Brain fog won't lift — what is the first oMeds step?

Short answer

Brain fog is routed by hormonal context: TRT for men with confirmed low testosterone, BHRT for peri/menopausal women, NAD+ for longevity-axis cellular fog. Thyroid, B12, and glucose are screened before any pathway is initiated.

Full answer

Brain fog rarely has a single cause. Provider review screens thyroid (TSH, free T3, free T4), B12, ferritin, and fasting glucose first — correctable inputs that often resolve fog without further escalation. Persistent cases are routed by hormonal context: men with confirmed low total and free testosterone are evaluated for Testosterone Optimization; women in perimenopause or menopause with cycle and biomarker context matching are evaluated for BHRT. Patients with documented cellular decline, post-illness cognitive lag, or longevity-axis goals are evaluated for NAD+. Every initiation requires the standardized biomarker panel and synchronous video review.

Mental cloudiness drivers?
Brain fog most often reflects thyroid dysfunction, perimenopause, B12 deficiency, sleep disruption, insulin resistance, or chronic inflammation. Provider review screens systematically.
Can low T cause brain fog?
Yes. Cognitive symptoms — slowed processing, difficulty with focus, reduced verbal recall — are increasingly recognized in low testosterone, alongside fatigue and mood. Cognitive symptoms often improve when testosterone is restored to the optimization range.
