Infantile Spasms / West
Urgent assessment and treatment planning for early infantile spasms.
Infantile spasms are brief body flexion or limb stiffening episodes, usually in the first year of life. West syndrome combines spasms, a characteristic EEG pattern (hypsarrhythmia), and developmental slowing or regression. Early diagnosis and treatment are time-sensitive for developmental outcomes; days matter when suspicion is high. Families should bring event videos and a simple daily log. Treatment response is monitored closely and developmental support should not be delayed.
Scope of assessment
Spasm frequency, relation to sleep-wake cycles, and video recordings are reviewed. Infant EEG, often urgent, searches for hypsarrhythmia or other warning patterns. Underlying structural, metabolic, or genetic causes are investigated. Treatment options such as hormonal therapy, vigabatrin, or other antiseizure medications are discussed by age and cause, with close side-effect monitoring. Developmental milestones are recorded at weekly or monthly intervals, and families receive written or verbal summaries of goals and possible side effects.
When to seek evaluation
Repeated brief “collapse” or bending movements, especially clusters on waking, need urgent assessment. Marked developmental pause or regression cannot wait. Families with a prior West diagnosis should contact promptly if seizure control worsens. Clustered movements on video are an important diagnostic clue.
- Short stiffening clusters on waking
- Movements mistaken for laughing or crying with developmental concern
- Clear developmental plateau
- Sudden regression in a previously typical infant
- Prior EEG report with warning features
Visit and follow-up process
When suspicion is high, EEG may be planned the same or next day. Families are asked for videos and an event diary. After treatment starts, spasm count, EEG response, and developmental milestones are monitored closely. Early physiotherapy and vision support are not delayed. Response is often assessed every one to two weeks initially.
Clinical approach
This condition is treated as an urgent neurological situation with a clear timeline and contact pathway. Measurable goals replace vague pessimism because treatment response varies. Multidisciplinary follow-up including development and nutrition is standard. When spasms respond, developmental support programs are accelerated. Same-day or next-day EEG remains a priority when clinical suspicion is high.
