This paper argues for a standardized use of definitions and outcome measures in publications on West syndrome. Specific recommendations include the need for a validated definition of hypsarrhythmia, the use of the term non-symptomatic and abandoning the terms cryptogenic and idiopathic, talking about underlying disease association and not aetiology or cause and defining a clinical response to mean that no clinical evidence of a spasm has been seen for a specified time – 48 h was suggested. Patients should be followed up to report development – perhaps at 12–15 months and again at 2 and 5 years. Disease free survival should be reported. Side effects need to be seen as adverse events producing risk modification. Outcomes should be blind whenever possible. A consensus group will take these and other suggestions forward – please contact mailto:[email protected] if you are interested in taking part.
