Alzheimer’s disease can begin developing years before memory and thinking problems become noticeable. Iris Broce-Diaz, Ph.D., of UC San Diego is developing accessible, noninvasive, and cost-effective tools to help primary care physicians and neurologists identify people at higher risk earlier. Her models combine information from cognitive assessments, brain imaging, genetics, and PET scans to estimate the likelihood that mild cognitive impairment will progress within five years. Combining multiple measures improves the models’ ability to separate higher- and lower-risk patients. Broce-Diaz also plans to add women-specific factors, including menopause history, hormone therapy, reproductive history, endocrine markers, and symptoms. The goal is to support better referrals, guide monitoring, and help eligible patients consider treatment sooner. Earlier risk assessment could also strengthen clinical trials and make dementia care more useful across different health systems. Series: "Motherhood Channel" [Health and Medicine] [Show ID: 41632]

Men with non-obstructive azoospermia may undergo microscopic testicular sperm extraction, or mTESE, without knowing whether sperm will be found. Kun Tan, Ph.D., of UC San Diego explains how molecular semen analysis could provide a noninvasive way to predict the procedure’s outcome. The assay uses stage-specific germ cell markers identified through single-cell RNA sequencing, then measures those markers in semen with qPCR. Because semen contains germ cells from different stages of sperm development, their molecular signals may reflect what is happening inside the testes. Tan shows how the assay predicts whether sperm retrieval was successful and can identify where sperm development may be blocked. The research could help couples planning IVF or ICSI avoid unnecessary surgery, reduce financial and emotional burdens, and receive more detailed information about male infertility before treatment.

Chronic pain in older adults can affect mobility, mood, sleep, social connection, and independence. Una Makris, M.D., M.Sc., UC San Diego and VA San Diego Healthcare System, explains why musculoskeletal pain is common later in life and why medications or procedures alone may not meet the needs of many patients. Drawing on her work in rheumatology and geriatrics, Makris describes how pain and depression can reinforce each other, making it important to address both together. She highlights an age-friendly behavioral coaching approach that uses motivational interviewing, values-based goal setting, physical activity, and social support to help people reconnect with meaningful activities. By focusing on small, safe increases in movement, this research points to practical ways to support better function, quality of life, and healthy aging.
