Dementia and Alzheimer’s: What is the Difference?

Medically reviewed by Sandeep Dhanyamraju
Medically reviewed by Sandeep Dhanyamraju

Many people mistakenly confuse dementia and Alzheimer’s, thinking they are the same thing but are not.  Among the main differences between these conditions, experts note that, unlike dementia, in Alzheimer’s disease, symptoms begin slowly and develop gradually, memory loss is the main consequence of this disease, and the life expectancy of a patient with this disease is higher. The word “dementia” is used to describe a group of symptoms that can have many causes. The symptoms of dementia are mainly memory loss and problems with routine activities and communication with others.

Both of these problems most often occur in patients over 65, but they can occur at any age. Although the symptoms of these conditions can coincide, it is necessary to be able to distinguish between these conditions.

In this article, we will look at the description of these two problems, consider their causes and symptoms, and also find out if there is a difference between dementia and Alzheimer’s disease.

What is Dementia?

Dementia is not a disease. This is one of the reasons why Alzheimer’s disease and dementia are not the same. Dementia is a syndrome, a set of symptoms with no specific diagnosis. Dementia most often occurs in people with Alzheimer’s disease. Dementia harms many cognitive functions such as memory and thinking.

What is Dementia

Dementia comes in many types; some patients may have more than one type of dementia. Unfortunately, dementia has the property of progression; if this occurs, the patient’s condition may worsen and lead to disability. In addition, according to statistics, dementia ranks fifth on the list of diseases that cause death in humans.

What are the Types of Dementia?

One of the reasons why Alzheimer’s disease and dementia are not the same conditions is the existence of different types of them. 

As we have said, there are different types of dementia. Let’s look at the types of this syndrome in more detail.

  • Vascular Dementia

This type of dementia usually occurs due to blockage of blood flow to a person’s brain and may be associated with strokes or plaque in the arteries. Symptoms of the disease can begin slowly and quite suddenly.

  • Dementia with Lewy Bodies

This dementia is a progressive disease. It can be caused by protein deposition in the nerves, disrupting electrical signals. Symptoms of this type of dementia include changes in thinking, confusion, and movement disorders.

  • Dementia Associated with Parkinson’s Disease

This dementia causes deterioration in cognitive abilities and we have to say that Alzheimer’s disease also has this problem, so it can be the same thing between them. This syndrome often occurs in people with Parkinson’s disease about a year or more after being diagnosed. Analyzing statistics, 50-80% of people with Parkinson’s disease suffer from dementia ten years after diagnosis. 

  • Frontotemporal Dementia

This syndrome is characterized by brain dysfunction in the area of ​​the brain near the forehead or behind the ears. The Alzheimer’s Association suggests that behavioral changes are often among the first symptoms of frontotemporal dementia.

  • Posterior Cortical Atrophy

It is the deterioration of the outer layer of the patient’s brain, which is called the cortex and is located at the back of the brain. Symptoms of this type of dementia can vary but usually involve difficulty with visual tasks such as reading or seeing moving objects.

  • Creutzfeldt-Jakob Disease

It is a relatively rare infectious disease. This disease causes a rapidly progressive dementia that begins with symptoms such as problems with muscle coordination, personality changes, and visual disturbances.

  • Wernicke-Korsakoff Syndrome

This syndrome occurs against the background of a lack of vitamin B1 in the body. One of the most common causes of this syndrome is alcoholism. Among the symptoms of this syndrome, experts note double vision, confusion, drooping of the upper eyelids, and loss of muscle coordination. The presence of such symptoms once again confirms that Alzheimer’s disease and dementia are not the same conditions.

  • Mixed Dementia

This type of dementia means that the patient has several types of dementia.

  • Normal-pressure Hydrocephalus

This syndrome occurs due to the accumulation of fluid in the ventricles of the patient’s brain. Among the consequences of the appearance of this syndrome, one can note an impairment of consciousness and difficulties associated with the movement and control of the bladder. The exact cause of this condition is not known, but suspected causes include head injuries, infections, cerebral hemorrhages, and previous surgeries.

  • Huntington’s Disease

It is a rare disease that destroys nerve cells in the brain. The cause of this syndrome is a gene anomaly. One of the first symptoms may be apathy, psychosis, and incoordination.

Symptoms of Dementia

Symptoms of dementia

When we talk about what the difference between dementia and Alzheimer’s disease is, we should say that these conditions have different symptoms. For example, dementia can be accompanied by the following symptoms:

  • Memory loss;
  • Difficulty with verbal expression;
  • Personality changes;
  • Hallucinations;
  • Poor orientation in space and time;
  • Frequent forgetfulness;
  • Lack of necessary hygiene;
  • Depression;
  • Aggression.

Causes of Dementia

Experts note the following reasons why dementia can occur:

  • Chronic drug use;
  • Stroke;
  • Vascular disease;
  • Infections such as HIV;
  • Vascular diseases;
  • Head trauma;
  • Depression.

How to prevent or slow down Dementia with diet and brain foods find out from our article.

What is Alzheimer’s Disease?

We have told you there is a difference between dementia and Alzheimer’s disease and that these conditions are not the same. But to finally show you the difference between them, we should consider Alzheimer’s disease in more detail.

Alzheimer’s is a brain disease that tends to progress and progressively impair memory and cognitive function. The specific cause of the disease is still unknown, and there is no cure for this disease. Alzheimer’s disease usually affects people over 65, but sometimes younger people get the disease.

What is alzheimers disease

How Alzheimer’s Disease Affects the Brain

Another factor that confirms that dementia and Alzheimer’s disease are not the same thing is the effect of the condition on the brain. Let’s consider how Alzheimer’s disease affects the brain.

In people who have Alzheimer’s disease, brain cells gradually die off, and the connections between the remaining cells are significantly destroyed.

  • One of the main symptoms is the accumulation of plaques – abnormal protein deposits that appear in the brain. These protein deposits look like dense protein clusters. They can block communication between neurons. Proteins twisting together are called tangles and cause healthy brain cells to begin to die.
  • The brain begins to contract strongly in a person with Alzheimer’s. The development of the disorder in the brain can occur over decades.
  • The only way to confirm the presence of the disease is to examine the patient’s brain under a microscope. However, doctors have learned to correctly diagnose this in 90% of cases with regards to this disease.

Symptoms of Alzheimer’s Disease 

Symptoms of Alzheimers Disease

Actually, symptoms of Alzheimer‘s disease and dementia are also not the same.

Alzheimer’s may include symptoms such as:

  • Mood changes;
  • Depression;
  • Confusion;
  • Concentrating difficulty;
  • Apathy;
  • Impaired judgment;
  • Disorientation;
  • Behavioral changes;
  • Problems with speech;
  • Difficulty swallowing;
  • Violation of movement coordination.

Causes of  Alzheimer’s 

  • Genetic predisposition;
  • Diabetes;
  • Chronic hypertension;
  • High cholesterol;
  • Traumatic brain injury.

Alzheimer’s vs. Dementia: Comparison Table 

We have prepared a comparative table in which we have seen what the difference between dementia and Alzheimer’s disease is so that our readers can better understand the main differences between these conditions.

Alzheimer’s Dementia
It is a disease It is a syndrome (complex of symptoms)
Has no official causes Has specific causes
The absence of symptoms that include an increase in muscle tone and sleep disturbance, at least at an early stage of this disease  Symptoms of this syndrome include an increase in muscle tone and insomnia
This disease primarily affects short-term memory This syndrome has speech disorders, emotional disorders, and difficulties in planning and solving problems 
It develops rather slowly – the process of disease development can take several years The deterioration comes suddenly and more abruptly
Probable causes can be connected with a hereditary predisposition and neurological diseases The causes of the appearance are vascular pathologies
Memory loss is gradual Memory loss occurs suddenly and can rapidly develop quite quickly and jerkily (it’s one of the main reason why Alzheimer’s disease and dementia are not the same things)
Life expectancy is longer The life expectancy of a patient with this syndrome may be lower
Women are more likely to suffer from this  disease Men are more likely to suffer from dementia

You can read about life expectancy for Alzheimer’s Disease & Dementia in our blog.

So, you can see what the main differences between dementia and Alzheimer’s disease are. Doctors say that not every dementia is associated with Alzheimer’s disease, but every Alzheimer’s disease ends in dementia. 

Regarding such a question as “Which is worse, dementia or Alzheimer’s disease?, we should say that these two conditions are hazardous for the patient. But as a rule, dementia is a more complex problem because it can happen unexpectedly out of the blue. The patient’s condition can be severe immediately, and the syndrome’s symptoms can worsen quickly. Also, as you can see from the table, dementia patients live much shorter lives.

Just such an amazing staff that makes you feel like part of their family. I’ve been going there for over 5 years now... and each visit I get the very best care and treatments that I have ever received in the 20+ years that I’ve been dealing with severe debilitating migraines. Since i started seeing them the number of my migraines has dropped from 15-20 a month to 2-3 every 3 month. I highly recommend them …they will change your life!read more

Dr. Askari was very kind and explained everything so I could understand. The other staff were nice as well. I would... have gave 5 stars but I was a little taken aback when I checked in and had to pay 600.00 upfront. I think that should have been discussed in a appointment confirmation call or email just so I could have been prepared.read more

I was obviously stressed, needing to see a neurologist. The staff was so patient and Dr. Ansari was so kind. At one... point he told me to relax, we have time, when I was relaying my history of my condition. That helped ease my stress. I have seen 3 other neurologists and he was the only one who performed any assessment tests on my cognitive and physical skills. At one point I couldn't complete two assessments and got upset and cried. I was told, it's OK. That's why you're here. I was truly impressed, and super pleased with the whole experience!read more

Since my first post my thoughts have changed here. It's unfortunate. My doctor and PA were great, but the office staff... is horrible. They never call you back when they say they will, they misinform you, they cause you too much stress wondering what's going on, they don't keep you posted. They never answer the phone. At this point I've left four messages in the last week, and I have sent three messages. Twice from their portal and one direct email. No response. My appointment is on Monday morning at 8:30am, no confirmation on my insurance and what's going on. What the heck is going on, this is ridiculous!I've given up... the stress her office staff has put me through is just not worth it. You can do so much better, please clean house, either change out your office staff, or find a way for them to be more efficient please. You have to do something. This is not how you want to run your practice. It leaves a very bad impression on your business.read more

Had very positive appointments with Jodie and Dr. Sheth for my migraine care. Jodie was so fast with the injections and... has so much valuable info. I started to feel light headed during checkout and the staff was SO helpful—giving me a chair, water, and taking me into a private room until I felt better. Highly recommend this practice for migraine patients, they know what they’re doing!!read more

I had such a good experience with Lone Star Neurology, Brent my MRI Tech was so awesome and made sure I was very... comfortable during the appointment. He gave me ear plugs, a pillow, leg support and blanket, easiest MRI ever lol 🤣 My 72 hour EEG nurse Amanda was also so awesome. She made sure I was take care of over the 3 days and took her time with the electrodes to make sure it was comfortable for me! Paige was also a huge help in answering all my questions when it came to my test results, and letting me know her honest opinions about how I should go forth with my treatment.read more

I love going to this office. The staff is friendly and helpful. The doctor is great. I am getting the best... neurological tests and treatment I have ever had. The only reason I did not give them a 5 star rating is because it is impossible to reach a live person at the office to reschedule appointments. Every time I have tried to get through to the office it says all people are busy and I am sent to a voicemail. If they could get their phone answering fixed, I would give them a strong 5 stars.read more

Let me start by saying that I have been coming here for years. Due to my autoimmune disease, I am in this office... once every three weeks for multiple hours at a time. The office is very clean and the staff very friendly. My only complaint would be there communication via phone. They aren't the best at responding if you leave a voicemail and expect a call back. I understand that this is prob just due to the sheer number of alls they receive daily. What I can say I like the best about the office are the people. Bobby who handles my infusions is great. I never have any issues with her setting up my infusions. She is very quick to reply to messages sent via text and if she were to leave then my whole opinion of the office may change. I also enjoy people like Matt, Lauren, and Jodi. I appreciate all that they do for me and without this team I'm not sure I would be as happy as I am to visit the office as frequently as I have to. Please ensure that these folks are recognized as they are what makes my visit to this office so tolerable :).read more
