She's had APOE4/4 for 10 years. She's still sharp at 72.

Yes, and Phoenix member Donna Dorans is a concrete example. She learned she was APOE4/4 at age 62 through a Yale research study, and 10 years later at 72 she remains cognitively sharp. Her approach evolved over a decade of experimentation: a daily supplement stack, hormone replacement therapy, food-as-medicine (caviar, salmon, sardines), and iterative dropping of interventions that did not work for her biology. Her key lesson for newly diagnosed carriers is that protocols are personal and require experimentation over years, not months. She also met 80-year-olds in the Bredesen program who started late and still saw results, reinforcing that it is never too late to begin.

Donna Dorans' current stack after 10 years of refinement includes MitoCU for mitochondrial support, curcumin (her favorite, which eliminated her word-finding problems), N-acetylcysteine (NAC), sulforaphane (broccoli extract, newly added), magnesium glycinate for sleep, low-dose melatonin for sleep, zinc and thiamine based on her genetics, and Pendulum Akkermansia for blood sugar. She also uses hormone replacement therapy and thyroid medication. Food-as-medicine includes daily caviar (her DHA/EPA source), regular salmon and sardines, and one egg per day for choline. Total monthly cost is over $400. Her comment: 'You can't put a price on your cognition.'

Donna's drop list is instructive because it shows personalization matters. She dropped liposomal glutathione (redundant with NAC), L-theanine (did nothing for her), lithium orotate (caused insomnia), citicoline (also caused insomnia), and strict keto. She is a lean-mass hyper-responder, meaning her cholesterol shot up dramatically on keto and her sleep suffered, so she had to abandon the protocol despite its popularity among APOE4 carriers. This illustrates that APOE4 carriers need to track their individual response rather than following generic protocols, and willingness to stop things that do not work is as important as willingness to start things that might.

No. Donna Dorans, who started her protocol at 62 and remains sharp at 72, met participants in Dr. Dale Bredesen's ReCODE program who were 80 and older when they started and still saw measurable improvement. The underlying biology supports this: the brain retains plasticity throughout life, interventions still reduce inflammation and improve metabolic health at any age, and even if the long-term prevention window has closed, short-term cognitive gains and quality-of-life improvements are achievable. Her advice to older newly diagnosed carriers: don't freak out, there are protocols, and you have control over this.

Donna has spent a decade refining her protocol. Here's what's currently in her stack: Supplements: MitoCU (mitochondrial support) Curcumin (this one's her favorite — she had word-finding problems, started curcumin, and "boom, gone") N-Acetylcysteine (NAC) Sulforaphane (broccoli extract, just added) Magnesium glycinate (sleep) Melatonin (low dose, sleep) Zinc and thiamine (based on her genetics) Pendulum Akkermansia (probiotic for blood sugar) Hormones: HRT (hormone replacement therapy — she knows it's controversial, made a personal choice to stay on it) Thyroid medication Food-as-medicine: Caviar daily (yes, really — high in DHA and EPA, her omega-3 source) Salmon, sardines, fatty fish regularly One egg a day for choline What she dropped: Liposomal glutathione (redundant) L-theanine (did nothing for her) Lithium orotate (caused insomnia — out the door) Citicoline (also caused insomnia) Strict keto (she's a lean mass hyper-responder — her cholesterol shot up and she couldn't sleep) Total monthly cost? Over $400. "You can't put a price on your cognition," she said. I agree.
