ALZHEIMER’S ASSOCIATION LAUNCHES “PROTECT-COG” STUDY TO TEST U.S. POINTER LIFESTYLE AND GLP-1 OR SIMILAR DRUG TO CUT RISK OF COGNITIVE DECLINE

LONDON, July 13, 2026 /PRNewswire/ — The Alzheimer’s Association immediately introduced the launch of the PROTECT-Cog Study (Prevention of Risk fOr cogniTive dEcline by means of Combined Therapy), a first-of-its-kind world scientific trial designed to guage whether or not combining a confirmed multidomain life-style intervention with a metabolism-targeting drug, equivalent to a GLP-1 agonist, can additional cut back the chance of cognitive decline, gentle cognitive impairment (MCI), and dementia in at-risk older adults.

The $100 million effort was introduced immediately for the primary time on the Alzheimer’s Association International Conference^® (AAIC^®) 2026 in London. 

Building on the success of the Alzheimer’s Association-led U.S. POINTER, and LatAm FINGERS research, PROTECT-Cog represents the subsequent part in advancing analysis targeted on threat discount/prevention methods for Alzheimer’s and different ailments that trigger dementia.

“PROTECT-Cog builds directly on what we learned from U.S. POINTER and takes the next critical step in prevention science,” mentioned Maria C. Carrillo, Ph.D., chief science officer and medical affairs lead on the Alzheimer’s Association, and principal investigator of the research. “By testing a combined approach that targets both lifestyle and biology, we have the opportunity to better understand how to meaningfully reduce the risk of cognitive decline before symptoms begin.”

“Now is the time to accelerate bold, science-driven strategies to prevent or delay dementia,” mentioned Joanne Pike, DrPH, president and CEO of the Alzheimer’s Association. “The PROTECT-Cog Study reflects our commitment to leading large-scale, rigorous research that explores and expands urgently needed treatment options, including how combining interventions may deliver even greater benefit for those at highest risk.”

A rising physique of analysis demonstrates that modifiable life-style components — together with bodily exercise, diet, cardiovascular well being, sleep, and social engagement — play a vital position in mind well being and dementia threat. The U.S. POINTER study showed {that a} extremely consultant inhabitants of at-risk older Americans who adopted a structured, multidomain life-style intervention skilled considerably better cognitive advantages in contrast with these utilizing a self-guided strategy. These enhancements have been equal to roughly one to 2 years of cognitive benefit, together with further advantages in decreasing frailty and sleep apnea, and enhancing blood strain regulation.

At the identical time, rising proof from massive real-world healthcare datasets means that GLP–1 receptor agonists could cut back dementia threat by 40–70% in contrast with different diabetes medicines. Other research recommend that they’re most protecting in opposition to dementia in sufferers with weight problems or a excessive BMI. This is additional supported by quite a few mechanistic research suggesting GLP-1 agonists play a task in mind irritation and metabolism, and vascular well being. There is clearly a necessity to raised perceive the timing and use of those therapies in prevention.

The PROTECT-Cog Study will enroll older adults who’re at elevated threat for cognitive decline and evaluate two life-style intervention approaches—a structured program with intensive teaching and help and a structured-lite program with the identical core content material however fewer participant touchpoints—to guage their results on cognitive well being. The research will even assess the influence of including a drug that helps more healthy metabolism and immune perform to determine which intervention mixture is only at delaying gentle cognitive impairment whereas evaluating results on frailty, high quality of life, and total well being. Participants will probably be adopted for 3 years, with complete cognitive and well being evaluations performed each six months.

“The Alzheimer’s Association is uniquely positioned to lead this next generation of dementia prevention research. Through our leadership of U.S. POINTER, LatAm FINGERS, and the World Wide FINGERS Network, the Association has established the global infrastructure, scientific expertise and partnerships required to conduct a study of this scale,” mentioned Heather M. Snyder, Ph.D., senior vice chairman of medical and scientific relations on the Alzheimer’s Association, and employees lead on this undertaking.
