Essential features of Asperger’s disorder are severe and sustained impairment in social interaction and the development of restricted, repetitive patterns of behaviour, interests and activities. In contrast to Austistic Disorder there are no clinical significant delays in language, cognitive development or in the development of age-appropriate self-help skills and curiousity about the environment in childhood.
Asperger’s disorder can exist without obvious immaturity in neuro-motor skills being a feature. However, if neuromotor skills are immature, they can affect an individual’s ability to read the non-verbal language of others and to express themselves using non-verbal language. Up to 90% of effective communication involves non-verbal aspects of language and any impairment in the this area can contribute to symptoms of impairment in social interaction and restriction of interests and behaviour. By improving the physical basis for understanding and using non-verbal language, the INPP programme can sometimes help individuals diagnosed with Asperger’s disorder improve their social skills.
As with other complex disorders, the relevance and efficacy of the INPP programmes in the treatment of Asperger’s disorder depends on the developmental history and profile of presenting symptoms in each individual.
