World Mental Health Day raises public awareness about mental health issues. The day promotes open discussion of mental disorders, and investments in prevention, promotion and treatment services. The treatment gap for mental, neurological and substance use disorders is formidable especially in poor resource countries.

This year the theme is "Investing in mental health".
