Do you know the difference between Alzheimer’s disease and dementia? The terms “Alzheimer’s disease” and “dementia” are often used interchangeably, but it is important to know the difference between them. Dementia is not a specific disease, but rather a general term for a set of symptoms caused by physical disorders that affect the brain. Symptoms of dementia include memory loss, language difficulties, impaired problem-solving skills, and other cognitive decline that is severe enough to interfere with a person’s daily life and activities.
Alzheimer’s disease, on the other hand, is a specific disease and the most common type of dementia. It accounts for 60 to 80 per cent of all diagnoses. Alzheimer’s disease results from specific changes in the brain that gradually worsen over time. This leads to changes in the ability to think, remember, reason, and behave, which is why people sometimes refer to it as “dementia.” Other types of dementia include frontotemporal dementia, Lewy body dementia, and vascular dementia.
While everyone experiences changes in brain function as they age, what occurs with Alzheimer’s disease is not a normal part of ageing. Alzheimer’s is a progressive neurodegenerative disease, meaning it worsens over time, and the affected person eventually loses the ability to perform daily tasks. No one knows what causes Alzheimer’s disease. Genes, environment, lifestyle, and overall health may all play a role. Although there is currently no cure for Alzheimer’s, several medications approved by the U.S. Food and Drug Administration (FDA) can help manage some of the disease’s symptoms, along with coping strategies to manage behavioural symptoms.
Is Dementia and Alzheimer’s the Same Thing?
Although they are two distinct concepts, Alzheimer’s and dementia are closely related because Alzheimer’s is the leading cause of dementia. Let’s discuss the main differences between these two concepts and briefly touch upon some types of dementia caused by disorders or diseases other than Alzheimer’s.
Alzheimer’s is a neurodegenerative disease characterised by a slow accumulation of pathological brain changes that gradually alter the functioning of neurons. Alzheimer’s disease is the leading cause of dementia. It has a long preclinical phase, in which, for many years, the neuropathological changes progress without symptoms because the brain has some capacity to compensate for these alterations’ thanks, among other things, to cognitive reserve. However, there comes a point when it can no longer “hide” them, and that is when the signs of cognitive decline begin to appear. Initially, the symptoms are usually related to memory problems, to which other symptoms will be added that, if caused by Alzheimer’s, will eventually lead to dementia.
The difference between Alzheimer’s and dementia lies in the fact that the latter is a set of signs and symptoms caused by brain damage (such as Alzheimer’s) that leads to a loss of cognitive abilities in the affected person. In addition, mood and behavioural changes often appear, and all of this together prevents the person from independently carrying out their daily activities. Therefore, it leads to a loss of autonomy and the consequent dependence on others.
Dementia vs Alzheimer’s: What Makes Them Different?
Alzheimer’s is the main cause of dementia.
Alzheimer’s disease, due to the brain damage it causes, is the main cause of dementia, but it is not the only one. It is estimated that 1 in 10 people over 65 suffers from some type of dementia, and between 60 and 70% of cases are due to Alzheimer’s disease.
The second most frequent cause is related to cerebral vascular disorders, affecting cerebral blood circulation, leading to another type of dementia: vascular dementia. Other neurodegenerative diseases, such as Lewy body dementia, or toxic-metabolic disorders such as those caused by chronic alcoholism, as well as other types of illnesses, can also cause cognitive decline or dementia.
Are all dementias the same?
Having established the difference between Alzheimer’s and dementia, the question arises as to whether all dementias are the same. Although impaired cognitive and behavioural functions characterise all dementias, leading to a loss of independence, depending on the cause and the affected brain areas, certain symptoms will predominate, and the progression will differ.
Alzheimer’s Is a Specific Brain Disease
In the case of Alzheimer’s disease, the first cognitive difficulties are usually reflected in memory loss for recent events. Still, progressively, problems with language, orientation, reasoning, and visual recognition will be added, among others. Other alterations related to perception and other cognitive functions will appear throughout the different stages of the disease.
Behavioural and mood problems will also emerge. All of this will lead to a progressive loss of independence, as it is an irreversible process. Therefore, those affected always end up requiring continuous care, which usually falls to a family member: the primary caregiver.
Not all dementias are caused by Alzheimer’s.
Symptoms They Have in Common
- In Alzheimer’s disease, memory loss is the most characteristic initial symptom, especially the difficulty retaining recent information.
- Temporal and spatial confusion, mood swings, language difficulties,
- In advanced stages, difficulties speaking, swallowing, and walking.
Dementia can present with different symptoms:
- Vascular dementia can appear more suddenly, with symptoms such as confusion, disorientation, and difficulty concentrating.
- Lewy body dementia includes movement problems, daytime hallucinations, and abnormal behaviours during sleep.
- Frontotemporal dementia is characterised by significant personality and behavioural changes from the outset.
Why Understanding the Difference Matters for Families and Carers
Alzheimer’s disease can also affect those who care for patients with this dementia. For this reason, it is crucial to care for the physical and mental health of caregivers of Alzheimer’s patients.
Alzheimer’s disease not only affects the patient who suffers from it, but also their family. Recognising that a loved one is beginning to show signs of this disease is not easy, and caring for them is a significant challenge. It is in this context that a new figure emerges: the caregiver. Although each situation and each Alzheimer’s patient is unique, the caregiver is someone who dedicates most of their time to the patient’s care.
Caring for a person with Alzheimer’s means witnessing their limitations and weaknesses daily as they lose autonomy and become increasingly dependent. This new role carries a cultural and moral responsibility to provide the patient with the best possible care.
Furthermore, it involves both physical and emotional exertion, making it vitally important for the caregiver to take care of themselves in order to be able to provide care. This is because, by focusing attention on the patient, the caregiver’s own health, social life, and interests are often neglected. This can lead to Caregiver Syndrome (or Burnout), defined as a state of exhaustion (physical or emotional) experienced by the person caring for a patient with Alzheimer’s.
This syndrome has a particular pattern, different from that observed in other clinical situations. This is due to the multiple challenges of long-term care imposed by dementia as a disease. Some of these challenges include:
- the duration of the disease process;
- multiple impairments in the cognitive sphere (memory, language, reasoning, and also physical limitations in terms of motor skills);
- the intensity of the care needs;
- unpredictability of behavioural abilities;
- complex feelings of guilt; and
- the challenge of adapting to the continuous changes brought about by the disease.
How the Right Books Can Help Families Understand Dementia
Reading the right books on Alzheimer’s and dementia is an essential tool for both acquiring knowledge and cognitive stimulation throughout life. In the fields of health and research, engaging with books that address topics of interest or concern from a scientific perspective and with diverse viewpoints can contribute to a better understanding of complex concepts, resolve doubts, and raise awareness of realities that affect us directly or indirectly.

- Caregiving for dementia is challenging and demands support.
- Books and resources help families cope and understand the journey.
Conclusion
Is dementia and Alzheimer’s the same thing? Well,Alzheimer’s is a type of dementia, but dementia encompasses all diseases that cause a decline in brain function (also called cognitive function). Indeed, even though our brain ages along with our body, under normal circumstances, this ageing should never prevent us from performing the activities and tasks required for daily life (such as managing our finances, cooking, or driving). It is only when the decline in cognitive function (particularly memory) results in significant difficulties with daily functioning that we speak of dementia. By definition, a person with dementia must therefore have difficulty performing their daily tasks. Dementia becomes increasingly common with age, and up to one in three people may be affected after the age of 85. More recently, dementia has also been called a “major neurocognitive disorder”. Of all the forms of dementia, Alzheimer’s disease is the most common.
For recommended dementia reading Fleeting Moments & Magic Memories exudes realism and authenticity in its portrayal of dementia and Alzheimer’s, which affects not only the diagnosed individual but also their entire support network.
