The $100 million PROTECT-Cog Alzheimer's study announced in 2026 tests lifestyle coaching plus a metabolism-targeting drug, and spouses and partners face clear questions about joining as study partners. PROTECT-Cog means Prevention of Risk fOr cogniTive dEcline through Combined Therapy, a prevention trial for at-risk older adults. The Alzheimer's Association announced the study on July 13, 2026, at its international conference in London, according to the Association's AAIC announcement. It tests whether a multidomain lifestyle program plus a metabolism-targeting drug reduces cognitive decline, mild cognitive impairment, and dementia.

What is PROTECT-Cog testing?
The trial compares intensive structured lifestyle coaching with a structured-lite version that offers the same core content with fewer touchpoints. A subset of participants also receives a metabolic drug, as reported by Medical Daily in its coverage of the Association's announcement. The approach builds on U.S.
POINTER, a 2-year trial at five sites with 2,111 cognitively unimpaired at-risk adults, mean age 68.2, where structured exercise, MIND-diet support, and cognitive training improved global cognition, according to NeurologyLive reporting. PROTECT-Cog adds medication to that lifestyle foundation. The specific GLP-1 or similar drug had not been selected at announcement, so results are still years away.
Why are spouses asked to take part?
Most Alzheimer's trials require a study partner who knows the participant well. That person attends visits and reports on memory, daily function, and medication adherence, according to a Synapticure clinician guide.
For spouses and live-in partners, that role often falls to you. It means shared driving, shared scheduling, and shared follow-through. Before enrolling, talk through whether both of you can stay involved for the full study period.
What would three years involve?
Participants will be followed for three years with comprehensive cognitive and health assessments about every six months, according to Medscape's AAIC launch report. Expect repeated memory testing, health checks, and coaching contacts.
Intensive coaching means more appointments, homework, exercise sessions, diet changes, and brain-training tasks. The lite version covers the same topics with less contact. Ask which group allows a drug, how visits differ, and what happens if health, caregiving, travel, or work disrupts attendance.
Which questions should you ask the research team?
The Alzheimer's Association and National Institute on Aging advise spouses to ask about purpose, drug safety and side effects, placebo odds, visit schedule, duration, and how the family doctor stays informed. Bring a short written list and take notes.
