What Is Dementia Disease?

Getting old is a special situation for every human globally, but most problems can destroy this sweet dream for us. Dementia and Alzheimer‘s are some kinds of ills that cause a lot of problems 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? Stay with us.

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 common part of ageing, even though it mainly affects older people. In other words, dementia is not a particular illness; it’s a general term that encompasses a wide variety of medical conditions, including Alzheimer’s disease, similar to heart 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, with the number 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 ageing? If you are curious about the difference between dementia and Alzheimer’s disease, you can follow our next articles.

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.
  • Don’t remember 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 of which performs a different function (for example, memory, judgment and movement).

When cells in a specific region are injured, that region cannot carry out its normal functions. Different forms of dementia are linked to specific 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 can treat. No one test can be used to assess whether or not someone has 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 difficult to pinpoint the exact form of dementia.

A doctor can diagnose “dementia” without specifying a form in some cases. If this happens, a professional such as a neurologist, psychiatrist, psychologist, or geriatrist may be required. 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 powerful 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 all raise the risk of dementia. Head injuries, particularly if they are serious or occur often, may increase the risk of dementia.

How Many Types of Dementia Existed?

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

Ways of Treatment the Dementia

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 that are 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 changing the lifestyle can save seniors from dangerous illnesses such as dementia.

How Can We Keep Away from 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 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 active your brain functions. Also, use omega-3 fatty acids, fruits, vegetables, and whole grains are good materials for our brain, particularly seniors.

How to Behave with Someone with Dementia?

We don’t come into this world knowing how to connect with someone who has dementia, but we can learn. Improving your communication skills will make caring for a loved one less difficult 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 amazing podcasts for seniors and make them happy.

Have a Kind Manner

Your tone of voice and body language your emotions and thoughts are communicated more effectively through your body language than through your words. Make a good impression on your loved ones by referring to them in a friendly and respectful way. To help communicate your message and display your feelings of love, use facial expressions, tone of voice, and physical contact.

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 her focused.

Get down on her level if she’s seated and maintain eye contact. In how to maintain the mental health of seniors, you can learn more about adequate behaviour with seniors, especially someone who deals with dementia or Alzheimer’s.

Explain Everything Obliviously

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, lower the volume of your voice. If they don’t understand the first time, repeat your message or question with the same 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 try to 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 fine 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.

Do Activities Can Break down into a Sequence of Measures

Many tasks become even more manageable as a result of this. You can help your loved one by encouraging him to do what he can, politely reminding him of steps he forgets, and assisting him with steps he can no longer complete on his own. Using visual prompts, such as showing him where to position the dinner plate with your hand, can be extremely helpful.

Reassure and Affectionately React

Dementia patients are often perplexed, nervous, and self-conscious. Furthermore, they are prone to getting facts mixed up 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, touching, 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 Threaten the Elderly is forgetting the memories. Hence Reminiscing can be a relaxing and reassuring experience. Many people with dementia may have no recollection of what happened 45 minutes ago, but they may vividly recall 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 satire, but not to the detriment of the other person. People with dementia normally 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.


Humans, in every step of their lives, are faced with various problems and ills. Then when we are getting older maybe experience new problems, especially in our mind, brain cells or memory. With qualified education and modification of the nutrition, lifestyle and body activities, we can keep away from dementia or Alzheimer’s disease.

These numbers are terrifying. How poorly we know about our brain and brain health. It makes me sad when someone forgets something or has odd behaviour, especially when they’re old; they face adverse reactions, sometimes even insulation. People should know behavioural changes are important, especially for seniors. These changes can be symptoms of something treatable or something that can be prevented.

I was unfortunate enough to see my grandfather go through such pain. Now every day I’m getting closer to his age at that time, and every day I’m more afraid of what’s going to happen to me if I end up like him. He had my grandmother and the whole family there for him. I’m single and childless, and I have no one. I wish things like diseases didn’t happen to lonely people.
