  • From Night Sweats to Brain Fog: How to Navigate Perimenopause

    From Night Sweats to Brain Fog: How to Navigate Perimenopause
    Jul 1 2026

    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.

    Chapters

    00:00 – What Is Perimenopause?
    How hormone changes drive symptoms and why timing varies for every woman

    03:15 – Hormones and Symptoms Explained
    The role of estrogen, progesterone, and testosterone in sleep, energy, and mood

    07:45 – Why Night Sweats Disrupt Daily Life
    Understanding vasomotor symptoms and their impact on sleep and function

    12:00 – Treatment Options and Lifestyle Support
    From supplements and therapy to hormone replacement and exercise

    Key Topics Covered

    Perimenopause definition
    Hormone fluctuations (estrogen, progesterone, testosterone)
    Night sweats and hot flashes
    Brain fog and cognitive symptoms
    Sleep disruption and fatigue
    Emotional and mood changes
    Weight, metabolism, and muscle mass
    Bone health and estrogen decline
    Holistic supplements and nutrition
    Hormone replacement therapy (HRT)
    Non-hormonal treatment options
    Lifestyle strategies for symptom management

    Takeaway message: Perimenopause can affect nearly every part of the body, but understanding what’s happening hormonally is the first step toward feeling better. With a combination of lifestyle changes, supportive therapies, and personalized care—including hormone treatment when appropriate—women can manage symptoms and maintain their health and well-being through this transition.

    What is the MIND Diet and How Does it Protect Your Brain?
    Jun 17 2026
    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.

  • How to Protect Against Ticks and Lyme Disease

    How to Protect Against Ticks and Lyme Disease
    Jun 3 2026

    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.

    Chapters

    00:00 – Understanding Ticks and Their Risks
    Overview of tick species, where they live, and how they interact with humans

    04:30 – What Is Lyme Disease?
    How Lyme disease is transmitted, early symptoms, and stages of infection

    08:45 – Diagnosis, Treatment, and Tick Removal
    When to test for Lyme disease, antibiotic options, and how to safely remove a tick

    12:00 – Preventing Tick Bites and Emerging Concerns
    Prevention strategies, protecting kids and pets, and lone star tick risks

    Key Topics Covered

    Tick species in the U.S.
    Where ticks live and how they attach
    Lyme disease transmission
    Early symptoms of Lyme disease
    Bullseye rash and warning signs
    Diagnosis and antibody testing
    Antibiotic treatment and prevention
    Proper tick removal techniques

    Takeaway Message

    A tick bite does not automatically mean Lyme disease. By checking for ticks regularly, removing them promptly, and using simple prevention strategies, you can significantly reduce your risk. When caught early, Lyme disease is highly treatable—making awareness and prevention your best tools for staying safe outdoors.
