Legally, and generally, being of “sound mind” means healthy mental health….that your thinking is clear enough that you are aware of what you are doing, and therefore should be held responsible for your actions. …
‘Mental health’ and ‘Mental illness’ are increasingly being used as if they mean the same thing, but they do not. Everyone has mental health, just like everyone has health. As the World Health Organization famously says, “There is no health without mental health.” In the course of a lifetime, not all people will experience a mental illness, but everyone will struggle or have a challenge with their mental well-being (i.e., their mental health) just like we all have challenges with our physical well-being from time to time.
Mental health is a state of well-being in which the individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully and is able to make a contribution to his or her community.
Mental illness is a recognized, medically diagnosable illness that results in the significant impairment of an individual’s cognitive, affective or relational abilities. Mental disorders result from biological, developmental and/or psychosocial factors and can be managed using approaches comparable to those applied to physical disease (i.e., prevention, diagnosis, treatment and rehabilitation).
