In this episode, Lauren & Matt speak with Neguine Rezaii, MD, an Assistant Professor of Neurology at Harvard Medical School and a Board-Certified Neuropsychiatrist at Mass General Hospital. Dr. Rezaii’s research focuses on using natural language processing and artificial intelligence to improve the detection and classification of neurodegenerative disorders.

Dr. Rezaii talks about her recent study, “Voiceprints of Cognitive Impairment: Analyzing Digital Voice for Early Detection of Alzheimer’s and Related Dementias,” which explores how artificial intelligence can analyze short speech samples to identify subtle signs of cognitive impairment. The study used speech recordings from 120 individuals and found that features such as pauses, word choice and the specificity of language can help distinguish cognitive impairment and Alzheimer’s disease.

The conversation also explores how a simple 30-second speech test could potentially be used in clinical settings to support earlier detection and monitoring of cognitive impairment, as well as the challenges and ethical considerations that come with using AI to analyze something as personal as a person’s voice.

In this episode, Lauren & Matt speak with Neil Mehta, PhD who is the associate dean for research and a professor in the Department of Epidemiology at the University of Texas Medical Branch in Galveston. Dr. Mehta’s research focuses on US life expectancy trends, the effects of obesity on disability and mortality, the sources of socioeconomic status disparities in mortality, and patterns of health in the United States and Europe.

Dr. Mehta talks about a recent manuscript from the NIA-funded TRENDS study called “Trends in Memory Function and Memory Impairment Among Older Adults in the United States and Europe, 1996 to 2018.”, which looks at data from several sources to compare trends in memory function across 13 different countries.

Welcome back to Season 6 of Minding Memory! In this episode, Lauren & Matt speak with Dr. Katherine (Kate) Possin, who holds the John Douglas French Alzheimer’s Foundation Professorship at the University of California, San Francisco Fein Memory & Aging Center.

Dr. Possin talks about the Care Ecosystem, a telephone and web-based model that provides ongoing education, support, care planning, and coordination for people living with dementia and their care partners. They’ll dig into how the Care Ecosystem was developed, and what studies have shown about its impact on people living with dementia.
