells begin to die, and brain damage can occur. While strokes are rare in babies, they do happen and prompt treatment can make a big difference in a baby's health and recovery.

Strokes in babies are often called perinatal strokes and they usually occur between the 28th week of pregnancy and one month after birth. They can be caused by a lack of oxygen during birth, congenital heart defects, blood disorders, or infections. The risk factors for stroke in babies include congenital heart disease, high blood pressure in the mother during pregnancy (preeclampsia), and premature rupture of the membranes.

The signs and symptoms of a stroke in a baby can include seizures in one area of the body, trouble breathing, early preference for using one hand over the other, and developmental delays. If you suspect your baby is having a stroke, it is important to act quickly. Call 911 or your local emergency number and have your baby lie flat. Do not give them anything to eat or drink.

Once your baby is stabilised in the emergency department, the focus will turn to rehabilitation. Starting rehabilitation as soon as possible is vital to your baby's recovery. This might include physical therapy, occupational therapy, and speech-language therapy. The rehabilitation team will work with you to determine the best course of treatment for your baby.

With prompt treatment and rehabilitation, most children who have had a stroke are able to function normally and grow up to be productive members of their communities. However, it is important to remember that each child's recovery is different and some may have permanent changes to their cognitive and physical abilities.

Therapeutic hypothermia is an emerging treatment for strokes in infants

Therapeutic hypothermia can be induced by invasive endovascular means, surface cooling, intravenous infusion of chilled saline, or a combination that targets either systemically cooling the entire body or selectively cooling the brain only with minimal effects on the core temperature. The optimal target temperature and duration of therapeutic hypothermia are still being studied, but temperatures of 34°C or below have been shown to be most effective. The earlier therapeutic hypothermia is induced, the more effective it is, and longer durations of cooling following global cerebral ischemia have been associated with better outcomes.

There are some complications and side effects associated with therapeutic hypothermia, including cardiovascular complications, greater risks of infection, coagulopathies, and electrolyte imbalances. The frequency of these side effects increases with each 1°C decrease in temperature and longer durations of cooling. Gradual rewarming may be safer and preferable in patients with high intracranial pressure or those that have been cooled for a longer duration.
