How fast are you really aging, and what could that mean for brain health? Aladdin H. Shadyab, Ph.D., explores the gap between chronological age and biological age, and why that difference matters for long-term health. Shadyab describes tools that use information from blood to estimate how quickly the body is aging, including approaches that look beyond the body as a whole to consider aging in specific systems. He connects faster biological aging with higher risk for age-related disease and declines in physical and cognitive function, and discusses how blood-based biomarkers may offer earlier signals of processes linked to Alzheimer’s disease. Shadyab also highlights lifestyle and treatment findings that may support healthier aging and longer survival. Series: "Stein Institute for Research on Aging" [Health and Medicine] [Show ID: 41073]

Circadian timing shapes how we sleep, feel, and function each day. Satchidananda Panda, Ph.D., Salk Institute, describes what the ideal circadian rhythms of a day look like.

Biological resilience underpins healthy aging, and Anthony Molina, Ph.D., investigates how people resist, adapt to, and recover from age-related stressors. Molina defines three domains of resilience linked to aging and studies “life course” resilience using the Rancho Bernardo Study, a longitudinal cohort that starts in 1972 and tracks cognitive, sensory, physical function and comorbidities. His group analyzes trajectory scores from tasks such as the trail-making test and examines thousands of blood molecules to identify patterns that distinguish exceptionally resilient participants. Laboratory experiments show how age-related molecular profiles relate to mitochondrial function and ATP production. Molina’s team also tests behavioral and nutritional interventions in rigorously designed clinical studies, combining molecular biomarkers of biological age with measures of physical performance, cognition, sensory abilities, and mental well-being.

Circadian timing shapes how we sleep, feel, and function each day. Satchidananda Panda, Ph.D., Salk Institute, explains that keeping daily light, meals, movement, and sleep in step with the body’s internal clock supports alertness, metabolism, and recovery. Panda notes that evening light and late eating can make it harder to fall asleep and may work against healthy glucose control, while thoughtful timing of activity can improve energy and rest. He highlights that when we take medicines matters because the body’s response changes across the day. Travel and shift work challenge these rhythms, but simple habits with light exposure, meal timing, and sleep can ease the strain. Panda also describes ongoing efforts testing practical routines, including limited daily eating windows paired with light and activity strategies.

Psychological resilience in later life examines how older adults adapt after adversity and cultivate everyday practices that sustain well-being and purpose. Elizabeth W. Twamley, Ph.D., introduces and guides a discussion on mental health and resilience among older adults. Ellen E. Lee, M.D., characterizes resilience as dynamic learning oriented toward flourishing and urges a low threshold for seeking help when symptoms overwhelm daily routines. Sidney Zisook, M.D., presents grief as adaptation to loss, distinguishes acute from integrated grief, and explains how intense waves of emotion gradually become less frequent and more manageable; he views psychedelic therapies as promising but not ready for routine treatment. Marti E. Kranzberg shares practical approaches that include mindfulness, journaling, gratitude, movement, sleep, pain management, creative arts, time in nature, community, and purpose.

Cognitive resilience grows from small, consistent habits that keep the brain adaptable. Fadel Zeidan, Ph.D., frames mindfulness as mental training that improves attention, processing, and the way people relate to pain. Erin E. Sundermann, Ph.D., underscores modifiable pathways to healthier aging, highlighting movement, social connection, hearing support, and lifelong learning as mutually reinforcing drivers of brain health. Raenne C. Moore, Ph.D., centers practical strategies that translate into daily life, including routines, planned breaks, reducing distractions, and attending to anxiety or depression. Carolyn Dunmore, an older adult community Mmmber, exemplifies resilience through steady activity, purposeful community roles, faith, self-compassion, and the “use it or lose it” mindset. Together, Zeidan, Sundermann, Moore, and Dunmore point to a clear theme: everyday practices accumulate to support memory, attention, and well-being as people age.

Targeting the biology of aging offers a path to stronger resilience and longer health. John C. Newman, M.D., Ph.D., explains that aging arises from measurable cellular processes, often called hallmarks of aging, including changes involving mitochondria, stem cells, cellular senescence, inflammation, and protein quality control. Newman describes how basic science in model organisms reveals mechanisms that can be manipulated to extend healthy lifespan and guide therapies. Emerging approaches aim either to strengthen stress responses that make cells more resilient or to address downstream consequences. Many clinical studies across the country now test interventions that target aging, supported by national efforts to standardize methods and expand training. Newman also investigates ketone bodies as energy sources that influence inflammation, muscle preservation, and other processes relevant to frailty and recovery.

Healthy aging starts with physical resilience, the body’s ability to withstand and recover from stress. Maile Young Karris, M.D., defines the concept and sets the stage for practical strategies that match real-world needs. Ryan J. Moran, M.D., M.P.H., recommends simple routines such as wall push ups, posture alignment, and chin tucks, and he links posture and vision to fall prevention; social connection helps people stick with movement. Theodore Chan, M.D., F.A.C.E.P., F.A.A.E.M., explains that age alone is a poor predictor of outcomes in acute care and that functional resilience strongly influences decisions. Gail Levine emphasizes accountability, community, and balanced nutrition. Moran highlights protein needs of about 1 to 1.2 grams per kilogram plus calcium with possible vitamin D, and he favors plant focused eating with limited processed foods.

Heather E. Whitson, MD, MHS explores how resilience—the ability to recover and adapt after stress or illness—changes across the lifespan. She explains that bounce back slows with age and that people age at different rates, influenced by biology, lifestyle, and environment. Studies connect lower inflammation, stronger cellular health, and emotional well-being to better recovery, such as regaining mobility after hip fracture or coping with persistent pain. Whitson also highlights how changes in the brain, like the buildup of amyloid and tau proteins, begin years before memory problems, underscoring the importance of early prevention. She points to practical steps that support resilience at any age: staying active, eating a Mediterranean style diet, managing blood pressure and blood sugar, protecting vision, engaging socially and mentally, prioritizing sleep, avoiding harmful exposures, and preventing injuries.

Danielle K. Glorioso, LCSW, explores the complex nature of grief, emphasizing that it is a lifelong, evolving response to loss rather than something to “get over.” She explains the differences between acute grief, integrated grief, and prolonged grief disorder, highlighting how factors like attachment, personal history, and circumstances of death can influence the grieving process. Glorioso outlines how prolonged grief can impair daily functioning and discusses effective treatments, including a structured therapy program that facilitates adaptation. She also examines resilience as a skill that can be strengthened through emotion regulation, cognitive flexibility, social support, and meaning-making. Drawing on both professional expertise and personal loss, Glorioso offers practical strategies for coping, supporting others, and finding hope while honoring the memory of loved ones.

Michael J. Wilkinson, M.D., F.A.C.C., F.N.L.A., explores the science and clinical evidence behind intermittent fasting and its role in promoting cardiometabolic health. He explains how aligning eating patterns with the body’s natural circadian rhythms can improve weight, blood pressure, glucose regulation, and other risk factors, especially in individuals with metabolic syndrome or type 2 diabetes. Wilkinson highlights promising results from time-restricted eating studies conducted in collaboration with UC San Diego and the Salk Institute, where narrowing the daily eating window led to improved metabolic markers and potential benefits beyond weight loss. He also outlines practical tips for safely adopting this lifestyle approach and stresses the importance of ongoing research.

Sarah Banks, Ph.D. explores why Alzheimer's disease affects women differently than men, emphasizing distinct patterns in tau pathology, cognitive testing bias, and treatment response. She explains how women tend to show a rapid buildup of tau during early cognitive decline, which may contribute to their higher prevalence of Alzheimer's. Banks also highlights how common diagnostic tools may overlook symptoms in women and how approved treatments may offer less benefit for them. Her research at UC San Diego investigates key sex-based differences in risk factors, including sleep apnea, diabetes, and exercise. One study reveals that over 70% of participating women had undiagnosed sleep apnea. Another focuses on Black women, using blood biomarkers to identify overlooked risks and improve care.
