In France, one person out of five will be affected by a mental disorder during lifetime. Such disorders cause many handicaps in these people’s private and professional lives, and generate many costs for the French society. Mental disorders cause an estimated loss of 92 billion euros in GDP every year (3.7% of GDP), equivalent to the combined budgets of the French national education, higher education, and research sectors. Technology is the key to curbing this phenomenon. Our study “Digital tools, an opportunity for our mental health” showed that they are the first cause of long-term sick leave and the first cause of disability. Introducing new digital technologies would improve prevention, detection, and management of disorders, allowing the patients in question’s early mortality to decrease. The use of innovation in mental health would facilitate access to care, thus increasing the use of therapies whilst improving healthcare professionals’ practice.
