Parkwood Institute cares for those with severe, complex or persistent mental illness who need the expertise of a specialized team. Care may be provided through hospitalization, ambulatory clinics or through outreach in the community. People who come into care have varying diagnoses which can include depression, schizophrenia and other conditions. Mental illness is a disease that affects the brain and is not caused by one single factor, but a complex interaction between genetic, biological, environmental and social factors. Treatment and rehabilitation can help a person return to everyday living.
