Despite the significant investments in mental health services and related digital solutions, poor mental health is still becoming a problem for an increasing number of people.
According to WHO close to 15% of the world’s population is estimated to experience a mental disorder at any given time.
The mood and anxiety disorders only in the EU are the leading cause of work disability and are accounting for up to 50% of chronic sick leave. In US an estimated 21.4% of adults experience any mood disorder at some time in their lives (NIH).
