The charity states: “Some of the core characteristics of autism are having ‘repetitive behaviours’ and highly-focused interests.
“Stereotyped examples of these include rocking backwards and forwards, and a fascination with trains.
“However, in autistic women and girls these behaviours and interests may be similar to those of non-autistic women and girls, such as twirling hair and reading books, and as such may go unnoticed despite the greater intensity or focus typical for autistic people.”
