Dementia vs Alzheimer’s is one of the most commonly searched questions families face when a loved one begins showing signs of memory loss. The two terms come up together constantly, but when it comes to dementia vs Alzheimer’s, they actually mean very different things. With World Alzheimer’s Day on September 21st, there is no better time to clear up the confusion.
At Ridgeview Health Center in San Diego, our team supports individuals living with Alzheimer’s disease and other forms of dementia every day through personalized memory care, structured routines, and compassionate attention. We hope this guide helps families feel a little more informed and a little less overwhelmed.
What Is Dementia?
When families start researching dementia vs Alzheimer’s, this is usually where the confusion begins. Here is the simplest way to think about it: dementia is not a disease. It is an umbrella term that describes a collection of symptoms serious enough to interfere with daily life (Mayo Clinic, 2024). Think of it the way you would think of the word “fever.” A fever is a symptom, not a diagnosis. Dementia works the same way.
Those symptoms can include:
- Decline in memory
- Problems with reasoning
- Decline in thinking skills
- Decreased focus and attention
- Changes in language and/or behavior
Dementia is caused by damage to brain cells that affects their ability to communicate, which in turn can affect thinking, behavior, and feelings (Alzheimer’s Association, n.d.). It can be a symptom of several different diseases, including Alzheimer’s, Parkinson’s, Huntington’s, and Creutzfeldt-Jakob disease, among others.
What Is Alzheimer’s Disease?
The other half of the dementia vs Alzheimer’s conversation is Alzheimer’s disease itself. Alzheimer’s disease is a specific brain disease, not a general term. It is degenerative, meaning it gets worse over time, and it is caused by complex changes in the brain following cell damage (Mayo Clinic, 2024).
One of the earliest and most recognizable signs of Alzheimer’s is trouble remembering new information. That is because the disease typically affects the part of the brain associated with learning first. Over time, as Alzheimer’s progresses, symptoms become more advanced and can include:
- Dementia
- Difficulty speaking
- Difficulty swallowing
- Walking impairment
It is worth noting that while most people with Alzheimer’s are 65 and older, the disease is not a normal part of aging. Approximately 200,000 Americans under the age of 65 are currently living with younger-onset Alzheimer’s disease (Alzheimer’s Association, n.d.).
Key Similarities Between Dementia vs Alzheimer’s
Even though dementia vs Alzheimer’s represent different things, there is understandable overlap. Here is what the two have in common:
Both involve cognitive decline that affects daily life. Both can cause changes in memory, thinking, and behavior. And importantly, neither is a normal part of getting older. This is one of the most important things for families to understand. Memory changes that significantly interfere with everyday activities are worth talking to a doctor about, regardless of what is causing them.
Alzheimer’s Is the Most Common Cause of Dementia
One of the reasons dementia vs Alzheimer’s gets so confusing is that Alzheimer’s disease accounts for 60 to 80 percent of all dementia cases (Alzheimer’s Association, n.d.). So when someone receives a dementia diagnosis, there is a good chance Alzheimer’s is the underlying cause. But not always. Other conditions such as Lewy body dementia, vascular dementia, and frontotemporal dementia can also cause dementia symptoms, which is why an accurate diagnosis matters.
When to Seek Help
Whether you are sorting through dementia vs Alzheimer’s or simply noticing changes in a loved one’s memory, thinking, or behavior, the most important thing you can do is talk to their doctor. Early diagnosis opens the door to more options, more time for planning, and better support for the whole family.
Some signs worth bringing up with a medical professional include repeated questions, getting lost in familiar places, difficulty managing everyday tasks, and noticeable changes in personality or mood. These do not automatically mean Alzheimer’s or another form of dementia, but they are worth taking seriously.

Is dementia a normal part of aging?
No. While some minor changes in memory are normal as we age, dementia is not. It is caused by specific diseases that damage brain cells and is always worth discussing with a doctor.
When should I talk to a doctor about a loved one's memory?
