Neuroscientist Karyn Frick, a professor of psychological and brain sciences at the University of Wisconsin-Milwaukee, is leading research into how estrogens regulate memory, aiming to create new treatments for age-related memory loss and dementia. By studying sex-based differences in neurobiology, Frick’s work seeks to address why middle-aged females often experience more significant memory decline than their male counterparts, potentially offering new therapeutic options for both sexes.
The Neurobiology of Memory and Aging
Karyn Frick’s interest in memory began in a laboratory at Johns Hopkins University. While studying the neurobiology of memory as an undergraduate, she observed rats navigating mazes, a process that underscored the complexity of brain function. According to the University of Wisconsin-Milwaukee, this early exposure led Frick to earn a PhD in behavioral neuroscience in 1996.
Her research trajectory shifted toward sex-based disparities while she was a faculty member at Yale University and a postdoctoral researcher at Wellesley College. Frick observed that middle-aged female mice exhibited worse memory performance than both males of the same age and younger mice of either sex.

Karyn Frick holds a joint degree in psychology and biology, which she earned from Franklin & Marshall College in 1991. Her career has been dedicated to bridging the gap between basic biological research and practical therapeutic applications for brain health.
Targeting Estrogen to Combat Cognitive Decline
At the Neuroendocrinology of Memory Lab, Frick and her team investigate the role of estrogens in enhancing memory formation. The research explores how the depletion of these hormones during menopause contributes to cognitive symptoms, including memory loss and hot flashes. By isolating the mechanisms through which estrogens protect brain function, the lab aims to develop targeted interventions.
This work led to the 2018 co-founding of Estrigenix Therapeutics Inc. The company’s primary objective is to develop estrogen-like compounds that provide cognitive benefits without the risks associated with traditional hormone therapies, such as increased rates of breast or uterine cancer. According to Frick, the goal is to license these compounds for clinical trials to provide women with a new tool to manage menopausal symptoms.
Broader Applications for Memory Loss
While the initial focus of the research addresses female-specific hormonal changes, the implications extend to broader populations. Estrogens act as a protective mechanism for memory in both men and women. Frick notes that her team’s research aims to provide options for anyone suffering from age-related memory loss or neurodegenerative conditions like Alzheimer’s disease. By unraveling how estrogen regulates the brain, the lab hopes to support future drug-development efforts that could reach the broader market.
Pro Tip:
When evaluating cognitive health, consider that memory is highly individualized. As Frick highlights, even in shared environments, individual biological factors play a significant role in how memories are formed and retained.
Frequently Asked Questions
Why does Karyn Frick focus on estrogen in memory research?
Frick’s research found that middle-aged females often experience more pronounced memory loss than their male counterparts. Her lab investigates how estrogen regulates memory and how the loss of this hormone during menopause contributes to cognitive decline.
What is the goal of Estrigenix Therapeutics?
The company seeks to develop estrogen-like drugs that provide the memory-enhancing benefits of hormones while avoiding the increased cancer risks associated with conventional hormone replacement therapies.
Can this research help men?
Yes. Although the lab focuses on menopausal symptoms, estrogens function as a “shield” for memory in both sexes. The research aims to develop compounds that can combat memory loss in both men and women affected by aging or neurodegenerative diseases.
