  • Brain Fog and Autoimmune  Encephalitis: A Window Into Immune-Driven Cognitive Dysfunction

    Brain Fog and Autoimmune Encephalitis: A Window Into Immune-Driven Cognitive Dysfunction

    • Brain Health
    • Cognitive Function

    Cognitive dysfunction does not require neuron loss. It can arise from reversible interference with how brain cells communicate. Brain fog may reflect the same underlying biology, existing on a spectrum of immune-related synaptic disruption, rather than as a fundamentally different process. Autoimmune encephalitis is a neuroinflammatory condition in which immune responses target components of the central nervous system. This condition often causes problems with memory, attention, processing speed, and behavior, which frequently emerge before dramatic neurological signs develop. These changes can occur even when brain imaging is normal and before irreversible injury is present. [1][2]

    Why You Still Feel Tired Despite Normal Thyroid Labs

    When symptoms persist despite normal thyroid labs, the next step is not necessarily more thyroid hormone. It is better questions. Questions that look beyond a single lab value and toward the broader energetic context. The EAS framework offers a more accurate and more compassionate interpretation of symptoms are “not thyroid-related”.

    Hypothyroidism and Depression: Why They’re So Often Confused

    • Thyroid Health

    The overlap between hypothyroidism and depression is not a coincidence. It reflects shared physiology, shared neuroendocrine pathways, and a long history of clinical observation that continues to be supported by modern research. Understanding this overlap requires moving beyond symptom checklists and into the biology of how thyroid hormones interact with the brain.

    Beyond the Uterus: Why Progesterone Still Matters After Hysterectomy

    The idea that women without a uterus don’t need progesterone is misleading. While progesterone is no longer required to protect the endometrium after hysterectomy, it still plays important systemic roles throughout the body. Progesterone receptors exist in the brain, bones, breasts, blood vessels, and immune cells, meaning it can influence mood, anxiety, sleep quality, cognition, bone formation, breast comfort, inflammation, and metabolic and cardiovascular function. Data shows the therapeutic use of bioidentical progesterone in the right context, though it is not a cure-all and must be paired with healthy  lifestyle choices.
