Before monoclonal antibodies, Gayatri Devi was already deploying a complex toolkit: cholinesterase inhibitors, memantine, valacyclovir, WATCHMAN procedures to get patients off blood thinners, and transcranial magnetic stimulation since 2008. Today these tools remain core elements of her multimodal approach alongside anti-amyloid therapies.

Two patient stories anchor the episode's most hopeful moments. First: a woman in her seventies who sought out Gayatri Devi after seeing her on television, was confirmed to have Alzheimer's via spinal tap, started on lecanemab, cleared her amyloid — and then showed no tau on a subsequent tau PET scan [1] — Gayatri Devi "One patient cleared her brain amyloid and then subsequently showed no tau on a tau PET scan — a response Gayatri Devi describes as so remar…" 1:12:20 . Gayatri Devi describes her disbelief: she 'refuses to believe' the pathology is truly gone and is waiting for a confirmatory spinal tap. Second: an identical twin whose sibling is in a care facility; Gayatri Devi's patient, who also had rheumatological heart disease requiring a mechanical valve and Coumadin therapy, was started on monoclonal antibody therapy with intensive monitoring, never developed side effects, and cleared her amyloid — dramatically outperforming her genetically identical twin. Both cases illustrate that individual immune biology may be as important as the drug itself.
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.
Self-help fails because people are sold one universal cure by the hyper-responders who had a transformative result from it. The real problem is context: every method works for the right person at the right time, which is almost never you just because the author says so.
Spencer Greenberg was once so socially anxious his heart pounded just approaching a stranger. His therapist gave him homework: go to a bar alone, talk to 5 strangers. Starting with asking for the time, he worked up to asking men for hugs — and his anxiety fell dramatically in 6 months.
A person who flies regularly but obsessively checks weather forecasts before every flight is not doing exposure therapy — they're teaching their brain that flying is only safe with the ritual. Safety behaviors prevent the brain from ever learning that the feared thing is actually fine.
The worry-time technique assigns all worries to one scheduled slot (e.g. 5 PM). Every time a worry surfaces, you write it down and ban yourself from engaging with it until that time. When 5 PM arrives, most worries feel trivial and the act of batch-worrying exposes how little it actually accomplishes.
In a randomized study of 20 habit techniques, 'habit reflection' stood out: recall a past habit you successfully built, write down what helped you succeed, then apply those same strategies to your new habit. It works because it's self-adapting — it uses whatever worked for YOU.
The tiny habits technique — always having a minimal version of your habit you can do when life gets in the way — keeps the mental machinery of habit formation from breaking. Paradoxically, people given a tiny-habit fallback option were MORE successful at the full habit, not less.
Fears and worries act like playground bullies — they want to ambush you. But when you deliberately seek them out and choose the time of engagement, they lose their power. The volitional act of starting the fight on your own terms is one of CBT's most underappreciated insights.
Most downtime defaults are things you regret immediately after — phone scrolling, binge TV. 'Glad you did it' activities meet the same need for rest but leave you feeling like you spent your time well. The switch from a bad screen to a documentary, a book, or a walk costs almost no extra effort but compounds into identity over time.
You rarely control your first reactive thought. But you can train your second thought — the response to the trigger — by asking whether your initial reaction is the most helpful one and replacing it with something equally true but more constructive. Over time, that second thought becomes automatic.
