Alex Weigand, PhD, (she/they) is a Clinical Neuropsychology Fellow at the UCSF Edward and Pearl Fein Memory and Aging Center, part of the UCSF Weill Institute for Neurosciences. Their research focuses on identifying cognitive, biological, and neuropsychiatric markers of age-related neurodegenerative diseases, with an emphasis on the preclinical stages of Alzheimer’s disease. They use multimodal approaches—including neuropsychological testing, brain imaging, and biofluid biomarkers—to better understand disease heterogeneity and improve early detection. Their work also examines tau PET imaging, neuromodulatory brain systems, and cerebrovascular health.
Clinically, Weigand is interested in neuropsychological assessment across the lifespan, from attention-deficit/hyperactivity disorder (ADHD) and learning disorders to neurodegenerative diseases, including dementia. They also have an interest in the cognitive effects of primary psychiatric conditions and dialectical behavior therapy (DBT).
Before joining UCSF, Weigand completed a PhD in Clinical Psychology through the Joint Doctoral Program at San Diego State University and the University of California, San Diego, with a major area of study in neuropsychology and a quantitative emphasis. They earned a bachelor's degree in Philosophy-Neuroscience-Psychology and Psychological & Brain Sciences from Washington University in St. Louis.
