THE EARLY DETECTION INITIATIVE
Don’t Wait to Ask
There are now treatments that can slow Alzheimer’s. Early detection gives you more time to live well. Ask your doctor about a cognitive test.
WHY EARLY DETECTION MATTERS
Alzheimer’s Isn’t What it Used to Be.
For most of the last century, there was little reason to press for an early answer. Nothing could change the course of the disease, and a diagnosis offered information without options. That is no longer the case.
The changes that lead to Alzheimer's disease begin in the brain years, often more than a decade, before memory or thinking are noticeably affected. By the time symptoms are clear to the people around you, a great deal has already taken place.
The treatments now available slow the disease rather than reverse it. What they protect is the ability you still have, which is why the point at which the disease is found matters as much as the diagnosis itself.
What has changed
Three developments over the past several years have changed what an early diagnosis is worth. Each one is a reason to raise cognitive health with your doctor sooner than you might have before.
TREATMENT
For the first time, FDA-approved therapies can slow the progression of Alzheimer's disease. They are approved only for people in the earliest stages, which means eligibility is decided by how early the disease is found. A delayed diagnosis can close a door that an earlier one would have kept open.
Therapies now slow the disease.
TESTING
Evaluation once meant months of referrals and specialized imaging. Today it can begin with a brief assessment that your own doctor can perform, and newer blood-based tests can support physicians in confirming what is behind a change far faster than was previously possible.
What an early answer makes possible
Eligibility for treatment. The therapies that slow Alzheimer's are approved only for people in the early stages of the disease. Whether they are an option for you depends largely on when the disease is identified.
Finding a different cause. Thyroid conditions, vitamin B12 deficiency, sleep disorders, depression, and the side effects of common medications can all affect memory and thinking. Many are treatable, and some resolve entirely once addressed.
Answers come faster than they used to.
TME
Time to begin treatment. Time to address other conditions affecting your thinking. Time to make decisions about your care and your future while those decisions are still entirely yours. And time to live well.
An early answer is time you get back.
Protecting cognition now. Blood pressure, hearing loss, sleep quality, and medication interactions all influence how well the brain works. Each can be managed, and knowing where you stand now can help you form a plan.
Access to clinical trials. Most studies of Alzheimer's treatments enroll people in the earliest stages of disease. An early diagnosis is frequently what makes participation possible at all. There are also studies available for cognitively healthy individuals and those with mild cognitive impairment.
Decisions made in your own voice. Preferences about care, finances, and legal arrangements are best set by the person they concern. An early answer leaves time to put those preferences in writing while everything is still clear to you.
Time for your family to prepare. Families who know early can work through questions of housing, care, and cost at a reasonable pace. Families who learn late often face the same decisions all at once, under real pressure.
More than four in ten older adults showing signs of cognitive impairment are never diagnosed.
Memory changes are easy to overlook, and a routine appointment with your doctor rarely leaves time to explore them. Asking directly is what moves things forward.

Cognitive Changes are Worth a Conversation
Almost everyone notices something as they get older. A name that takes a moment longer to arrive. The reason you walked into a room, gone by the time you get there. Most of the time this is ordinary, and your doctor will tell you so.
What doctors look for is a different pattern: changes that keep happening, and changes that have started to get in the way of an ordinary day. Telling one from the other is not something you have to work out on your own. That is what the appointment is for.
AGE-RELATED CHANGE
Thinking slows somewhat with age. Recall takes longer, names surface a beat late, and a list becomes useful where it once wasn't. Daily life continues without adjustment.
MILD COGNITIVE IMPAIRMENT
Change impacts daily function.
Questions are repeated within a single conversation. The thread of a discussion becomes difficult to hold. Tasks performed for years take longer or are completed incorrectly. Family members have often observed the same changes. Many people with mild cognitive impairment remain stable for years, and some improve. Alzheimer's disease is one of several possible causes.
DEMENTIA
Persistent impairment, daily life is affected.
Managing medications, handling finances, navigating familiar routes, or maintaining a household have become difficult. Dementia describes this level of impairment rather than a single disease. Alzheimer's disease is its most common cause, and identifying the underlying cause determines the appropriate treatment.
Some causes of cognitive change are reversible.
Thyroid disorders, vitamin B12 deficiency, sleep apnea, depression, and interactions between common medications can all produce symptoms that look like early dementia. They are found through the same evaluation, and many of them can be treated and resolved. Not asking does not protect you from a diagnosis. It only delays knowing which of these you are dealing with.
Slower recall, function holds.
WHAT TO EXPECT
A Cognitive Test is a Conversation, Not a Verdict.
Here is what happens during a visit.
BEFORE THE VISIT
THE VISIT
Write down what you've noticed, and say it when you book.
A few specifics are more useful than a general worry: when it started, what changed, whether anyone else has mentioned it. Tell the scheduler you want to discuss memory concerns so the appointment is long enough. Bring a partner, adult child, or friend — they often noticed changes first.
YOUR RESULTS
A score and a starting point - not a diagnosis.
A cognitive assessment cannot diagnose Alzheimer's on its own. It tells your doctor whether what you're describing shows up on a standard measure, and it establishes your baseline — which is what makes a change five years from now easy to see. Many people leave reassured.
IF MORE IS NEEDED
A short set of questions and simple tasks. A few minutes.
Recalling a short list of words. Drawing a clock face. Following a sequence of instructions. Your doctor is looking at memory, attention, language, and problem-solving. There is no needle and no scan, nothing to study for, and no wrong answers. It fits inside a regular visit.
Further work up, and a specialist if needed.
The usual next step is lab work to rule out other causes — thyroid, B12, medication effects. Depending on those results, your doctor may order a blood-based Alzheimer's test or imaging, or refer you to a neurologist, geriatrician, or memory clinic. You and your family are part of every decision.
Questions to ask while you are with your doctor
Can we do a cognitive assessment as part of my visit today?
What can I do right now - lifestyle changes, other conditions to manage?
What did the results show, and what do they mean?
Are there clinical trials I should know about?
Should I see a specialist and how soon?
Who in my family should be part of these conversations?
Should I see a specialist and how soon?
What’s worth mentioning to your doctor
Changes in memory or recall - repeating questions, losing recent conversationsDifficulty with tasks that used to be routine - bills, receipts, a familiar routineLosing the thread in conversations, or trouble finding wordsChanges in mood, motivation, or personality that others have noticedTrouble following plans, instructions, or a sequence of stepsAnything a family member has noticed, even if you haven't
When should we check in again?
THE NEXT STEP
One Sentence is Enough to Start
You don't need the right words, a complete list of symptoms, or any certainty about what's happening. You need one sentence and one appointment.
SAY THIS
“I’ve noticed some changes in my memory, and I’d like to have a cognitive assessment.”
Your doctor takes it from there. If you're asking on behalf of someone else: "I've noticed some changes in my father's memory, and I'd like him to be assessed."
FREQUENTLY ASKED QUESTIONS
The questions people ask the most
Is this just normal aging?
Some forgetfulness is a normal part of getting older. Changes that affect daily life — getting lost on familiar routes, struggling to follow a conversation, repeating the same questions — are worth mentioning to a doctor. Asking isn't assuming the worst; it's finding out which one you're looking at.
Do I need a specialist, or can my primary care do this?
Your primary care doctor can perform an initial cognitive assessment — the most accessible place for this to start. If further evaluation is warranted, they can refer you to a neurologist, geriatrician, or memory clinic.
Is there a blood test for Alzheimer’s now?
There are currently four blood tests that are FDA cleared, and these tools support your doctor’s evaluation. They're used within a clinical evaluation rather than on their own, which is why the conversation with your doctor still comes first. Blood tests are only recommended for individuals with cognitive symptoms, not for those who are cognitively healthy.
What if I’m not ready to know?
That's the most common reason people wait, and it's understandable. What's worth weighing against it: knowing early gives you more options, not fewer, and you set the pace of everything that happens next.
I feel fine. Should I still get my memory checked?
Yes. Cognitive assessment is already a required part of the Medicare Annual Wellness Visit, and having one while you feel well establishes a baseline, which makes any later change far easier to interpret.
I’m worried about someone else. What do I do?
Share what you've specifically noticed, listen without judgment, and encourage a conversation with their doctor. Offer to go with them. You're not delivering a diagnosis — you're helping them reach the person who can answer the question.
What does treatment involve, if it is Alzheimer’s?
Two FDA-approved therapies, lecanemab and donanemab, can slow the progression of early-stage Alzheimer's disease. Both are given by infusion, and lecanemab now as an autoinjector that can be used in the home, both require periodic brain imaging to monitor for side effects, and both are covered by Medicare for people who meet the criteria. Neither is appropriate for everyone, and your physician will discuss the benefits and the risks with you. Treatment also includes managing other conditions that affect cognition, and support for you and your family.
I have a family history of Alzheimer’s. Does that change what I should do?
A family history raises your risk without determining your future. The genes that virtually guarantee Alzheimer's are rare and account for less than one percent of cases; far more common are risk genes such as APOE-e4, which many people carry without ever developing the disease. Tell your doctor about your family history, and discuss any genetic testing with them rather than pursuing it on your own.
