Serious Mental Illness Hub
The National Council for Mental Wellbeing is committed to providing resources to improve mental health care and recovery services for people with serious mental illness (SMI) and first episode psychosis.
SMI is defined as a mental, behavioral or emotional disorder that results in serious functional impairment, which substantially interferes with or limits one or more major life activities. SMI impacts individuals across the lifespan and is often disruptive for those who experience it.

14.6 million
adults aged 18+ diagnosed with SMI.

4.3 million
did not receive mental health treatment.
The National Council supports mental health providers, individuals and communities that are directly or indirectly involved in SMI care and treatment. We strive to empower individuals, professionals, families and communities to improve the identification, treatment and recovery journey for those living with SMI.
