Alzheimer's research has moved through a transformative decade. The first disease-modifying therapies have reached the market, blood-based biomarkers are changing how we detect and stage the disease, and the trial pipeline is broader than it has ever been. If your family is considering a trial, here's an honest guide.
What's being studied
- Anti-amyloid antibody therapies — the current frontier, meant to remove amyloid plaques from the brain
- Anti-tau therapies — targeting a different protein implicated in progression
- Combination approaches pairing anti-amyloid with other mechanisms
- Prevention studies for people with a genetic risk or early biomarker evidence but no symptoms yet
- Mild cognitive impairment (MCI) studies for people with early symptoms who don't meet full Alzheimer's criteria
- Symptom-management studies — for cognition, agitation, sleep disturbance, and other behavioral symptoms
- Diagnostic and biomarker studies — often minimally burdensome and a great starting point for families new to research
Who typically qualifies
Alzheimer's trials are highly specific by design:
- Prevention studies: cognitively normal adults, often 55–75, sometimes with a family history or a positive biomarker
- Early / MCI studies: mild symptoms confirmed by cognitive testing, biomarker evidence of Alzheimer's pathology
- Mild-to-moderate Alzheimer's: a confirmed diagnosis and a specified level of function
- Caregiver requirement: nearly every Alzheimer's trial requires a study partner — usually a spouse, adult child, or close friend — who attends visits with the participant and provides an outside perspective on daily functioning
What visits look like
A typical Alzheimer's trial visit:
- Cognitive testing (30 minutes to a few hours depending on the study)
- Interview with the study partner about daily functioning
- Lab work, including biomarker testing
- Sometimes an MRI or PET scan
- Study medication administration — increasingly a monthly IV infusion for antibody therapies
The commitment is significant: multi-year studies with monthly or bi-monthly visits are common. Travel and caregiver time are usually covered.
Caregiver support
Ethical Alzheimer's trials treat the caregiver as a partner in the study:
- Caregiver time and travel are reimbursed
- Some studies offer respite support or in-home visits when getting to the clinic is difficult
- Caregivers receive updates and are included in decisions about staying in the study
- Support resources — both study-provided and from patient organizations like the Alzheimer's Association — are usually offered
What you keep
- Standard medical care continues, including any FDA-approved Alzheimer's medications the participant is already on (unless the study protocol requires otherwise, which will be clearly explained)
- Insurance for unrelated care is unaffected
- Withdrawal is always available, and study teams will help transition care back to the regular provider
The honest weighing
Alzheimer's trials are demanding — for the participant and for the family. They are also, for many families, the only way to access the newest generation of therapies before they reach broader availability, and the only way to contribute to research that could help future generations. There's no universally right answer. The right question is whether a specific trial's demands fit your family's life and values.
Questions to ask
- What's the drug's mechanism, and what has earlier data shown?
- What are the known side effects, and how are they monitored (many antibody therapies require periodic MRI monitoring)?
- How long is the treatment period, and what happens after it ends — is there open-label extension access?
- What's the study partner's time commitment?
- What support is available between visits?
- Is there transportation help?
- What happens if the participant becomes unable to consent during the study (there is always a defined plan, including a proxy consent process)?
Talking to the primary care team and neurologist
Coordination with your regular care team matters more here than in almost any other area. Make sure everyone is talking to each other — with your permission.

Patient organizations like the Alzheimer's Association also maintain specialized matching services. This is not medical advice; the study team, your neurologist, and your primary care team are your best resources.
