What is it about schizophrenia that lends itself to creativity? One important aspect of the condition is what is diagnostically known as 'loosening of association'. Words and concepts can combine in the speech and writing of schizophrenics in ways of association that are highly unusual. In refractory schizophrenics, these associations lead to word-salad type expressions that run counter to meaning. In some schizophrenics however, this unusual and loosened conceptual play can lead to quite successful creative outcomes. Writing, especially in mediums such as poetry, associations of words and concepts has to be loosened via an imaginary obfuscation which gives a pleasant unusualness. With the right vocabulary, this unusualness can lead to expression of beauty which are at the heart of poetry. Schizophrenics are in a perfect position to capitalise on this linguistic gymnastics, due to the above mentioned symptom - loosening of association.
There may be other aspects of schizophrenia that lend the condition to acts of creativity. I will leave these to further blog posts in the future.
