Five Things We Learned About Alzheimer’s Disease in 2025


Five Things We Learned About Alzheimer’s Disease in 2025

The year 2025 brought major progress in Alzheimer’s research, diagnosis, and care. From new testing options to lifestyle insights, these developments are helping reshape what’s possible for people living with the disease.

1. Lifestyle Changes Improve Cognitive Health

The Alzheimer’s Association’s U.S. POINTER study showed that lifestyle interventions can significantly improve cognitive function in older adults at risk for decline. Structured programs — including coaching on exercise, nutrition and cognitive training — produced the strongest results. With over 2,100 participants, the study’s success is shaping new initiatives, including a web-based brain health tool and virtual provider training.

2. FDA Clears First Alzheimer’s Blood Tests

For the first time, the FDA cleared two blood tests to support Alzheimer’s diagnosis. The Lumipulse test (approved in May) helps specialists assess amyloid plaque presence in adults 50+ with symptoms. The Elecsys pTau181 test (cleared in October) is now available to primary care providers to help rule out Alzheimer’s-related brain changes. While not standalone diagnostics, these tests may reduce the need for invasive or costly procedures.

3. Americans Want Early Diagnosis

A national Alzheimer’s Association survey found that 79% of adults 45+ want to know if they have Alzheimer’s before symptoms interfere with daily life. An overwhelming 91% would take a simple diagnostic test. Nearly three in five respondents said they’d accept some risk from a medication that could slow disease progression — underscoring the demand for early, accessible testing and treatment.

4. New At-Home Option for Alzheimer’s Treatment

The FDA approved weekly at-home injections for the Alzheimer’s treatment Leqembi for patients who have completed the initial IV phase. This option can ease the burden on families by reducing travel and clinic visits. Continued treatment has been shown to help preserve memory and thinking skills over time.

5. ALZPro Launches for Dementia Professionals

The Alzheimer’s Association launched ALZPro, a new online hub offering clinical guidelines, training, and research resources for professionals. The platform supports high-quality, person-centered dementia care and helps clinicians stay current with rapid advances in the field.

“As we look ahead, the Alzheimer’s Association remains committed to accelerating progress and ensuring every community benefits from these advances,” said Delia Jervier, Executive Director of the Alzheimer’s Association Illinois Chapter.
