Insights
Pediatric brain attacks present differently than in adults, with stroke being less common. Understanding these unique symptoms and causes is key to developing effective emergency department care pathways for children.
Area of Science:
- Pediatric Neurology
- Emergency Medicine
- Clinical Pathway Development
Background:
- Brain attacks in children, defined as abrupt-onset focal brain dysfunction, require specific diagnostic and management strategies.
- Existing research often focuses on adult populations, necessitating a clearer understanding of pediatric presentations.
Purpose of the Study:
- To characterize the symptoms, signs, and etiologies of brain attacks in children presenting to the emergency department.
- To establish a foundation for creating a specialized pediatric brain attack clinical pathway.
Main Methods:
- A prospective observational study was conducted on 287 children (1 month to 18 years) experiencing brain attacks.
- Exclusion criteria included epilepsy, hydrocephalus, head trauma, and isolated headache.
- Etiology was determined through clinical data, neuroimaging (CT, MRI), and other investigations, with comparisons to adult studies via meta-analysis.
Main Results:
- Common symptoms included headache, vomiting, focal weakness, and seizures; common signs included focal weakness and ataxia.
- Neuroimaging revealed abnormalities in 27% of CT scans and 62% of MRI scans.
- The most frequent diagnoses were migraine (28%), seizures (15%), Bell palsy (10%), stroke (7%), and conversion disorders (6%), differing significantly from adult proportions.
Conclusions:
- The etiological profile of pediatric brain attacks differs substantially from that observed in adults.
- Stroke was the fourth most common diagnosis in children, highlighting a key difference from adult populations.
- These findings are crucial for informing the development of evidence-based emergency department clinical pathways for pediatric brain attacks.
Objectives:
To determine symptoms, signs, and etiology of brain attacks in children presenting to the emergency department (ED) as a first step for developing a pediatric brain attack pathway.
Methods:
Prospective observational study of children aged 1 month to 18 years with brain attacks (defined as apparently abrupt-onset focal brain dysfunction) and ongoing symptoms or signs on arrival to the ED. Exclusion criteria included epilepsy, hydrocephalus, head trauma, and isolated headache. Etiology was determined after review of clinical data, neuroimaging, and other investigations. A random-effects meta-analysis of similar adult studies was compared with the current study.
Results:
There were 287 children (46% male) with 301 presentations over 17 months. Thirty-five percent arrived by ambulance. Median symptom duration before arrival was 6 hours (interquartile range 2-28 hours). Median time from triage to medical assessment was 22 minutes (interquartile range 6-55 minutes). Common symptoms included headache (56%), vomiting (36%), focal weakness (35%), numbness (24%), visual disturbance (23%), seizures (21%), and altered consciousness (21%). Common signs included focal weakness (31%), numbness (13%), ataxia (10%), or speech disturbance (8%). Neuroimaging included CT imaging (30%), which was abnormal in 27%, and MRI (31%), which was abnormal in 62%. The most common diagnoses included migraine (28%), seizures (15%), Bell palsy (10%), stroke (7%), and conversion disorders (6%). Relative proportions of conditions in children significantly differed from adults for stroke, migraine, seizures, and conversion disorders.
Conclusions:
Brain attack etiologies differ from adults, with stroke being the fourth most common diagnosis. These findings will inform development of ED clinical pathways for pediatric brain attacks.
