Insights
Migrating partial seizures in infancy are a rare, severe epilepsy syndrome. This study describes two infants with this condition, highlighting their intractable seizures and poor outcomes.
Area of Science:
- Pediatric Neurology
- Epileptology
- Clinical Neuroscience
Background:
- Intractable partial seizures in infants pose significant diagnostic and therapeutic challenges.
- Early-onset epilepsy syndromes require precise characterization for appropriate management.
- The syndrome of migrating partial seizures in infancy (MPSI) is a rare, severe condition.
Observation:
- Two infants presented with intractable partial seizures originating from multiple brain regions.
- Seizures were resistant to all antiepileptic drug therapies.
- No developmental progress was observed after seizure onset.
Findings:
- Both infants exhibited multifocal epileptiform activity on electroencephalograms.
- The clinical presentation and EEG findings met the diagnostic criteria for MPSI.
- Postmortem examination in one infant revealed no hippocampal sclerosis.
Implications:
- This case study underscores the diagnostic criteria and clinical course of MPSI.
- Further research is needed to understand the etiology and pathophysiology of MPSI.
- Improved diagnostic and therapeutic strategies are crucial for infants with MPSI.
Abstract:
Two infants presented at 3 weeks and 3 months of age with intractable partial seizures. Extensive investigations failed to identify an underlying cause. There was no response to antiepileptic drug therapy and no developmental progress following the onset of the seizures. In both infants there was a distinctive pattern of seizures that arose independently from multiple regions of both hemispheres. Interictal electroencephalograms revealed multifocal epileptiform activity. The infants died aged 9 and 12 months. One underwent postmortem examination, which was normal with no hippocampal sclerosis. These infants fulfill the diagnostic criteria of the syndrome of migrating partial seizures in infancy described by Coppola and colleagues in 1995.

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:
