Mental illness affects over 57 million adults in the US and has wide-ranging impacts on the entire family unit. Families experience social isolation, financial hardship, and increased stress as about 40% of those discharged from psychiatric care return to family. Children of parents with mental illness are at greater risk for health and social issues. Siblings and other family members also struggle with the illness. Reducing family stress requires understanding caregiver needs, providing information and support, and involving the family in the treatment process.
