Mental health
Main article: Mental health
The World Health Organization describes mental health as "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".[31] Mental health is not just the absence of mental
illness.[32]
Mental illness is described as 'the spectrum of cognitive, emotional,
and behavioral conditions that interfere with social and emotional
well-being and the lives and productivity of people. Having a mental
illness can seriously impair, temporarily or permanently, the mental
functioning of a person. Other terms include: 'mental health
problem', 'illness', 'disorder', 'dysfunction'.[33]
Roughly one fifth of all adults 18 and over in the US are considered
diagnosable with mental illness. Mental illnesses are the leading
cause of disability in the US and Canada. Examples
include, schizophrenia, ADHD, major depressive disorder, bipolar
disorder, anxiety disorder, post-traumatic stress
disorder and autism.[34]
Many factors contribute to mental health problems, including:
Biological factors, such as genes or brain chemistry
Life experiences, such as trauma or abuse
Family history of mental health problems[35]
