Journal of the American Geriatrics Society: Social Determinants of Health and Mild Cognitive Impairment in a Representative Community Sample

Study Map Showing Sample from Allegheny County

Social determinants of health are non-medical factors of daily life that influence health outcomes. A review of factors influencing cognitive impairment in older adults presented a range of community-level structural and social determinants of health, distinguished from individual risk and protective factors. Investigators led by Mary Ganguli, MD, MPH (Professor of Psychiatry, Epidemiology, and Neurology), analyzed...

New Research in Diverse, Community-Based Populations of Older Adults

New Research in Diverse, Community-Based Populations of Older Adults

Mary Ganguli, MD, MPH (Professor of Psychiatry, Epidemiology, and Neurology), has worked for more than 35 years on the epidemiology of the aging brain and late-life mental disorders. In two studies recently published in Alzheimer Disease & Associated Disorders, members of Dr. Ganguli’s team reported on effective strategies to recruit diverse study participants, as well as the results from an investigation of...

Recent Clinical Innovations in Perinatal and Geriatric Psychiatry

Pregnant Woman and African American Older Man

Recent papers from the Department of Psychiatry examine clinical initiatives around integration of behavioral health teams in OB-GYN clinics, fetal inflammatory response and risk for psychiatric disorders, and the association between benzodiazepine use and risk of cognitive impairment among older adults. Impact of colocated behavioral health on OB-GYN clinicians' rate of perinatal behavioral health diagnosis and...

A Population-Based Study of How Diabetes, Blood Pressure and Body Mass Index Contribute to Late-Life Cognitive Decline

Dr. Mary Ganguli

The delivery of effective medical and psychiatric treatments in later life can be complicated by the presence of multiple co-occurring conditions. Three such conditions—obesity, diabetes and dementia—co-occur in older adults more frequently than can be expected by chance. While studies have demonstrated that diabetes, high blood pressure and high body mass index in midlife predict dementia in late life, in late...
