One patient cleared her brain amyloid and then subsequently showed no tau on a tau PET scan — a response Gayatri Devi describes as so remarkable she 'refuses to believe' the pathology is gone. Another patient, an identical twin of a facility-dwelling Alzheimer's patient, did so well on monoclonal therapy despite having a mechanical heart valve and being on Coumadin.

The mechanism of ARIA becomes clinically concrete in this segment: anti-amyloid antibodies clear amyloid not just from brain parenchyma but also from the tunica media (walls) of small brain arteries. This removal disrupts vascular continuity, causing first fluid leakage (ARIA-E, edema) and then extravasation of actual blood (ARIA-H, hemorrhage); in severe cases with concurrent blood thinners, the result can be fatal [1] — Gayatri Devi "Anti-amyloid antibodies clear amyloid not just from brain substrate but also from the walls of small brain arteries. This disrupts vascular…" 1:03:30 . Gayatri Devi's response is systematic: all patients undergo regular MRI monitoring, and in over five years of practice she has only encountered one case of symptomatic ARIA — all other cases were detected on imaging alone. For patients with persistent ARIA-E, she preemedicates with steroids before each subsequent infusion, borrowing from the treatment approach for spontaneous cerebral amyloid angiopathy-related inflammation. One dramatic case — a APOE4 homozygous man who developed significant ARIA-E and microhemorrhages at month 18 without any symptoms — illustrates both the risk and the importance of radiographic surveillance.
Anti-amyloid antibodies clear amyloid not just from brain substrate but also from the walls of small brain arteries. This disrupts vascular integrity, causing fluid leakage (ARIA-E, edema) and then actual blood extravasation (ARIA-H, hemorrhage). In severe cases with blood thinners or large vessel disruption, it can be fatal.
Despite years of liberal monoclonal antibody use, Gayatri Devi has seen only one case of symptomatic ARIA; all other cases were detected only on MRI.
AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
Fei-Fei Li's father had liver surgery performed by a da Vinci robot guided by a surgeon. The result: 10 times less blood loss than a typical procedure. This isn't replacement — it's the gold standard of human-machine collaboration, where the human's judgment and the robot's precision combine.
US drug overdose deaths fell from 110,000 to roughly 70,000 — the biggest CDC-recorded single-year drop ever. Men's rates fell 27% in one year, and the steepest decline of all was among 15–24-year-olds, down 37%. The crisis narrative around young men needs to make room for signs of genuine progress.
Kessler thought his grief expertise would protect him. It didn't. When his son David died unexpectedly, he found himself on the floor — and eventually realized that acceptance alone wasn't enough. That unmet need became the sixth stage: finding meaning.
Grief isn't just death — it's any unwanted change. Kessler lectured at Coca-Cola and General Mills not because they had lots of funerals, but because change management is grief management. People who grieve well live well.
Witnessing someone's grief isn't just emotional support — it's an essential act of healing. Kessler argues grief is a severance and connection heals it. But real witnessing has two steps: seeing the pain AND affirming the person's capacity to recover.
Avoiding grief isn't free — it's exhausting. Kessler's beach ball metaphor nails it: pushing a small balloon down is easy, but holding a massive beach ball underwater takes constant, draining energy. Unattended feelings don't disappear; they just consume you.
Most people try to control their environment to avoid triggers. Kessler flips this entirely: triggers aren't problems to manage around — they're a detailed map to your pain and your healing. Every trigger points directly to what needs attention.
Running from pain doesn't leave it behind — it accelerates the chase. Whatever we run from pursues us, and whatever we face transforms us. Both Kessler and Lewis Howes testify to knowing both roads firsthand.
