Health Matters

Perimenopause is having a moment, but for many women, it can still feel confusing, unpredictable, and difficult to navigate. In this episode of Health Matters, host Courtney Allison speaks with Dr. Cassandra Simmons, chief of obstetrics and gynecology at NewYork-Presbyterian and Columbia, about what’s really happening during this transitional phase.

Dr. Simmons explains that perimenopause is driven by fluctuating levels of estrogen, progesterone, and testosterone, which can begin as early as a woman’s 30s and last for several years. These hormonal shifts can lead to a wide range of symptoms—from hot flashes and night sweats to brain fog, mood changes, joint pain, and sleep disruption.

The conversation focuses on vasomotor symptoms like night sweats and why they can significantly impact energy, sleep quality, and daily functioning. Dr. Simmons also discusses the emotional and cognitive effects of perimenopause, including the common feeling of “just not yourself.”

Finally, Dr. Simmons outlines treatment options in three categories: holistic approaches such as supplements and lifestyle changes, non-hormonal prescription therapies, and hormone replacement therapy. She emphasizes individualized care, the importance of understanding the whole patient, and how modern hormone therapy has evolved to be safer and more tailored than in the past.

Many people worry about memory loss and cognitive decline as they age. In this episode of Health Matters, host Courtney Allison speaks with Dr. Matthew Fink, neurologist-in-chief at NewYork-Presbyterian and Weill Cornell Medicine, about how lifestyle choices—especially diet—can help protect the brain.

Dr. Fink explains the MIND diet, a combination of the Mediterranean and DASH diets, which emphasizes whole foods like leafy greens, berries, fish, nuts, and olive oil while limiting salt, sugar, and ultra-processed foods. He breaks down how key nutrients such as B vitamins and antioxidants support brain metabolism, reduce inflammation, and may slow the aging process.

The conversation also highlights the brain’s high energy demands and why proper nutrition is essential for cognitive function. Dr. Fink shares research showing that healthy lifestyle interventions can significantly lower the risk of dementia and discusses the broader benefits of the MIND diet for heart health and stroke prevention.

Finally, Dr. Fink outlines additional habits that support brain health, including regular physical activity, quality sleep, and social connection, emphasizing that even small, gradual changes can lead to meaningful long-term benefits.

Tick bites and concerns about Lyme disease are increasing, especially during warmer months. In this episode of Health Matters, host Courtney Allison speaks with Dr. Laura Kirkman and Dr. Karen Acker of NewYork-Presbyterian, Weill Cornell Medicine, and NewYork-Presbyterian Komansky Children’s Hospital of Children’s Hospital of New York about what people should know about ticks and Lyme disease.

Dr. Kirkman explains the types of ticks found in the U.S., where they live, and how they attach to the body. She emphasizes that not every tick bite leads to Lyme disease—it depends on the tick species, whether it carries the bacteria, and how long it remains attached.

Dr. Acker explains how Lyme disease is transmitted and outlines the stages of infection, including early symptoms such as the characteristic bullseye rash, fever, and fatigue, as well as less common complications involving the nervous system, heart, or joints.

The conversation also covers how Lyme disease is diagnosed and treated, including when testing is necessary and when a preventive dose of antibiotics may be recommended after a tick bite.

Finally, the doctors share practical strategies to prevent tick bites—from tick checks and proper clothing to repellents and safe tick removal—and discuss emerging concerns like lone star ticks and alpha-gal syndrome. Their key message: with awareness and simple precautions, you can significantly reduce your risk.

Kindness may seem simple—but it has powerful effects on our health, relationships, and longevity.

In this episode of Health Matters, host Courtney Allison speaks with Dr. Warren Ng, a psychiatrist at NewYork-Presbyterian’s Center for Youth Mental Health, about what it really means to be kind and why it matters more than ever. Dr. Ng explains that kindness begins with intention and connection, often leading to small but meaningful actions that can ripple outward to others.

The conversation explores the biology of kindness, including how it increases oxytocin—often called the “feel-good” hormone—while boosting serotonin and reducing stress hormones like cortisol. These changes can support heart health, lower anxiety, and even strengthen the immune system.

Dr. Ng also discusses research linking kindness and social connection to longer life expectancy and better cognitive health, including studies on volunteering and brain function in older adults. He introduces the concept of “kindfulness,” or being intentional about kindness, and offers practical tips on how to incorporate it into daily life—whether through helping others, expressing gratitude, or practicing self-compassion.

Joints play a critical role in how we move, stay active, and maintain independence—but joint pain and arthritis can make everyday activities challenging.

In this episode of Health Matters, host Courtney Allison speaks with Dr. Nana Sarpong, an orthopedic surgeon at NewYork-Presbyterian and Columbia, about how joints function and what happens when cartilage wears down. Dr. Sarpong explains the difference between mechanical osteoarthritis and inflammatory forms of arthritis like rheumatoid arthritis, including how each impacts joint movement, pain, and stiffness.

The conversation covers conservative treatment strategies such as anti-inflammatory medications, physical therapy, bracing, and injections—along with when surgery becomes the right option. Dr. Sarpong also explains how modern joint replacement surgery works, how long implants now last, and what recovery looks like.

Dr. Sarpong debunks common myths, including whether cracking your knuckles is harmful, if weather really affects joint pain, and the idea that people with arthritis should avoid movement. His key message: motion really is lotion—and staying active is essential for protecting your joints and preserving long-term mobility.
