By Dr Kike Olajide, Wellcome Global Health Clinical Research Fellow, Centre for Psychiatry, Imperial College London.

Globally, the number of people with depression and anxiety is on the rise – up from 416 million in 1990 to 615 million in 2013. The World Health Organisation estimates that mental illness is now the leading cause of disability worldwide, accounting for over 15% of years lost due to disability (YLD). In addition to disability, common mental illnesses such as depression can lead to suicide. If you are aged 15 to 29 and living in Europe, the thing most likely to kill you, is you – suicide is the leading cause of death in this age group.
