Gill Livingston, MD, is an academic psychiatrist in the UK specializing in dementia research. As the leader of the Lancet Standing Commission on Dementia Prevention, Intervention, and Care, she has spearheaded landmark reports in 2017, 2020, and 2024. These reports provide new research, meta-analyses on life-course risk factors, and an overview of current interventions—offering critical insights into preventing and delaying a significant proportion of dementia cases.

Dr. Livingston works directly with individuals with suspected or confirmed dementia and their families. Her interdisciplinary approach integrates epidemiological and biopsychosocial research to develop and test evidence-based interventions. She recently co-led the successful DREAMS trial, which focused on improving sleep in dementia patients, and is now conducting a two-year follow-up study. Additionally, she and her colleagues are developing ENHANCE—an app-based intervention with personalized coaching designed to help individuals at high risk of cognitive decline maintain brain health.
