Seizures in childhood cerebral adrenoleukodystrophy

Area of Science:

• Neurology
• Genetics
• Pediatrics

Background:

• Childhood cerebral adrenoleukodystrophy (CCALD) is a severe demyelinating disease.
• Seizures are a known but not fully characterized symptom in CCALD.
• Understanding seizure prevalence is crucial for early diagnosis and management.

Purpose of the Study:

• To determine the prevalence of seizures in male children with CCALD.
• To explore the relationship between seizures and disease severity/progression in CCALD.
• To compare seizure incidence in CCALD with X-linked adrenoleukodystrophy (X-ALD) without cerebral involvement.

Main Methods:

• Retrospective observational cross-sectional study.
• Inclusion of male patients under 18 with genetically confirmed X-ALD and CCALD brain MRI findings.
• Comparison with X-ALD patients without cerebral lesions; statistical analysis of clinical and MRI variables.

Main Results:

• 29% of 86 male children with CCALD experienced seizures.
• Seizure severity correlated with poorer functional status and higher MRI/Loes scores.
• Seizures were more frequent in CCALD (29%) than in X-ALD without cerebral involvement (5.7%).

Conclusions:

• Seizures are a significant clinical feature in CCALD.
• X-linked adrenoleukodystrophy (X-ALD) should be considered in male children presenting with new-onset seizures.
• Seizure occurrence and severity increase with disease advancement in CCALD.
