Outcome Measures
Primary Outcomes (2)
Clinical Global Impression Scale for AS (CGI-AS)
Medical and neurological evaluation: -Clinical Global Impression Scale for AS (CGI-AS). The scale consists of several categories, from "not assessed" to "extremely severe." Professionals assess various aspects of behavior, communication, and the individual's overall functioning to assign a score on the CGI-AS scale. A higher score indicates a greater severity of symptoms, while a lower score indicates less severity.

Hammersmith Neonatal Neurological Examination (HINE) (for 0-2 years)
Medical and neurological evaluation: Hammersmith Neonatal Neurological Examination (HINE). 26 items that assess neurological function (cranial nerve function, posture, movements, tone, reflexes, and reactions). For neurological function, each item is individually scored on a scale of 0 to 3 based on descriptions and illustrative diagrams, so the total score can range from a minimum of 0 to a maximum of 78.
