Failing To Pick Up On Sarcasm And Spot A Liar
You may or may not appreciate a sarcastic sense of humor, but sarcasm is a part of our culture. “We see it as a nice way to be critical, and so we use it constantly, even when we are trying to be nice,” says Rankin, whose research found that people with both frontotemporal dementia and Alzheimer’s disease tend to have a harder time picking up on sarcasm.
Another unusual sign of dementia that Rankin noticed? People with FTD couldn’t tell when someone was lying, although people with Alzheimer’s disease could tell. “FTD patients don’t have that sense anymore that things that people do could turn out badly,” she says.

Dementia is the term given to a group of diseases that affect a persons thinking, behaviour and ability to perform everyday tasks. While its commonly thought of as an older persons disease, dementia can affect people of all ages.
Early symptoms of dementia can be vague and vary between people. While some people pick up on changes in their own thinking or behaviour that might be caused by dementia, sometimes these signs are first noticed by those around them.
If youve noticed a change in someone close to you, the steps below can help you assist them in seeking diagnosis and treatment.
What Happens In Alzheimer Disease
You probably know that your brain works by sending signals. Chemical messengers, called neurotransmitters , allow brain cells to talk to each other. But a person with Alzheimer disease has lower amounts of neurotransmitters.
People with Alzheimer disease also develop deposits of stuff that prevent the cells from working properly. When this happens, the cells can’t send the right signals to other parts of the brain. Over time, brain cells affected by Alzheimer disease also begin to shrink and die.

What Are The Benefits Of An Early Alzheimer’s Diagnosis
Alzheimers disease slowly worsens over time. People living with this disease progress at different rates, from mild Alzheimers, when they first notice symptoms, to severe, when they are completely dependent on others for care.
Early, accurate diagnosis is beneficial for several reasons. While there is no cure, there are several medicines available to treat Alzheimers, along with coping strategies to manage behavioral symptoms. Beginning treatment early in the disease process may help preserve daily functioning for some time. Most medicines work best for people in the early or middle stages of the disease. Learn more about Alzheimers medications.
In addition, having an early diagnosis helps people with Alzheimers and their families:
Inappropriate Behavior And Loss Of Empathy
If someone who is usually sweet, considerate, and polite starts to say insulting or inappropriate things and shows no awareness of their inappropriateness or concern or regret about what theyve said they could be exhibiting an early sign of dementia. In the early stages of some types of dementia, symptoms can include losing the ability to read social cues and, therefore, the ability to understand why its not acceptable to say hurtful things.

Impact On Families And Carers
In 2019, informal carers spent on average 5 hours per day providing care for people living with dementia. This can be overwhelming . Physical, emotional and financial pressures can cause great stress tofamilies and carers, and support is required from the health, social, financial and legal systems. Fifty percent of the global cost of dementia is attributed to informal care.
What Are The Symptoms Of Alzheimers Disease
Early on, Alzheimers disease may be hard to notice. The first signs are usually memory loss and difficulty finding the right words for everyday things. However, many people have trouble with memory but dont have Alzheimers so its important to visit a doctor to work out the exact cause of memory problems.
Other common symptoms of Alzheimers disease include:
- vagueness in daily conversation
Alzheimers disease is sometimes classified into 3 stages, based on the severity of symptoms:
Symptoms will progress differently between people, depending on what areas of the brain are affected. A persons symptoms may also change from day to day and can become worse with stress, illness or tiredness.

Can You Prevent Alzheimers Disease
There is no sure way to prevent Alzheimers disease. However, you can reduce the risk of Alzheimers disease by caring for your health:
- your heart whats good for your heart is good for your brain so stick to a healthy diet and dont smoke
- your body regular physical activity increases blood flow to the brain so maintain an active lifestyle
- your mind an active mind helps build brain cells and strengthens their connections so socialise, do things such as puzzles and crosswords, and learn new things, such as a language
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.

What Are Secondary Complications Of Alzheimers Disease That Cause Death
Although Alzheimers disease devastates the brain, it does not kill the person. Secondary complications from decline in brain function lead to death.
The majority of people with Alzheimer’s disease die from aspiration pneumoniawhen food or liquid go down the trachea instead of the esophagus, causing damage or infection in the lungs that develops into pneumonia.
Moreover, neuronal death eventually leads to problems with swallowing and mobility. This predisposes the affected individuals to the risk of poor nutrition, dehydration, blood clots, falls, and infection.
What Is Known About Reducing Your Risk Of Alzheimers Disease
The science on risk reduction is quickly evolving, and major breakthroughs are within reach. For example, there is growing evidence that people who adopt healthy lifestyle habits like regular exercise and blood pressure management can lower their risk of dementia. There is growing scientific evidence that healthy behaviors, which have been shown to prevent cancer, diabetes, and heart disease, may also reduce risk for subjective cognitive decline.

Who Gets Alzheimers Disease
Anyone can develop Alzheimers disease, but it is more common in older age.
Genetics, lifestyle and health factors are associated with an increased risk of developing dementia.
In a few cases, Alzheimers disease is inherited, caused by a genetic mutation. This is called familial Alzheimers disease, with symptoms occurring at a relatively young age. This is usually when someone is in their 50s, but sometimes younger.
How Can Healthcare Professionals Help At This Stage
Healthcare professionals can explain these changes so you understand what is happening.
Healthcare professionals can also take steps to reduce the persons pain or distress, often using medication.
If the person cant swallow, then medication can be provided through patches on the skin, small injections or syringe pumps that provide a steady flow of medication through a small needle under the persons skin. Speak to a GP or another health professional about this.

What Causes Alzheimer Disease
Lots of research is being done to find out more about the causes of Alzheimer disease. There is no one reason why people get it. Older people are more likely to get it, and the risk increases the older the person gets. In other words, an 85-year-old is more likely to get it than a 65-year-old. And women are more likely to get it than men.
Researchers also think genes handed down from family members can make a person more likely to get Alzheimer disease. But that doesn’t mean everyone related to someone who has it will get the disease. Other things may make it more likely that someone will get the disease, such as high blood pressure, high cholesterol, Down syndrome, or having a head injury.
On the positive side, researchers believe exercise, a healthy diet, and taking steps to keep your mind active may help delay the start of Alzheimer disease.
Not Understanding What Objects Are Used For
Now and again, most people find themselves desperately searching for the right word. In fact, failing to find the word youre thinking of is surprisingly common and not necessarily a sign of dementia, says Rankin. But losing knowledge of objects not just what they are called but also what theyre used for is an early dementia symptom. Oddly enough, people who are losing this knowledge can be very competent in other areas of their lives.

What Should I Expect As Dementia Progresses
Most forms of dementia are incurable and get worse over time. Although your loved one could be mostly independent for a while, theyll eventually need assistance with daily tasks such as bathing, dressing, and cooking. Its also important to remember that their safety could become a concern.
If you anticipate their needs increasing, home care supports families while enabling seniors to continue living at home for as long as possible. Remaining in a familiar place can be especially helpful for people with dementia.
In later stages of dementia, living at home may no longer be an option. Memory care communities are a specialized type of senior living designed to meet the unique needs of someone experiencing memory loss or cognitive decline.
Talk With Close Family Members Or Friends
Ask others who know your loved one if theyve noticed any changes. Try to do this confidentially and respectfully to avoid upsetting your loved one.
Some people with early dementia become good at covering up their memory lapses. It can be harder for them to do this around those who know them well, however. It can be helpful to find out if others have noticed the same things you’ve been noticing. You may find they have the same concerns but weren’t sure if they should say anything.
Of course, your goal is not to spread rumors or gossip. Instead, your goal should be to help your loved one by sharing information with others who are close to that person.

Conditions With Symptoms Similar To Dementia
Remember that many conditions have symptoms similar to dementia, so it is important not to assume that someone has dementia just because some of the above symptoms are present. Strokes, depression, excessive long-term alcohol consumption, infections, hormonal disorders, nutritional deficiencies and brain tumours can all cause dementia-like symptoms. Many of these conditions can be treated.
What Is The Difference Between Alzheimer’s And Dementia
First, some explanation of dementia vs. Alzheimer’s. According to the Alzheimer’s Association, dementia is a general term for a decline in mental ability that interferes with daily life. Not a normal part of aging, most dementias are typically caused by damaged brain cells.
Of all the dementias, Alzheimer’s disease is the most common, accounting for 60-80% of the cases. In other words, it is a specific disease while “dementia” is a general term for a life-altering decline in brain function .

What Should You Tell Someone Who Has Alzheimers Disease
- Howard E. LeWine, MD, Chief Medical Editor, Harvard Health Publishing
It’s not just your loved one’s life that changes with an Alzheimer’s disease diagnosis. Your own life is also dramatically altered as you assume the role of caretaker. Several important issues should be addressed as soon as possible. You must also learn how to handle the day-to-day challenges of caring for a person with Alzheimer’s disease.
Most experts say that if the affected person asks you what’s wrong with them, you should be honest. Knowing that the problem is a disease, not “insanity,” is often a relief for the person affected. Telling someone who has not asked may be helpful, particularly if the person appears troubled about his or her condition. Generally, it’s best for the physician to explain the diagnosis. New information doesn’t always “stick,” however, so don’t be surprised if someone with Alzheimer’s disease continues to ask what’s wrong. In such cases, you can offer a reassuring but brief explanation.

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:

Why Early Detection Can Be Difficult
Alzheimers disease usually is not diagnosed in the early stages, even in people who visit their primary care doctors with memory complaints.
- People and their families generally underreport the symptoms.
- They may confuse them with normal signs of aging.
- The symptoms may emerge so gradually that the person affected doesnt recognize them.
- The person may be aware of some symptoms but go to great lengths to conceal them.
Recognizing symptoms early is crucial because medication to control symptoms is most effective in the early stages of the disease and early diagnosis allows the individual and his or her family members to plan for the future. If you or a loved one is experiencing any of the following symptoms, contact a physician.
What Are The Warning Signs Of Alzheimers Disease
Symptoms usually develop gradually and worsen over the years. Symptom progression varies from person to person and mostly manifests as forgetfulness in the initial stages.
One or more of the following symptoms may be present in someone with Alzheimer’s disease:
- Memory loss that disrupts daily life such as getting lost in a familiar place or repeating questions
- Inability to recognize familiar faces
- Trouble handling money and paying bills
- Difficulty completing basic tasks at home, work, or leisure

Alzheimers Quotes And Sayings
I think the best thing I ever did with my life was stand up and say Ive got Alzheimers. Terry Pratchett
You cant converse with Alzheimers sufferers in the way you do with others the dialogue tends to go round in circles. Kevin Whately
Without the aid of the visual cues of the person she talked to, conversations on the phone often baffled her. Words sometimes ran together, abrupt changes in topic were difficult for her to anticipate and follow, and her comprehension suffered. Although writing presented its own set of problems, she could keep them hidden from discovery because she wasnt restricted to real-time responding.
Lisa Genova, Still Alice
Alzheimers Behaviors To Track
For each of these behaviors, try to make note of the following:
- Whether theres been a decline or change compared to the way your parent used to be
- Whether this seems to be due to memory and thinking, versus physical limitations such as pain, shortness of breath or physical disabilities
- When you or another person first noticed problems, and what you observed
- What kinds of problems you see your parent having now
If you dont notice a problem in any of the following eight areas, make a note of this. That way youll know you didnt just forget to consider that behavior.
