Standard cognitive tests like the MoCA or MMSE are nearly useless for highly intelligent patients — many score a perfect 30 well into their condition. Real evaluation requires multi-hour neuropsychological testing, brain blood flow measurement, EEG, specialized MRI, and often amyloid and tau PET scans.

Patients find their way to Gayatri Devi through physician referrals, academic publications, and word of mouth — many are still working professionals who want to stay that way. The central challenge is that highly intelligent people are extraordinarily adept at compensating for cognitive decline, often scoring 29 or 30 on standard tests like the MoCA even well into their disease [1] — Gayatri Devi "Standard cognitive tests like the MoCA or MMSE are nearly useless for highly intelligent patients — many score a perfect 30 well into their…" 18:17 . Her evaluation protocol runs two to three days for out-of-town patients and includes multi-hour cognitive testing, brain blood flow measurement via transcranial Doppler, EEG, specialized MRI of hippocampus and parietal lobes, and often amyloid and tau PET scans. She synthesizes results by looking for intra-individual discrepancies — for example, an overall score at the 99th percentile but language at the 10th — as clues to decline that can't be seen in total scores. She explicitly refuses to give a single overall disease stage, preferring to stage each functional domain separately, a position she describes as avoiding dangerous oversimplification.
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.
