Many clinical trials of Alzheimer's disease (AD) treatments have failed, including drugs that lower amyloid, the protein that builds up in the brain in AD. One likely reason is that AD differs from person to person, so finding subgroups that a treatment could target is a priority.

What they work on

  1. Determine how cortisol response to acute stress, induced with the Trier Social Stress Test and measured in saliva, relates to memory and executive-function performance after stress in people with mild cognitive impairment due to Alzheimer's disease.
  2. Test whether APOE genotype and polygenic risk scores for Alzheimer's disease change the link between the stress-hormone response and cognitive performance after acute stress.
  3. Identify predictors of cognitive decline and neurodegeneration at 2-year follow-up, drawing on stress responses, genetic risk and blood-based Alzheimer's biomarkers.
  4. Repeat these analyses separately in 60 men and 60 women to identify sex-specific predictors of stress-induced cognitive impairment and later decline.

More about the research

Many studies suggest that people who are especially sensitive to stress face a higher risk of AD. That makes stress sensitivity a promising candidate. Yet careful lab studies of the body's hormonal stress response have rarely been combined with careful study of patients.

Why it matters

With many amyloid-lowering treatments for Alzheimer's disease failing, new treatment targets are needed. If heightened stress-hormone reactivity predicts faster decline in people with mild cognitive impairment, it could flag a group of at-risk individuals for future prevention trials. These trials could target the HPA stress system. The work could also reveal whether men and women need different approaches.
