The study in an analysis of the relationship between theatrical art and the mental health impairments associated with Autism Spectrum Disorder. Apart from using theatre for education and social and clinical practice, we have a look at progressive, international and professional theatre institutions, which contribute significantly to the discussion on neurodiversity. Despite the fact that modern medicine has an impact on the change to the social paradigm towards the acceptance of people with mental impairments, the level of stigmatisation within society is still quite high. The study examines, within theatre or by theatrical means, the forms of inclusion which contributes to a cultural diversity that is an extension of an open and tolerant society.
