Population ageing is now recognized as one of the major economic and public health challenges of the 21st century. The figures speak for themselves: worldwide, more than one billion people will be over the age of 60 by 2050 [1]. This major demographic shift raises important questions, particularly regarding the maintenance of health and quality of life throughout ageing.
Mental health is defined by the WHO as a state of well-being that enables everyone to cope with the daily challenges of life, to flourish and to contribute to society. Long considered a taboo subject, it is now recognised as a major public health issue, affecting all age groups and social backgrounds.
