Insights

In children with acute arterial ischemic stroke (AIS), 22% presented with seizures, particularly younger children. Seizures at presentation were linked to focal neurological deficits but not stroke cause or location.

Area of Science:

  • Pediatric Neurology
  • Neuroscience
  • Stroke Research

Background:

  • Acute arterial ischemic stroke (AIS) in children is a significant cause of neurological disability.
  • Seizures are a known complication of stroke, but their incidence and associated risk factors in pediatric AIS require further definition.

Purpose of the Study:

  • To determine the incidence of seizures as a presenting symptom in pediatric AIS.
  • To identify risk factors, including age, infarct location, and etiology, associated with seizures at AIS presentation.

Main Methods:

  • A prospective pediatric stroke registry was utilized to identify children aged 2 months to 18 years with AIS.
  • Clinical data and imaging studies were reviewed to assess seizure occurrence and related factors.

Main Results:

  • Of 60 children with AIS, 13 (22%) experienced seizures at presentation.
  • Younger age was a significant risk factor for seizures (median age 1.1 years vs. 10 years).
  • All seizure patients had hemiparesis; 3 of 4 with overt seizures also had nonconvulsive seizures.

Conclusions:

  • Seizures are a common presenting symptom in pediatric AIS, occurring in 22% of cases.
  • Younger age is a key risk factor for seizures at AIS presentation.
  • Nonconvulsive seizures may be present during the acute phase of pediatric AIS.

Seizures l: Introduction

Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Ischemic Stroke l: Introduction01:15

Ischemic Stroke l: Introduction

Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Seizures ll: Types

Seizures are sudden bursts of abnormal electrical discharge in the brain that interfere with normal function. They are commonly divided into three groups: focal seizures, generalized seizures, and other types that do not fit neatly into either category.Focal SeizuresFocal seizures begin in a single brain region. When awareness is preserved, they are called focal aware seizures and may cause sensations such as tingling, unusual smells, or flashing lights. When awareness is impaired, they are...

Epilepsy ll: Types

Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.
Stroke: Introduction and Types01:29

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
