Advanced Hormone Testing: Beyond Standard Lab Panels
Most standard hormone panels miss the diagnosis. Not because the labs are wrong, but because they answer only one question when the clinical picture requires three. A patient presents with classic estrogen dominance symptoms — weight gain, mood instability, heavy...
Neuroinflammation From Persistent Viral Infections
A common practitioner mistake: attributing post-viral cognitive symptoms to lingering viral load when the actual driver is ongoing neuroinflammation. The virus may be gone. The immune response it triggered may not be. Dr. Datis Kharrazian's clinical training at the...
Chronic Infections Driving Autoimmune Disease Development
Most practitioners are trained to treat infections acutely and move on. The deeper clinical problem is what happens when the infection never fully resolves — or when a latent pathogen reactivates months or years later, and the immune system response it triggers begins...
Mitochondrial Function Testing for Longevity Optimization
Most practitioners ordering longevity panels are measuring the wrong things. Telomere length, inflammatory markers, and lipid oxidation panels tell you something about aging — but they don't tell you why the cell is failing. Mitochondrial health longevity testing gets...
Neuroendocrine-Immune System Integration in Aging
Most aging protocols treat hormones, inflammation, and neurological decline as separate problems requiring separate interventions. That diagnostic habit is the core reason so many aging patients plateau. The nervous system, endocrine system, and immune system do not...
Blood Sugar Imbalances: Hidden Trigger for Mood Instability
A common practitioner mistake is treating anxiety and depression as isolated neurological events while metabolic dysfunction drives the entire presentation. When a patient's mood symptoms don't respond to standard interventions, blood sugar dysregulation is frequently...
Beyond Serotonin: Functional Medicine Approach to Mood Disorders
The serotonin hypothesis of depression has driven psychiatric treatment for decades. It has also produced a patient population that takes SSRIs indefinitely, never fully recovers, and cycles through medication adjustments while the underlying physiology goes...
Neuroinflammation and Depression: Clinical Assessment Tools
Most practitioners treating depression are still asking one question: which neurotransmitter is deficient? Research in neuroimmunology has been asking a different one for years: which inflammatory pathway is active? The clinical gap between those two questions is...
Beyond Alzheimer’s: Hidden Causes of Cognitive Decline
Most practitioners ordering a cognitive workup are asking one question: is this Alzheimer's or isn't it? That's the wrong question. Cognitive decline has a differential diagnosis as broad and mechanistically distinct as any other complex chronic condition, and...
Neuroinflammation and Blood-Brain Barrier in Dementia
A practitioner's most common mistake with dementia patients is treating the brain last. The gut gets addressed, the liver gets supported, the hormones get balanced — and the organ driving the patient's decline receives the least direct clinical attention. Dr. Datis...
Critical Windows for Brain Development in Children
Most practitioners understand that early childhood matters for brain development. Fewer appreciate how precisely timed that window is — or how many distinct biological systems must converge correctly within it. The Kharrazian Institute's pediatric neurodevelopment...
Neuroimmunology in Childhood Developmental Disorders
Most developmental disorder evaluations begin at birth or after. The neuroimmunology research suggests they should begin before conception. Maternal immune function during pregnancy is now recognized as one of the most significant determinants of fetal brain...
