Understanding Mini Strokes In Toddlers: What Parents Should Know

can I toddler have a mini stroke

Strokes are rare in toddlers, but they can happen. A stroke occurs when blood flow to the brain is blocked or interrupted, either by a blood clot or a broken blood vessel. When either of these things happens, brain cells can die, and brain damage can occur. This can cause permanent damage to the brain and affect how the body works. It can also change how a person thinks and feels.

Can toddlers have strokes?

Strokes in toddlers are rare but they do happen. A stroke occurs when blood flow to the brain is blocked or interrupted, either by a blood clot or a broken blood vessel. When either of these things happen, brain cells begin to die and brain damage can occur.

Strokes in children most often happen within the first month after birth, known as perinatal strokes. These strokes happen during delivery or right after when the baby doesn't get enough oxygen while traveling through the birth canal.

Strokes can also affect older children. However, most of these are caused by another condition that stops the flow of blood to the brain or causes bleeding in the brain.

The risk factors for stroke in children are varied and include:

  • Lack of oxygen during birth
  • A heart defect the baby is born with
  • Blood disorders such as sickle cell disease, which destroys blood cells and blocks blood vessels
  • Injury to an artery (a blood vessel that brings oxygen) in the brain
  • Genetic disorders like Moyamoya, a rare disease that affects arteries in the brain
  • An infection, such as meningitis or chickenpox

The signs of a stroke in a toddler may include:

  • Weakness or numbness in the face, arm or leg, especially on one side
  • Difficulty speaking, understanding, reading or writing
  • Trouble seeing or loss of vision
  • Dizziness, loss of balance or poor coordination
  • Severe or unusual headaches, nausea or vomiting
  • Difficulty swallowing, including drooling
  • Seizures with weakness that doesn’t improve
  • Changes in behaviour and difficulty concentrating

If you notice any of these signs, call emergency services immediately. Even if you aren’t sure, or the signs only last for a few minutes, seek emergency medical help.

What are the signs of a stroke in a toddler?

Strokes in toddlers are rare but can happen. A stroke occurs when there is a blockage in the blood supply to the brain, resulting in brain cells dying due to a lack of oxygen. This can lead to permanent brain damage and affect how the body functions.

  • Weakness or numbness in the face, arm, or leg, especially on one side of the body.
  • Difficulty speaking, understanding, reading, or writing.
  • Trouble seeing or loss of vision.
  • Dizziness, loss of balance, or poor coordination.
  • Severe or unusual headaches, nausea, or vomiting.
  • Difficulty swallowing, including drooling.
  • Seizures with weakness that doesn't improve.
  • Changes in behaviour and difficulty concentrating.
  • Paralysis or weakness on one side of the body.
  • Language or speech delays or changes, such as slurring.
  • Vision problems, such as blurred or double vision.
  • Tendency to not use one of the arms or hands.
  • Tightness or restricted movement in the arms and legs.

If you notice any of these signs in a toddler, it is crucial to seek immediate medical attention by calling an emergency number. Prompt diagnosis and treatment can minimize the risk of lasting problems, and early rehabilitation can help maximize recovery.

What should you do if you think a toddler is having a stroke?

Strokes are rare in toddlers, but they can happen. If you think a toddler is having a stroke, it is important to act quickly and seek emergency medical attention. Here is what you should do:

Recognise the Signs and Symptoms

Firstly, it is important to recognise the signs and symptoms of a stroke in a toddler. These can include:

  • Changes in behaviour or thinking
  • Changes in hearing or vision
  • Clumsiness or difficulty with coordination
  • Difficulty swallowing
  • Muscle weakness or paralysis on one side of the body
  • Trouble speaking or understanding words
  • Seizures
  • Headaches, possibly with vomiting
  • Tendency to favour one hand over the other
  • Developmental delays

Call for Emergency Medical Help

If you notice any of these symptoms, call for emergency medical help immediately. In the US, call 911. In the UK, call 999. It is important to act quickly, as prompt treatment can make a big difference in the child's health and recovery.

Provide Information to Medical Professionals

When the emergency services arrive, provide them with as much information as possible about the toddler's condition and any symptoms you have observed. This will help them make an accurate diagnosis and provide the best possible care.

Seek Specialist Care

If a stroke is suspected, the toddler will likely be referred to a specialist for further evaluation and treatment. This may include various tests, such as MRI scans, CT scans, and blood tests, to determine the type and cause of the stroke.

Begin Rehabilitation

After the initial emergency treatment, the toddler will likely need rehabilitation to aid their recovery. This may involve working with a team of specialists, including paediatric neurologists, cardiologists, and occupational therapists, to help the child regain any lost functions and learn to adapt to any lasting effects of the stroke.

What are the different types of stroke?

While toddlers can have strokes, let's take a look at the different types of strokes that can occur.

There are several types of strokes, and doctors can classify them in various ways, including by their location or by the blood vessels involved. However, the three main types of strokes are:

  • Transient ischemic attack (TIA), also known as a mini-stroke, is a temporary blockage of blood flow to the brain. The symptoms are similar to an ischemic stroke but usually last a few minutes to a few hours and fully resolve within 24 hours.
  • Ischemic stroke occurs when a blood vessel supplying blood to the brain is blocked by a blood clot. This is the most common type of stroke, accounting for 87% of all strokes.
  • Hemorrhagic stroke happens when a weakened blood vessel in the brain ruptures or breaks, flooding the brain with blood. The two types of weakened blood vessels that usually cause hemorrhagic strokes are aneurysms and arteriovenous malformations (AVMs).

Ischemic Strokes: Thrombotic vs. Embolic

Ischemic strokes can be classified into two main types:

  • Thrombotic strokes are caused by a blood clot that forms in an artery supplying blood to the brain.
  • Embolic strokes occur when a clot forms elsewhere in the body and travels through the blood vessels to the brain, blocking blood flow.

Ischemic Strokes: Lacunar vs. LVO

Ischemic strokes can also be classified based on the size and location of the blood vessels involved:

  • Lacunar strokes affect small blood vessels deep within the brain and usually result from atherosclerosis. They account for 15-25% of ischemic strokes and can often go unnoticed without symptoms.
  • Large vessel occlusion (LVO) strokes affect larger arteries within the brain and are more severe than lacunar strokes, making up 24-46% of ischemic strokes.

Hemorrhagic Strokes: ICH vs. SAH

Hemorrhagic strokes can be classified based on where the rupture occurs:

  • Intracerebral hemorrhage (ICH) occurs when a blood vessel in the brain bursts, accounting for about three-quarters of hemorrhagic strokes.
  • Subarachnoid hemorrhage (SAH) involves the rupture of a blood vessel in the subarachnoid space, a layer surrounding the brain.

What are the risk factors for a toddler having a stroke?

While strokes are rare in toddlers, they can still occur. The risk of stroke is highest before the age of one, and it is one of the top 10 causes of death in children.

Some conditions can put toddlers at an increased risk of stroke. Here are the risk factors:

Heart Problems

The most common cause of strokes in toddlers is heart problems, particularly congenital heart defects or disorders. These issues can impact blood flow and oxygen supply to the brain, increasing the risk of a stroke.

Sickle Cell Disease

Sickle cell disease is a blood disorder that can increase the risk of blood clots or brain bleeds, leading to a stroke. This disease is a common risk factor for strokes in children.

Infections

Infections such as meningitis or encephalitis can elevate the risk of stroke in toddlers. These infections can affect the brain and disrupt normal blood flow, making them a critical risk factor.

Metabolic Disorders

Certain metabolic disorders can also put toddlers at risk of stroke. These disorders can impact the body's ability to regulate blood flow and oxygen supply to the brain, increasing the likelihood of a stroke.

Blood Clotting Problems

Toddlers with blood clotting problems are at a higher risk of stroke. This is because effective blood flow is crucial for oxygen supply to the brain, and blood clots can obstruct this flow.

Blood Vessel Abnormalities

Abnormalities in blood vessels, such as dissection or vasculitis, can increase the risk of stroke in toddlers. These abnormalities can affect blood flow and make it more difficult for oxygen-rich blood to reach the brain.

Traumatic Brain Injury (TBI) or Neck Injury

Traumatic brain injuries and neck injuries are risk factors for stroke in toddlers. These injuries can affect the brain's blood vessels and impact normal blood flow, increasing the likelihood of a stroke.

High Blood Pressure (Hypertension)

Hypertension, or high blood pressure, is a risk factor for stroke in toddlers. It can impact the flow of oxygen-rich blood to the brain, making it an important consideration in stroke risk assessment.

Genetic Syndromes

Certain genetic syndromes, such as Down syndrome, can increase the risk of stroke in toddlers. These syndromes can affect blood vessels and blood flow to the brain, making them a critical factor in stroke risk assessment.

Cerebral Hypoxia during Birth

Cerebral hypoxia, or a lack of oxygen to the brain during birth, is a risk factor for stroke in toddlers. This condition can cause brain damage and increase the likelihood of a stroke later in life.

Thrombophilia or Hemophilia

Thrombophilia and hemophilia are blood disorders that can increase the risk of blood clots. As a result, they are considered risk factors for stroke in toddlers, as blood clots can obstruct blood flow to the brain.

It is important to note that in many cases of pediatric stroke, no specific cause can be identified. Additionally, the risk factors mentioned above do not guarantee that a stroke will occur, but they do indicate an increased likelihood. If you suspect that a toddler is exhibiting stroke-like symptoms, it is crucial to seek immediate medical attention.

Frequently asked questions

Yes, toddlers can have what is known as a transient ischaemic attack (TIA) or mini-stroke. During a TIA, a blood vessel in the brain gets blocked, but the blockage clears by itself. While the symptoms of a TIA last for a short amount of time, it is still a major warning sign of a potential stroke and should be treated as a medical emergency.

Signs of a mini stroke in a toddler include:

- Sudden, severe headache

- New and sudden vertigo, dizziness, or confusion

- Problems with walking or balance

- Nausea/vomiting, drowsiness, or loss of consciousness

- Sudden blurred vision or loss of sight in both eyes

- Weakness or numbness on one side of the body

- Changes in sensation, like pins and needles in arms or legs

If you suspect your toddler is having a mini stroke, call 911 or your local emergency number immediately. Do not give your child anything to eat or drink, and have them lie flat while waiting for emergency responders to arrive.
