PROTECT-Cog means Prevention of Risk fOr cogniTive dEcline through Combined Therapy, a $100 million trial announced July 13, 2026 at AAIC 2026 in London, according to the Association's AAIC announcement. For spouses and partners, it tests lifestyle-plus-drug prevention of decline, with daily support duties established and drug, dosing and site details still pending. The program pairs a proven multidomain lifestyle plan with a metabolism-targeting drug such as a GLP-1 agonist. Prevention here means slowing decline before dementia, not treating memory loss after onset.

What the combined treatment includes
PROTECT-Cog tests coaching in diet, exercise and brain training plus regular group or clinic meetings. A metabolism drug is added for a subset to measure added benefit.
The design separates lifestyle effects from drug effects. One group receives intensive coaching, another receives a lighter structured plan, and only part receives medication.
Who will take part and how groups compare
The trial will enroll older adults at increased risk for decline, as reported by Medscape's trial summary. It compares intensive-coaching lifestyle with structured-lite lifestyle, with drug added in a subset.
That contrast matters for partners. Intensive coaching requires travel, schedule changes and home follow-through. Lite structure still asks for steady habits, but with fewer contacts.
How long follow-up lasts and what it tracks
Participants will be followed for three years with full cognitive and health checks every six months. Visits track decline, onset of mild cognitive impairment, frailty and quality of life.
Three years allows slow change to show. Six-month checks catch shifts in memory, daily function, mood, weight and strength.
Why earlier results shape expectations
PROTECT-Cog builds on U.S. POINTER, described by NeurologyLive's launch report.
POINTER ran two years with 2,111 cognitively unimpaired at-risk adults. Structured diet, exercise, cognitive training and meetings improved global cognition versus self-guided care. PROTECT-Cog asks whether adding a metabolic drug extends that gain.
What spouses and partners can do now
Partners likely affect adherence because success needs sustained exercise, MIND-diet coaching and frequent meetings. No separate spouse enrollment or caregiver benefit has been announced.
Helpful support stays practical. Join walks, keep MIND-style foods visible, guard sleep hours, manage calendars and drive to sessions. Steady routines aid adherence when prevention work lasts years.
