The Silent Loss of a Memory: An Emotional Approach to Dementia and Alzheimer’s
Aunt Ayşe would kiss her grandchild and whisper good wishes every morning before sending her off to school. One morning, when her little granddaughter hugged her, Aunt Ayşe hesitated for a moment in her gaze. That brief hesitation was not just about that single day; it was the first step of a long, slow journey that would begin in Aunt Ayşe’s mind. Dementia often starts this way: a subtle shadow appearing in the eyes of someone we love. Today, we will discuss what that shadow is, what it may bring, and why understanding the difference between dementia and its most commonly confused concept—Alzheimer’s—is so important for all of us.
What is Dementia? A Journey Beyond Forgetfulness
The term "dementia" is much more than a medical diagnosis; it describes a complex and multidimensional picture of brain function loss. Dementia encompasses a group of diseases that impair not only memory, but also thinking, reasoning, understanding, communication, decision-making, and the ability to carry out everyday tasks independently.
It is estimated that approximately 55 million people worldwide live with dementia, and about 10 million new cases are added each year (WHO).
Dementia is not a single disease; it is an umbrella term.
Alzheimer’s disease accounts for 60–80% of all dementia cases.
There are also different types such as vascular dementia, Lewy body dementia, and frontotemporal dementia.
In summary, dementia is a progressive and destructive syndrome resulting from the loss of function of brain cells.
Alzheimer’s: The Most Common Cause of Dementia
Alzheimer’s disease is the most well-known and most common cause of dementia. It was first described in 1906 by German doctor Alois Alzheimer. In Alzheimer’s, "beta-amyloid plaques" and "tau protein tangles" accumulate in the brain. These abnormalities impair communication between neurons, leading to cell death.
Dementia | Alzheimer’s |
|---|---|
A syndrome or group of symptoms | The most common cause of dementia, a specific disease entity |
Has more than one type and cause | Based on specific pathological findings (plaques and tangles) |
Some forms are reversible (e.g., vitamin deficiency dementia) | Alzheimer’s is progressive and cannot be reversed |
The Importance of Dementia and Alzheimer’s in Modern Life
Increased global life expectancy has led to a dramatic rise in cases of dementia, especially Alzheimer’s. By 2050, the number of people with dementia worldwide is expected to reach 139 million (ADI 2021).
As the societal, economic, and individual burdens of dementia increase, it profoundly affects the quality of life for patients and their families. The losses caused by dementia are not just the erasure of old memories; identity, relationships, and independence are also at stake.
Types of Dementia and How Do They Differ from Alzheimer’s?
1. Alzheimer’s Disease
Accounts for 60–80% of all cases.
Has a slow onset and is progressive.
Memory loss is the first and most dominant symptom.
Personality changes, disorientation, and communication difficulties develop over time.
2. Vascular Dementia
Occurs as a result of blockages or hemorrhages in the brain’s blood vessels.
Often marked by sudden onset of forgetfulness and mental changes.
History of stroke is common.
3. Lewy Body Dementia
Characterized by movement issues (Parkinson-like), visual hallucinations, and fluctuating mental clarity.
4. Frontotemporal Dementia
Usually starts before age 60.
Dominated by changes in personality, behavior, and speech.
Other types of dementia also exist. However, Alzheimer’s is often equated with “dementia,” which can lead to confusion.
Primary Symptoms of Dementia
Symptoms of dementia vary by type, but the following main categories predominate in most:
Memory loss: Especially affects short-term memory; the person repeatedly asks the same questions.
Language and speech difficulties: Trouble finding words and forming sentences.
Disorientation: Loss of sense of time and place may occur.
Inability to perform complex tasks: The person struggles with following familiar recipes or doing calculations.
Personality and behavioral changes: Unexplained anger, suspicion, or withdrawal can be seen.
These symptoms progress collectively over years; for a diagnosis of dementia, these changes must significantly impact the person’s daily life.
Key Differences Between Alzheimer’s and Other Types of Dementia
Onset: Alzheimer’s usually starts insidiously, while vascular dementia can have a sudden onset.
First symptoms: Memory loss is dominant in Alzheimer’s, while behavioral or executive dysfunction is more prominent in others.
Course: Alzheimer’s typically progresses slowly and steadily; vascular dementia may advance in steps.
Age: Alzheimer’s mostly affects those over 65, but early-onset forms exist as well.
Recognizing each dementia type’s treatment approach and progression is essential for developing a personalized care plan.
Risk Factors of Dementia: Who is More Vulnerable?
Age: The greatest risk factor. One in ten people over 65 has dementia.
Family history and genetics: Especially significant in early-onset forms.
Chronic diseases: Diabetes, hypertension, high cholesterol, heart and vascular diseases increase the risk.
Lifestyle: Physical inactivity, unhealthy diet, smoking and alcohol use, and social isolation are also risk factors.
Head trauma: Previous brain injuries increase dementia risk.
Diagnosis of Dementia and Alzheimer’s: How Far Has Modern Medicine Come?
The most important step in diagnosing dementia is a detailed neurological and psychiatric assessment based on the patient’s and relatives’ history. This is supported by various neurocognitive tests measuring memory, language, and thinking processes in daily life.
The following methods are used specifically for Alzheimer’s:
Brain magnetic resonance imaging (MRI) or computed tomography (CT)
PET imaging (amyloid/PET and tau/PET-based examinations)
Testing for specific biomarkers in cerebrospinal fluid (CSF)
It is crucial not to miss treatable causes (e.g., vitamin deficiency, thyroid dysfunction). Dementias due to such causes may be reversible with appropriate treatment.
Is There a Cure for Dementia and Alzheimer’s?
Unfortunately, as of today, there is no fully curative treatment for most types of dementia, especially Alzheimer’s. However, many approaches exist to slow disease progression and alleviate symptoms:
Medication: Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) and memantine are used to slow cognitive symptoms.
Lifestyle Modifications: Physical exercise, Mediterranean diet, and engaging in social and cognitive activities.
Supportive Care: Emotional, psychological, and social support for patients and their families can improve quality of life.
Additionally, research is focusing on genes and new biomarkers. More than 100 new drugs are in clinical trials worldwide at present (Source).
Living with Alzheimer’s and Dementia: Difficult but Hopeful Steps Together
Dementia is not simply an individual disease; it is a challenge for entire families and even societies. If your loved one has been diagnosed with dementia or Alzheimer’s, the only challenge is not “forgetting.” Subtle changes in that person’s character, the loss of daily routines, or the disappearance of shared memories may bring about a real mourning process.
"In fact, they are still there, but sometimes finding them requires more patience."
The burden on caregivers is great through this process. Nevertheless, utilizing support groups, professional counseling, and educational resources can help lighten the load.
How Can Dementia and Alzheimer’s Be Prevented? What Does Science Say?
Regular exercise: At least 30 minutes of brisk walking daily positively impacts brain health.
Brain-friendly diet: The Mediterranean diet (olive oil, fish, vegetables, and whole grains) reduces risks.
Social activities: Meeting friends and taking up new hobbies keep the mind alert.
Regular medical check-ups: Blood pressure, diabetes, and cholesterol should be well controlled.
Preventing head trauma: Even a simple fall can have serious consequences, especially for the elderly.
Recent large-scale studies predict that up to 35% of dementia cases could be prevented by modifying risk factors (The Lancet, 2017).
Disease Progression: Stages and Challenges
Across all forms of dementia, progression is typically divided into three stages:
Early stage: Mild difficulties coping with forgetfulness and finding words. The person is generally independent.
Middle stage: Personality and behavioral changes become more pronounced. Assistance is needed with daily activities.
Late stage: Mobility declines; full care is required for nutrition and basic needs.
The pace of progression varies by individual. Some may remain in one stage for a long time, while others progress more rapidly.
Advice and Awareness for Caregivers
Get educated: Understanding dementia and Alzheimer’s makes managing the process easier.
Share your feelings: Open discussion within support circles and family helps lighten the burden.
Be patient: Behavioral problems are a natural result of the disease—do not take them personally.
Take time for yourself: Do not neglect your own well-being while caring for your loved ones.
This process may sometimes feel exhausting and lonely, but with the right support and information, it becomes much more manageable.
Recent Scientific Advances in Approaching Dementia
Important progress is being made in biotechnology. Research is underway on blood, tear, or spinal fluid tests for early diagnosis. Likewise, genetic testing and personalized medicine adapted to lifestyle may radically change disease management in the coming years.
New generation drugs for Alzheimer’s and other dementias are promising in clinical trials. Especially vaccines and antibody-based therapies targeting "amyloid" or "tau" proteins are being intensively researched (Neurology, 2023).
Facing Dementia or Alzheimer’s: Easier with Love and Knowledge
Accompanying someone diagnosed with dementia or Alzheimer’s is a difficult yet deeply instructive journey for understanding how fragile and changeable life is. Infinite patience, love, and understanding, as well as up-to-date and accurate information, are required. Together, the burden of this journey can be lightened.
Ultimately, dementia is not a disease name, but a challenging journey with various causes. Alzheimer’s is the most familiar—but not the only—face of this journey. Knowing the difference is vital for a hopeful and realistic approach.
Brief Frequently Asked Questions
Can dementia be completely reversed? If it is due to certain causes (e.g., vitamin deficiency), yes; but unfortunately, not in progressive types like Alzheimer’s.
Is it possible to live with dementia? With proper care, support, and therapeutic approaches, quality of life can be maximized.
Who is guaranteed to develop Alzheimer’s? Genetic predisposition and older age are key risk factors, but it can potentially affect anyone.
Final Word: Forgetting—A Journey Not Only in Someone’s Memory, But in All Our Hearts
Even though dementia seems like a shadow slowly drifting through a person’s recollections, love and understanding can make this process more meaningful and manageable. The hesitation in Aunt Ayşe’s eyes is not merely a sign of forgetfulness; it is also a call for us to become more conscious and compassionate. Understanding dementia and Alzheimer’s is not just about the loss of a single memory. It is a key to standing by our loved ones and cherishing every moment spent together.
