What Is Dementia Disease?

Getting old is a unique situation for every human globally, but most problems can destroy this sweet dream for us. Dementia and Alzheimer’s are kinds of ills that cause many issues for seniors. Related to the approved reports from the world health organization, around 47.5 million people in the world live with dementia and Alzheimer’s. And more than 400,000 people in Canada live with this mind-destroying disease. But what is dementia? And how can we prevent dementia?

What Is Dementia?

Dementia is a general term for a loss of ability to recall, function, or make decisions that disrupt daily activities. The most prevalent form of dementia is Alzheimer’s disease. Dementia is not a normal part of healthy aging, even though it mainly affects older people. In other words, dementia is not a particular illness. Like heart disease, dementia is a general term encompassing many medical conditions, including Alzheimer’s disease.

Abnormal brain changes because the disorders are grouped under the common concept “dementia.” These changes cause a deterioration in cognitive ability, also known as thinking skills, significant enough to affect everyday life and independent functions.

In 2014, an estimated 5.0 million people over 65 had dementia, which is expected to rise to nearly 14 million by 2060. Due to the spread of the disease globally, health organizations set 21 September each year as a day of teaching and sharing information about dementia and Alzheimer’s in the world. However, the question is, is dementia a real dangerous side effect of aging? Read more about the difference between dementia and Alzheimer’s disease.

The answer is negative. Many seniors may be live without the symptoms of dementia. Still, they may experience other diseases such as muscle and bone deterioration, hardening of arteries and vessels, or reducing memory functions. These are some common signs of lowering memory in our age:

  • Lost keys in some places
  • The trouble with some names or words in a moment
  • Forgetting the name of cities, movies, etc.
  • Difficulty remembering some of our lives moments.

Why Does Someone Deal with Dementia?

Damage to brain cells causes dementia. The ability of brain cells to interact with one another is harmed as a result of this injury. When brain cells can’t communicate properly, it can affect one’s thoughts, actions, and feelings. The brain is divided into several regions, each performing a different function (memory, judgment, and movement).

When brain cells in a specific region are injured, that region cannot carry out its normal functions. Different forms of dementia are linked to particular types of brain cell damage in specific brain regions. High levels of certain proteins inside and outside brain cells, for example, make it difficult for brain cells to remain healthy and interact with one another in Alzheimer’s disease.

In everything about Alzheimer’s disease, you can find vulnerable information. Although the majority of the changes in the brain that cause dementia are irreversible and worsen over time, thought and memory problems caused by the following conditions may improve when treated or addressed:

  • Depression
  • Medication side effects
  • Excess use of alcohol
  • Thyroid problems
  • Vitamin deficiencies

What Are the Symptoms of Dementia Disease?

Many diseases are progressive, which means that the symptoms of dementia appear progressively and worsen over time. If you live with seniors and understand they have difficulties remembering things, or other activities that need thinking skills, don’t neglect their symptoms and bring them to the doctor as soon as possible.

A professional examination can reveal a condition that may be treatable. There is no single test to diagnose dementia. Doctors diagnose Alzheimer’s disease and other forms of dementia based on a thorough medical history, clinical examination, laboratory tests, and the distinct changes in perception, day-to-day function, and actions associated with each form of dementia. Doctors have a high degree of certainty in determining whether or not an individual has dementia. However, since different dementias’ signs and brain changes can overlap, it’s more challenging to pinpoint the exact form of dementia.

A doctor can diagnose “dementia” without specifying a form in some cases. A professional such as a neurologist, psychiatrist, psychologist, or geriatrician may be required if this happens. Also, these are some common symptoms of dementia in seniors:

  • Reduction of short-term memory
  • Forget the wallet or keys
  • Forget to pay bills or deposits
  • Forget to prepare meals
  • Forget the appointments
  • Forget the address of the home
  • Unable to complete tasks on their own
  • Difficulties in problem-solving, thinking or making a decision

Which Factors Will Increase the Risk of Dementia in People?

The most potent known risk factor for dementia is growing older, with most cases involving people aged 65 and up.

Many who have dementia-affected parents or relatives are more likely to develop the disease themselves. African Americans are twice as likely as whites to develop dementia as they get older. Hispanics are 1.5 times more likely than whites to develop dementia.

If not adequately controlled, high blood pressure, high cholesterol, and smoking raise the risk of dementia. Head injuries, mainly severe or often occur, may increase the risk of dementia.
Nevertheless, some procedures, like a healthy lifestyle, may help prevent dementia.

How Many Types of Dementia Exist?

Alzheimer’s is the most common type of dementia, accounting for 60 to 70 percent of all cases of dementia. But there are other types of dementia, such as:

  • Alzheimer’s disease
  • Vascular dementia
  • Lewy body dementia
  • Fronto-temporal dementia
  • Mixed dementia
  • Reversible causes

Dementia Treatments

Treatment for dementia depends on its cause. No cure or therapy will delay or stop the development of most progressive dementias, including Alzheimer’s disease. However, several drug therapies may help to alleviate symptoms temporarily. The same medications used to treat Alzheimer’s disease are also used to treat the symptoms of other forms of dementia. Non-drug treatments can also help with some dementia symptoms. Increased study support and participation in clinical trials can, in the end, lead to more successful new dementia therapies.

Volunteers are desperately needed for clinical research and experiments on Alzheimer’s and other dementias right now. The importance of a healthy lifestyle for seniors shows us how improving the lifestyle can help seniors prevent dementia.

How Can We Prevent Dementia?

Any dementia risk factors, such as age and genetics, are unchangeable. However, researchers are also looking into the effects of other risk factors on brain health and dementia prevention. Different lifestyle modifications, such as a healthy diet, not smoking, regular exercise, and mental functioning, can reduce the risk of cognitive impairment and may prevent dementia, according to research presented at the 2019 Alzheimer’s Association International Conference.

Also, brain games like the best card games for seniors are a good choice if you want to keep your brain functioning and prevent dementia. Furthermore, using omega-3 fatty acids, fruits, vegetables, and whole grains is suitable for our brain, particularly seniors.

How to Behave with Someone with Dementia?

We don’t come into this world knowing how to connect with dementia, but we can learn. Improving your communication skills will make caring for a loved one less complicated and almost certainly increase your relationship’s quality. As you care for a person with a dementing disorder, good communication skills will also help you deal with the challenging actions you can experience. In the top 10 podcasts for seniors 2021, you can find excellent podcasts for seniors and make them happy.

Have a Kind Manner

Your voice tone and body language communicate your emotions and thoughts more effectively than your words. Make a good impression on your loved ones by referring to them in a friendly and respectful way, using your voice tone and body language.

Activate the Person’s Interest

Reduce noise and distractions by turning off the radio or television, closing the curtains or closing the door, or moving to a quieter place. Make sure you have their attention before speaking by addressing them by name, identifying yourself by name and connection, and using nonverbal signals and touch to keep them focused.

In how to maintain the mental health of seniors, you can learn more about acceptable behavior with seniors, especially someone who deals with dementia or Alzheimer’s.

Explain Everything Clearly

Make your sentences and vocabulary as plain as possible. Slowly, clearly, and in a reassuring tone. Talk; instead of raising your voice higher or louder. If they don’t understand the first time, repeat your message or question with the exact wording. Wait a few minutes and ask the question again if they don’t understand. Instead of pronouns, use names of individuals and places.

Pose Easy-to-Answer Questions

Always ask simple questions; yes/no questions are the most efficient. Avoid posing open-ended questions or providing too many options. “Would you like to wear your white shirt or your blue shirt?” for example. Better still, show them the options—visual indications and help explain your question and direct them answer.

Listen to Them with All of Your Heart

Wait patiently for your loved one’s answer. It’s OK to suggest terms if they’re having trouble coming up with a response. Keep an eye out for nonverbal cues and body language, and respond accordingly. Often want to hear what the words say and how they make you feel.

Break Down Activities into Steps

Politely remind them of steps they forget and assist them with actions they can no longer complete independently. Many tasks become even more manageable as a result of this. You can help your loved ones by encouraging them to do what they can. Visual prompts can be extremely helpful, such as showing them where to place the dinner plate with your hand.

Reassure and Affectionately React

Dementia patients are often confused, nervous, and self-conscious. Furthermore, they are prone to getting mixed facts and recalling events that never happened. Avoid attempting to persuade them that they are incorrect. Keep your attention on the feelings they’re expressing (which are genuine), comfort, encourage and reassure them with verbal and physical expressions. When all else fails, holding hands, embracing, and praising the individual can be enough to get them to respond.

Talk About Good Memories

As probably you know, The Common Mental Disorders That Threatens the Elderly is forgetting the memories. Hence Reminiscing can be a relaxing and reassuring experience. Many people with dementia may not recall what happened 45 minutes ago, but they may vividly remember events from 45 years ago. As a result, refrain from asking questions that depend on short-term memory, such as what the individual had for lunch. Ask general questions about the person’s distant history instead; this knowledge is more likely to be remembered.

Always Keep Your Smile

Where necessary, use humor, but not to the detriment of the other person. People with dementia usually keep their social skills and are happy to joke with you. Don’t forget we can learn many patients from seniors, so reading the life lessons we can learn from the elderly is a good choice for you.


In every step of our lives, we face various problems and ills. We may experience new issues when we get older, especially in our minds, brain cells, or memory. With qualified education and modification of the nutrition, lifestyle, and physical activities, we can prevent dementia or Alzheimer’s disease.
