Electroencephalogram during and after an acute attack of asthma in children
Insights
Electroencephalograms (EEGs) in children experiencing asthmatic attacks showed no changes, contrary to prior research. This suggests that if EEG abnormalities are present, a complicating factor should be considered.
Area of Science:
- Pediatric Neurology
- Respiratory Medicine
- Clinical Neurophysiology
Background:
- Asthma exacerbations can impact various physiological systems.
- Previous studies have suggested potential links between asthma attacks and electroencephalogram (EEG) findings.
- The neurological effects of acute asthma in children require further clarification.
Purpose of the Study:
- To investigate whether acute asthmatic attacks in children are associated with changes in EEG recordings.
- To compare EEG patterns during and after asthma exacerbations with baseline recordings.
- To determine if asthma severity correlates with EEG alterations.
Main Methods:
- Electroencephalograms (EEGs) were performed on 12 pediatric patients hospitalized for asthma exacerbations.
- Three EEG recordings were obtained: during the attack, immediately post-attack, and several weeks later.
- Asthma severity was categorized (moderate, severe, very severe), and blood gas levels were monitored.
Main Results:
- No significant changes were observed in the serial EEG recordings related to the asthmatic attacks.
- Blood gas levels showed expected changes corresponding to asthma severity.
- Other laboratory values, including electrolytes and glucose, remained within normal limits.
Conclusions:
- Acute asthmatic attacks in children do not appear to cause direct changes in EEG patterns.
- The presence of EEG abnormalities during an asthma exacerbation suggests a potential complicating factor.
- Further investigation is warranted to identify factors that may cause concurrent EEG changes in pediatric asthma.
Abstract:
EEGs were recorded in 12 children who were admitted to hospital because of an asthmatic attack. One EEG was recorded during the attack, one immediately after, and a third EEG several weeks later. The severity of the attack was classified as moderate in eight children, severe in three and very severe in one child. There was a corresponding change in the blood gases, but other laboratory values (electrolytes, glucose, etc.) were normal. Contrary to previous findings, no change was seen in the three successive EEG recordings which had been related to the attacks. It is therefore concluded that an asthmatic attack as such does not give rise to changes in the EEG, and a complicating factor should be suspected if such changes are seen.
