“…[49][50][51][52] Whereas, understandably, such global outcomes are of major interest, future studies could choose to concentrate on specific impairments resulting from alternating hemiplegia of childhood, which include behavioral, sleep, psychological, growth, cardiac, gastrointestinal, epileptic, or otherwise. 19,[51][52][53][54][55][56][57][58][59][60][61][62] The same methodology that we describe in this study can help develop additional scales for future studies of this disease by addressing specific aspects and can also be used for other rare neurodevelopmental diseases.…”

Here, we describe the process of development of the methodology for an international multicenter natural history study of alternating hemiplegia of childhood as a prototype disease for rare neurodevelopmental disorders. We describe a systematic multistep approach in which we first identified the relevant questions about alternating hemiplegia of childhood natural history and expected challenges. Then, based on our experience with alternating hemiplegia of childhood and on pragmatic literature searches, we identified solutions to determine appropriate methods to address these questions. Specifically, these solutions included development and standardization of alternating hemiplegia of childhood–specific spell video-library, spell calendars, adoption of tailored methodologies for prospective measurement of nonparoxysmal and paroxysmal manifestations, unified data collection protocols, centralized data platform, adoption of specialized analysis methods including, among others, Cohen kappa, interclass correlation coefficient, linear mixed effects models, principal component, propensity score, and ambidirectional analyses. Similar approaches can, potentially, benefit in the study of other rare pediatric neurodevelopmental disorders.
