Non-drug interventions for patients with Alzheimer’s are both effective and cost-effective, study shows

A Brown-led research team found that four dementia-care interventions saved between $2,800 and $13,000 in societal costs and reduced nursing home admissions while improving quality of life. Non-drug interventions have been shown to be effective in clinical trials and can help people with dementia stay safely at home longer.
