Mental Illness

Mental Illness

Everyone in Ontario is affected by mental illness. Twenty percent are directly affected by mental illness during their lifetime, while the remaining 80% are indirectly affected through family, friends and colleagues.1

The number of Ontarians requiring mental health services is increasing. While the percentage of all health care users in Ontario rose by 4% between 1992 and 1998, the percentage of patients requiring mental health services rose by 13%.2

Of those requiring mental health services, the majority are affected by mild forms of mental illness. Diagnoses include mild depression, seasonal affective disorder (SAD), as well as anxiety disorders and phobias.

The mental health system in Ontario is funded to serve the seriously mentally ill. Three dimensions of illness are used to identify the most seriously mentally ill: diagnosis, disability, and duration.3

  • Diagnoses includes schizophrenia, bipolar disorder and chronic depression.
  • Disability refers to the extent to which the individual's ability to function in one or more major life activities is limited. These life activities include basic living skills (eating, bathing), instrumental living skills (managing finances, appropriate use of medication) and functioning in social contexts.
  • Duration refers to the ongoing nature of the illness. This not only refers to continuous evidence of a disorder, but also to intermittent episodes with periods of full recovery.
