Variables Impacting Life Expectancy Calculations
Gender. Men dont live as long with Alzheimers as women. A study of more than 500 people diagnosed with Alzheimers disease between 1987 and 1996 found that women with Alzheimers live, on average, 20% longer than men. Age. Someone diagnosed at 65 lives an average of about eight years, while someone over 90 who gets a diagnosis typically lives about three-and-a-half more years. Strength of Symptoms at Diagnosis. If someone is showing especially severe dementia-related problems at the time of diagnosis, this usually leads to an earlier death. Someone who wanders, is prone to falling, and experiences urinary incontinence , will typically not live as long. A lower mini-mental state examination score at the time of diagnosis will also not live as long. Other Health Problems. A person with a history of heart problems or asthma or diabetes, for example, will not live as long as someone without those underlying issues.
What Age Does Dementia Start
Typically, dementia symptoms occur after age 65, and the risk of dementia increases with age. Though rare, even people in their 30s can start showing signs of Alzheimers, according to the National Institute on Aging. The age when someone can get dementia also varies depending on the type theyre experiencing.
Here are the age ranges of when some common forms of dementia are typically diagnosed.
- Alzheimers disease: Mid-60s
- Frontotemporal dementia: Between 45 and 64
- Lewy body dementia: After age 50
- Vascular dementia: Over age 65
If someone gets Alzheimers before their mid-60s, its considered to be early-onset dementia. The signs of early-onset dementia are similar to typical symptoms of dementia.
Signs Of Mild Alzheimers Disease
In mild Alzheimers disease, a person may seem to be healthy but has more and more trouble making sense of the world around him or her. The realization that something is wrong often comes gradually to the person and his or her family. Problems can include:
- Poor judgment leading to bad decisions
- Loss of spontaneity and sense of initiative
- Taking longer to complete normal daily tasks
- Repeating questions
- Increased sleeping
- Loss of bowel and bladder control
A common cause of death for people with Alzheimers disease is aspiration pneumonia. This type of pneumonia develops when a person cannot swallow properly and takes food or liquids into the lungs instead of air.
There is currently no cure for Alzheimers, though there are medicines that can treat the symptoms of the disease.

Changes In Behaviour Judgement And Moods
Becoming quiet, withdrawn or restless or frustrated or angry can be early signs of dementia. Someone may develop repetitive behaviour for example, they ask the same question over and over again, do the same thing repeatedly or make multiple phone calls to the same person. They may become insecure and anxious or start hiding and losing items. They may withdraw from social activities or give up hobbies and interests they have enjoyed.
They may show poor judgement, for example putting summer clothes on in cold winter months, not knowing when a kettle is full or overfilling cups when making cold and hot drinks, putting a kettle on the hob or leaving a cooker on or tap running. Someone with dementia may become very emotional and experience rapid mood swings or become quieter and less emotional than usual.
Talking With A Doctor
After considering the persons symptoms and ordering screening tests, the doctor may offer a preliminary diagnosis or refer the person to a Cognitive Dementia and Memory Service clinic, neurologist, geriatrician or psychiatrist.Some people may be resistant to the idea of visiting a doctor. In some cases, people do not realise, or else they deny, that there is anything wrong with them. This can be due to the brain changes of dementia that interfere with the ability to recognise or appreciate the changes occurring. Others have an insight of the changes, but may be afraid of having their fears confirmed.One of the most effective ways to overcome this problem is to find another reason for a visit to the doctor. Perhaps suggest a check-up for a symptom that the person is willing to acknowledge, such as blood pressure, or suggest a review of a long-term condition or medication.Another way is to suggest that it is time for both of you to have a physical check-up. Any expressed anxiety by the person is an excellent opportunity to suggest a visit to the doctor. Be sure to provide a lot of reassurance. A calm, caring attitude at this time can help overcome the person’s very real worries and fears.Sometimes, your friend or family member may refuse to visit the doctor to ask about their symptoms. You can take a number of actions to get support including:
- talking with other carers who may have had to deal with similar situations

There are many signs that can tell you death is near for a dementia payment. Even though you may be prepared for the end, it is never easy. The ten signs that death is near include:
How Quickly Does Dementia Progress
The speed at which dementia progresses varies a lot from person to person because of factors such as:
- the type of dementia for example, Alzheimers disease tends to progress more slowly than the other types
- a persons age for example, Alzheimers disease generally progresses more slowly in older people than in younger people
- other long-term health problems dementia tends to progress more quickly if the person is living with other conditions, such as heart disease, diabetes or high blood pressure, particularly if these are not well-managed
- delirium a medical condition that starts suddenly .
There is no way to be sure how quickly a persons dementia will progress. Some people with dementia will need support very soon after their diagnosis. In contrast, others will stay independent for several years.

What Are The Early Signs Of Dementia In Women And Men
Generally, the most common early signs of dementia in men and women are similar. They may include typical symptoms like short-term memory loss, lack of concentration, and difficulty with familiar tasks.
Some types of dementia affect women more often than men and vice versa. Among the common types of dementia, men appear to be more likely than women to have Lewy body dementia and vascular dementia, according to a research review in Dialogues in Clinical Neuroscience.
However, women are twice as likely to get Alzheimers, the leading cause of dementia. The fact that women simply live longer than men is a main reason theyre more likely to develop Alzheimers. But researchers are also exploring other possible links between sex and gender and the risk of Alzheimers.
Meanwhile, men and women are at equal risk of developing frontotemporal dementia, according to Johns Hopkins Medicine.
Lastly, men and women can have different symptoms depending on the type of dementia. For instance, women with Alzheimers tend to experience depression more, while men are more likely to experience agitation, according to a research review in Psychiatric Times.
Dementia Symptoms To Watch For
Here are some of the warning signs identified by dementia experts and mental health organizations:
Difficulty with everyday tasks. Everyone makes mistakes, but people with dementia may find it increasingly difficult to do things like keep track of monthly bills or follow a recipe while cooking, the Alzheimers Association says. They also may find it hard to concentrate on tasks, take much longer to do them or have trouble finishing them.
Repetition. Asking a question over and over or telling the same story about a recent event multiple times are common indicators of mild or moderate Alzheimer’s, according to the Cleveland Clinic.
Communication problems. Observe if a loved one has trouble joining in conversations or following along with them, stops abruptly in the middle of a thought or struggles to think of words or the name of objects.
Getting lost. People with dementia may have difficulty with visual and spatial abilities. That can manifest itself in problems like getting lost while driving, according to the Mayo Clinic.
Personality changes. A loved one who begins acting unusually anxious, confused, fearful or suspicious becomes upset easily or loses interest in activities and seems depressed is cause for concern.
Troubling behavior. If your family member seems to have increasingly poor judgment when handling money or neglects grooming and cleanliness, pay attention.
People with mild cognitive impairment are at an increased risk of developing dementia.

Although There Is No Cure For Dementia Yet Scientists And Researchers Are Working Hard To Find One
Support and treatments are available to allow people with dementia to lead active lives and carry on doing the things that matter to them most.
There are medicines for some types of dementia that can ease symptoms for a while, or slow down their progression, in some people.
Other non-drug approaches that can help with symptoms of dementia include:
- cognitive stimulation, which might involve doing word puzzles or discussing current affairs
- life story work, sharing memories and experiences with a carer or nurse to create a life story book
- keeping as active as possible physically, mentally and socially which can boost memory and self esteem, and help avoid depression.
How To Understand The Difference And Why It Matters

Doctors usually rely on observation and ruling out other factors to diagnose Alzheimer’s.
En español | The terms dementia and Alzheimers have been around for more than a century, which means people have likely been mixing them up for that long, too. But knowing the difference is important. In the simplest terms, one is broader than the other. If the two were nesting dolls, Alzheimers would fit inside dementia, but not the other way around. While Alzheimers disease is the most common form of dementia , there are several other types. The second most common form, vascular dementia, has a very different cause namely, high blood pressure. Other types of dementia include alcohol-related dementia, Parkinsons dementia and frontotemporal dementia each has different causes as well. In addition, certain medical conditions can cause serious memory problems that resemble dementia.
A correct diagnosis means the right medicines, remedies and support. For example, knowing that you have Alzheimers instead of another type of dementia might lead to a prescription for a cognition-enhancing drug instead of an antidepressant. Finally, you may be eligible to participate in a clinical trial for Alzheimers if youve been specifically diagnosed with the disease.

Women Might Be At Higher Risk
Age is the major risk factor for Alzheimers disease, and women on average live longer than men.
However, longevity alone does not fully explain why two-thirds of Alzheimers patients are women. Even after taking into account the difference in longevity, some studies have suggested that women are still at a higher risk.
How Long Will A Person With Dementia Live For
Dementia is a life-limiting condition, but it is very difficult to know how long someone with dementia will live for. This depends on many factors.
If the person also has another life-limiting condition , it may be clearer how long they may live for and how they will die.
A person may die from another condition at any stage of having dementia. Because of this, they may die before their dementia symptoms become very advanced.
A person in the later stages of dementia may get worse slowly over many months. During this time they will usually:
- become more frail
- have more frequent falls or infections
- have problems eating, drinking and swallowing
- be more likely to need urgent medical care
- become less mobile
- talk less often.
A person in the later stages of dementia is likely to have a weak immune system. This means they have a higher risk of getting infections, which in some cases can last for a long time. One of the most common causes of death for people with dementia is pneumonia caused by an infection.
A person in the later stages of dementia may have symptoms that suggest that they are close to death, but can sometimes live with these symptoms for many months. This uncertainty makes it very difficult to plan and put things in place for the end of someones life.

How To Talk To Someone You Think Has Signs Of Dementia
Talking about memory loss, and the possibility of dementia, can be difficult. Someone who is experiencing these symptoms may be confused, unaware they have any problems, worried, or struggling to accept their condition.
Before starting a conversation with someone you’re concerned about, the Alzheimer’s Society suggests you ask yourself:
- has the person noticed their symptoms?
- do they think their problems are just a natural part of ageing?
- are they scared about what their symptoms could mean for their future?
- do they think there will not be any point in seeking help?
- are you the best person to talk to them about memory problems?
When you do talk to them, choose a place that is familiar and not threatening. Also, allow plenty of time so the conversation is not rushed.
The Alzheimer’s Society has more tips on how to talk to someone about memory problems.
If the person does not want to see a GP, many UK dementia charities offer support and advice from specialist nurses or advisers, such as:
- Alzheimer’s Society’s national helpline: or email:
How To Test For Dementia
There is no single test that can determine a person is suffering from dementia. The doctor can diagnose different types of dementia such as Alzheimers based on their medical history.
This has to be done very carefully. In addition, the doctor may conduct laboratory tests, physical examinations, and changes in the way the patient thinks.
When all things are considered carefully, a doctor can be able to determine that a person is actually suffering from dementia with certainty. Determining the type of dementia can be hard, especially due to the fact that brain changes and symptoms that are associated with the different types of dementias sometimes overlap.
It is normal for the doctor to give a diagnosis of dementia without really specifying the type. In such a case, it is important for the patient to visit a specialist in this area like a psychologist or neurologist for a more specific diagnosis.

Signs Of Death In Elderly With Dementia: End Stage
Dementia is a term used to describe the persistent or chronic decline in ones mental processes and this include personality changes, impaired reasoning, and memory loss. The most common form is Alzheimers disease and it accounts for over 70 percent of all the dementia cases.
It is one of the greatest causes of death in the United States with over five million people living with the disease in the country alone. One of the age groups affected by dementia is the seniors. If you are a caregiver, it is important to know the signs of death in elderly with dementia.
Most progressive dementias and Alzheimers disease do not have any cure. The diseases get worse with the passage of time, but the timeline can be very different from one person to the next.
Caring for persons with the diseases can be stressful and very challenging, especially when their personality begins to change and their cognitive function starts to decline. It is possible that the individual will not even recognize the people who are closest and dearest to them.
As the disease progresses, the person needs more and more support from the caregiver and the family. If the person is elderly, the caregiver needs to know about all the signs that the patient may be dying.
You may need to put the patient on hospice so as that he or she can get the appropriate care during such moments. This offers the family and the patient spiritual, physical, and emotional care.

Put Systems Into Place Early On In The Diagnosis
It doesnt get any easier to have awkward discussions as time goes on. Because this is a condition that worsens over time, we should get this conversation started as soon as possible before the symptoms get more severe.
Even if a person has Alzheimers disease and is already in its early stages, they might still be able to communicate their preferences and have some say in how they will be cared for in the future.
Almost everyone wishes theyd started sooner rather than later. But again, breaking the news of a diagnosis really does depend on the person and family members involved.
There is currently no treatment that may cure dementia or slow down the diseases progression. But, certain medications can assist in reducing the severity of the diseases symptoms for a short period of time.
