Every September 21, we observe World Alzheimer's Day, a date that encourages us to talk about a disease that does not discriminate based on age, gender, social status, or place of origin. Behind every diagnosis lies a different story: a father who forgets the way home, a mother who asks the same question over and over, a grandfather who no longer recognizes his grandchildren. And behind every story is a family learning to provide support with patience and love.
In Ecuador, and particularly in Manabí, more and more families are facing this diagnosis without knowing where to turn or what to expect. Often, the early signs are mistaken for normal aging, and the decision to seek help is delayed by months or even years.
In this article, we explain what Alzheimer's is, how it differs from dementia, what signs you shouldn't ignore, what you can do to reduce your risk, and why an early diagnosis can make a real difference in the quality of life for the patient and their family.
What is Alzheimer's? And why is it not the same as dementia?
One of the most commonly misunderstood concepts—even among family members and in some everyday medical conversations—is the difference between Alzheimer's and dementia. Although they are often used interchangeably, they are not the same thing.
- Dementia is a syndrome—that is, a set of symptoms: progressive memory loss, impaired thinking, language difficulties, behavioral changes, and a decline in the ability to perform daily activities.
- Alzheimer's disease is the condition that most commonly causes these symptoms. It is a progressive neurodegenerative condition: over time, neurons deteriorate and lose the ability to communicate with one another, gradually impairing a person's memory, thinking, and independence.
In other words: dementia is how the problem manifests itself; Alzheimer’s is the underlying cause of that manifestation in most cases. According to the World Health Organization (WHO), Alzheimer’s accounts for between 6 and 7 out of every 10 cases of dementia worldwide. The rest are attributed to other causes: vascular dementia (associated with cerebral circulatory problems), Lewy body dementia, frontotemporal dementia, and other less common conditions.
This distinction is not merely academic: it determines the type of tests performed, the treatment approach, and the prognosis. Therefore, when faced with cognitive decline, the medical goal is not only to confirm the presence of dementia but also to identify which disease is causing it.
Important: Occasionally forgetting where you left your keys is not Alzheimer's disease or dementia. The key difference lies in the persistence, frequency, and impact of these lapses on daily life.
Warning signs we shouldn't ignore
Detecting Alzheimer's early can make a big difference in the quality of life for the patient and their family. These are the most common early signs that a doctor looks for:
The Main Warning Signs
- Forgetting information they have just learned or constantly repeating questions. The person asks the same question several times in a single day, without remembering that they have already received the answer.
- Difficulty planning simple tasks or solving everyday problems: following a familiar recipe, managing household finances, or organizing a schedule that used to be a breeze.
- Confusion about time or location: losing track of the day, month, or season; failing to recognize a familiar place; or not remembering how one got there.
- Mood swings, social withdrawal, or loss of interest in usual activities: giving up hobbies, avoiding family gatherings, or displaying irritability for no apparent reason.
- Frequently misplacing objects and being unable to retrace one's steps to find them: putting things in unusual places (keys in the refrigerator, glasses in the pantry) and accusing others of taking them.
- Difficulty following conversations, finding the right words, or repeating the same story during the same conversation.
- Changes in judgment or decision-making: neglecting personal hygiene, making unusual financial decisions, dressing inappropriately for the weather.
When to Seek Help: If someone close to you consistently exhibits several of these signs for weeks or months, it’s best to seek a specialized medical evaluation. This isn’t alarmism—it’s responsibility.
Can Alzheimer's be prevented?
Although there is no foolproof way to prevent Alzheimer's, the scientific evidence is becoming increasingly clear: certain habits help reduce the risk or delay its onset. Brain health is built up over the course of a lifetime, not just in old age.
Habits That Protect Brain Health
- Maintain a socially active life. Human interaction and conversation stimulate areas of the brain that loneliness tends to shut down.
- Monitor your blood pressure and cholesterol. Cardiovascular health is directly linked to brain health. What's good for the heart is good for the brain.
- Get a good night's sleep. During deep sleep, the brain clears away proteins associated with the development of Alzheimer's disease. A restful 7- to 8-hour night's sleep is a concrete preventive measure.
- Eat a balanced diet. The Mediterranean diet—rich in fish, olive oil, vegetables, and nuts—has been shown to have protective effects on cognitive function.
- Engage in regular physical exercise. At least 150 minutes of moderate-intensity activity per week improves blood flow to the brain and stimulates the formation of new neural connections.
- Keep your mind active: reading, strategy games, learning a new language, playing a musical instrument, or any activity that requires sustained cognitive effort.
- Avoid smoking and excessive alcohol consumption, both of which are associated with an increased risk of cognitive decline.
In short, taking care of your brain begins long before the first symptoms appear.
The Value of a Timely Diagnosis
It takes many families months, even years, to seek help because they mistake the symptoms for normal aging. “He’s just getting older,” “We all forget things,” “Don’t make a big deal out of it.” These comments, though well-intentioned, can delay a diagnosis that changes everything.
Early diagnosis allows for:
- Start treatments that slow the progression of the disease. Although there is no cure for Alzheimer's, there are medications that can significantly delay the progression of symptoms when started in the early stages.
- Rule out other treatable causes of memory loss. Certain conditions, such as vitamin deficiencies, thyroid problems, depression, or side effects of medications, can mimic the symptoms of Alzheimer's and are completely reversible.
- Plan for long-term care. Make legal, family, and financial decisions while the person still has the capacity to express their opinions and make decisions.
- Prepare the family. Learn how to provide support, find support networks, adapt the home, and organize responsibilities among caregivers.
- To provide greater peace of mind to both the patient and their loved ones.
Which specialist should you see? An approach that is no longer limited to neurologists
For years, the diagnosis of Alzheimer's disease was associated solely with neurology. Today, clinical practice is broader and more collaborative: various specialists can serve as the appropriate point of entry, and which one is most suitable depends on the timing, the patient's age, and any accompanying conditions.
Family Medicine: The First Point of Contact
The family physician is usually the one who has known the patient for years and is, very often, the first to detect subtle changes during routine checkups. He or she can perform an initial cognitive assessment, rule out reversible causes with basic tests, and coordinate a timely referral when necessary.
Consulting with a family medicine physician is an excellent starting point, especially when the patient already has a trusted primary care physician.
Geriatrics: Comprehensive Care for Older Adults
A geriatrician is a specialist in the health of older adults, and in current clinical practice, plays a central role in the management of Alzheimer’s disease. Their approach goes beyond the disease itself: it considers the patient as a whole.
This is particularly valuable because Alzheimer’s rarely occurs on its own. It often coexists with high blood pressure, diabetes, polypharmacy, a risk of falls, nutritional problems, or depression. The geriatrician manages all of these conditions in a coordinated manner, avoiding conflicting treatments and prioritizing quality of life.
In many cases, the geriatrician provides long-term care for patients with Alzheimer's disease, in coordination with the family.
Neurology: Differential Diagnosis and Complex Cases
A neurologist is typically consulted when the following is required:
- Complex differential diagnosis (to distinguish Alzheimer's disease from other causes of dementia).
- Cases of early-onset (before age 65).
- Atypical or unusually progressive cases.
- Interpretation of advanced imaging studies and specific neurological tests.
An approach that builds on, rather than competes with
For a patient with Alzheimer’s, the ideal approach is not to choose “one specialty or the other,” but rather to build a medical team that works in coordination. Family medicine, geriatrics, and neurology can complement one another throughout the process, with each discipline contributing its expertise at the appropriate time. In addition, when the case warrants it, geriatric psychiatry, nutrition, physical therapy, and social work may also be involved.
The most important thing is not to put off your first appointment. Any of these specialists can get the process started.

Frequently Asked Questions About Alzheimer's Disease
What is the difference between Alzheimer's disease and dementia? Dementia is a syndrome—that is, a set of symptoms (memory loss, impaired thinking, behavioral changes) that interfere with daily life. Alzheimer’s disease is the most common cause of these symptoms: it accounts for 6 to 7 out of every 10 cases of dementia. Other causes include vascular dementia, Lewy body dementia, and frontotemporal dementia.
At what age can Alzheimer's disease develop? Although it is more common after age 65, there is a form known as early-onset Alzheimer's, which can develop as early as age 40 or 50. Early-onset Alzheimer's typically has a stronger genetic component.
Which specialist should I see first? There is no single correct answer. A family physician is an excellent first point of contact, especially if they already know the patient. A geriatrician is particularly well-suited for older adults with multiple health conditions. A neurologist is especially helpful in cases of complex differential diagnosis or early-onset conditions. The important thing is not to delay the consultation: any of these specialists can get the process started.
Does frequent forgetfulness always mean Alzheimer's? No. Many conditions can cause forgetfulness: stress, anxiety, depression, lack of sleep, vitamin B12 deficiency, thyroid problems, or side effects from medications. That is why a medical evaluation is so important: to distinguish between benign forgetfulness, reversible causes, and a possible onset of cognitive decline.
Is Alzheimer's hereditary? In most cases, Alzheimer's is not hereditary in the strict sense, but there are genetic factors that increase the risk. Having an immediate family member with Alzheimer's increases the likelihood, though it does not determine it. Lifestyle habits continue to play a significant role.
What tests are used to diagnose Alzheimer's disease? The diagnosis includes a clinical evaluation by a doctor, cognitive tests (memory, attention, language), blood tests to rule out other causes, and brain imaging studies such as MRI or CT scans. In some cases, more specific tests are performed.
When should I take my family member to the doctor? When warning signs—persistent forgetfulness, confusion, behavioral changes—appear repeatedly over several weeks and begin to affect their daily activities. Don’t wait until the situation is obvious to everyone: the sooner you seek medical advice, the more treatment options are available.
