Mental health crisis

In a world where one in four people will be affected by mental or neurological disorders at some point in their lives, the need for accessible mental health care has never been greater. Yet, two-thirds of those suffering never seek help, often due to stigma, cost, or lack of access to care as well as finding professionally accredited practitioners.

It’s affecting individuals, families

Mental health issues are the leading cause of disability worldwide.

The number of people living with anxiety and depressive disorders rose significantly in 2020 due to the COVID-19 pandemic, with initial estimates showing a 26% and 28% increase respectively for anxiety and major depressive disorders in just one year.

As well as businesses, the economy

Mental health issues are responsible for up to 50% of all sick leave in the UK and cost the economy up to £99 billion per year.

In the US, the cost is over 200$ billion.

Mental health-related disability claims have increased by 40% in the last decade
