Denne udelukkelse understøttes af, at de primære symptomer ved autistisk forstyrrelse ikke kan behandles vellykket med Risperdal, da målsymptomerne ved autisme som Risperdal har vist sig yderst effektive over for, er associerede symptomer snarere end et bredt spektrum af symptomer på sygdommen.
This exclusion is supported by the fact that the primary symptoms of the autism disorder cannot successfully be treated with Risperdal because the target symptoms in autism for which Risperdal has demonstrated its most robust efficacy are associated symptoms rather than a broad spectrum of symptoms of the disease.
