Insights
Apparent life-threatening episodes (ALTE) in children may signal underlying epilepsy. Early diagnosis is often delayed, but ictal EEG and brain imaging can confirm epileptic seizures presenting as ALTE.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Neurophysiology
Background:
- Apparent life-threatening episodes (ALTE) are a diagnostic challenge in pediatrics.
- Epilepsy can present initially as ALTE, complicating diagnosis.
- Gastroesophageal reflux is a common differential diagnosis that can obscure epileptic manifestations.
Observation:
- This study retrospectively analyzed 6 pediatric cases where ALTE was the first seizure manifestation.
- Interictal electroencephalogram (EEG) findings were often normal, delaying diagnosis.
- Abnormal cerebral imaging was noted in some patients.
Findings:
- Ictal EEG recordings were the most effective diagnostic tool for confirming epileptic seizures presenting as ALTE.
- In cases with only interictal EEGs, abnormal cerebral imaging provided valuable diagnostic support.
- Prompt recognition of epilepsy is crucial for appropriate management.
Implications:
- Highlights the importance of considering epilepsy in children with ALTE.
- Emphasizes the diagnostic utility of ictal EEG and neuroimaging in these complex cases.
- Suggests improved diagnostic pathways to reduce delays in epilepsy diagnosis for children presenting with ALTE.
Abstract:
Apparent life-threatening episodes (ALTE) can be the first manifestation of an epileptic seizure in children. However, the diagnosis of ALTE is generally delayed because the interictal EEG often appears normal and the presence of gastroesophageal reflux may mislead the diagnosis of the epileptic manifestation. We report 6 children with epilepsy who presented an ALTE as their first seizure manifestation. The retrospective analysis of our cases demonstrated that ictal EEGs, when available, appeared to be the most helpful test to confirm the diagnosis, although an abnormal-appearing cerebral imaging was also contributive in the patients when only interictal EEGs were available.

Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
Seizures: Classification
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:
