Mental illness is complicated and fragile, and can be brought on or exacerbated by combinations of factors including family history, early childhood challenges, genetics, socio-economic conditions, environmental conditions, trauma, and poor lifestyle.

Rates of mental illness are rising, according to the World Health Organization (WHO): “The burden of mental disorders continues to grow with significant impacts on health and major social, human rights and economic consequences in all countries of the world” It is unclear whether the data trend is due to better detection and diagnosis, changes in environment or genetics, the aging world population and life expectancy, or economic and political stresses.
