Creativity 'closely entwined with mental illness'

Creativity is often part of a mental illness, with writers particularly susceptible, according to a study of more than a million people.

Writers had a higher risk of anxiety and bipolar disorders, schizophrenia, unipolar depression, and substance abuse, the Swedish researchers at the Karolinska Institute found.

They were almost twice as likely as the general population to kill themselves.

The dancers and photographers were also more likely to have bipolar disorder.
