Overview
Infantile spasms (West syndrome) is an age-dependent epileptic encephalopathy characterized by sudden, brief, generalized muscle contractions. 1Diagnosis
Clinical presentation of sudden, brief, generalized spasms
Electroencephalography (EEG) showing hypsarrhythmia or burst-suppression pattern
Exclusion of other causes of seizures or developmental regression
Developmental regression often observed 1Management
First-line treatment: Adrenocorticotropic hormone (ACTH) 1
- Dose and duration not specified in the abstract
Adjunctive therapy: Vitamin B6 1
Consider alternative treatments if ACTH is ineffective or contraindicated 1Special Populations
Pediatrics: Focus on early diagnosis and intervention to prevent developmental delays 1Key Recommendations
Evaluate cardiac autonomic function, particularly heart rate variability, in patients with infantile spasms to identify autonomic dysfunction 1 (Evidence: Moderate)
Initiate treatment with ACTH combined with vitamin B6 to improve both seizure control and autonomic function 1 (Evidence: Moderate)
Monitor response to treatment with ACTH, including potential improvements in heart rate variability parameters, to assess efficacy 1 (Evidence: Moderate)References
