Dementia is a broad term that refers to a decline in mental capabilities. The condition can entail problems with memory, language, thinking, and judgment. People with dementia may have difficulty doing everyday tasks, and they may eventually need help with all aspects of their care.

There are many different causes of dementia, and it can occur at any age. However, it is most common in older adults. Dementia is not a normal part of aging, and it is not something that can be cured. However, there are treatments that can help people with dementia manage their symptoms and improve their quality of life.

If you or someone you know is experiencing symptoms of dementia, it is important to see a doctor for a diagnosis. Early diagnosis and treatment can help slow the progression of the disease and improve the person’s quality of life.

This article delves into common questions surrounding this condition. Read on and learn more.

What Is Dementia?

Dementia is a general term for the diminishing of cognitive function. This can manifest in problems with memory, language, thinking, and other executive functions that are important for daily living.

For some people, dementia may be a mild condition that does not significantly interfere with their life. However, for others, it can be a much more serious condition that can lead to a decline in physical and mental abilities and, eventually, death.

Dementia is not a normal part of the aging process. It is a group of disorders that are caused by changes in the brain. These changes can lead to a decline in cognitive abilities, which can make it challenging to live independently and can also cause changes in behaviour and emotions.

What Are the Symptoms of Dementia?

People with dementia often have trouble with activities of daily living, such as bathing, dressing, eating, and more. They may also have mood and behaviour changes.

If you notice your aging relative exhibiting new or unusual behaviours, it’s essential to keep track of these changes and discuss them with their physician. Dementia symptoms can have a significant impact on their future care, so early detection is critical. The dementia symptoms to look out for include:

  • Changes in personality
  • Financial struggle
  • Inability to track time
  • Lost interest in previously loved hobbies
  • Newly developed difficulty when speaking or writing
  • Severe mood swings
  • Social withdrawal
  • Trouble focusing on work

What Are the Stages of Dementia?

There are seven stages of dementia, and each stage is associated with different symptoms.

  1. No cognitive decline
  2. Age-associated memory impairment
    • Some seniors may have difficulty with things like remembering where they put their glasses or the names of acquaintances, but they can usually do well on clinical interviews.
  3. Mild cognitive decline
    • If you’re having trouble finding common destinations, struggling at work, or forgetting words or names, it could be a sign of mild cognitive decline.
  4. Mild dementia
    • As people age, they may start to forget things. This can include personal history, current events, and even simple tasks. People with mild dementia may have trouble recognizing people they know and struggle to do everyday activities. They may also become more anxious and withdrawn.
  5. Moderate dementia
    • A person with Alzheimer’s may have trouble doing everyday tasks, like getting dressed or brushing their teeth. They may also have difficulty remembering things that have happened recently or people’s names.
  6. Moderately severe dementia
    • In stage 6 of Alzheimer’s disease, patients often have difficulty remembering the names of their spouses or children. They may also have trouble with cognitive tasks such as counting and recalling words. In addition, they may suffer from incontinence and sleep disruptions.
  7. Severe dementia
    • As cognitive decline progresses, people lose the ability to communicate verbally and perform basic motor skills. This is because the brain is no longer able to send the correct signals to the body, telling it what to do.

What Can Cause Dementia?

The brain is a complex organ that is responsible for a variety of functions. It is divided up into regions, each of which is responsible for different functions. When cells in one of these regions become damaged, that part of the brain can no longer carry out its usual functions.

One of the most critical functions of the brain is to control movement. This is done by the motor cortex, a region of the brain that is responsible for sending signals to the muscles. When this region is damaged, a person can no longer move their muscles properly.

Another vital function of the brain is to process information from the senses. This is done by the cerebral cortex, the outermost region of the brain. This region is responsible for conscious thought, and when it is damaged, a person can no longer think properly.

The brain also controls the autonomic nervous system, which maintains an individual’s involuntary functions like heart rate and breathing. This is done by the hypothalamus, a small region of the brain located just above the brainstem. When this region is damaged, a person can no longer control their body’s involuntary functions properly.

There are many other regions of the brain that are responsible for different functions. Damage to any of these regions can lead to problems with the corresponding function.

Alzheimer’s disease, the most common type of dementia, is a brain disorder that slowly destroys the patient’s memory and cognitive skills. In the later stages of the disease, people may have difficulty with even basic daily living tasks.

The cause of Alzheimer’s is not fully understood but is thought to be plaques and tangles in the brain that damage brain cells and the connections between them. These plaques and tangles are a build-up of a protein called beta-amyloid. Beta-amyloid is produced by normal cells in the body, but in Alzheimer’s disease, there is an abnormal build-up of this protein. It still needs to be made clear why this happens.

There are currently no effective treatments for Alzheimer’s disease. However, there are treatments available that can help manage the symptoms of the disease and improve quality of life. There is also active research taking place into potential therapies for Alzheimer’s disease.

If you are worried about your memory or cognitive skills, it is important to see your doctor. They will be able to assess your symptoms and rule out other potential causes. If you are diagnosed with Alzheimer’s disease, there are support services available to help you and your family.

What Are Dementia’s Risk Factors?

The risk of developing dementia also increases if you have a family history of the condition. If your parent or sibling has dementia, your risk is increased by 50 percent.

While it was previously thought that only age influenced the development of dementia, researchers now believe that there are other risk factors too. They include the following:

  • Age
  • Chronic depression
  • Diabetes
  • Excessive drinking
  • Family history
  • Head injury
  • High blood pressure
  • Obesity
  • Parkinson’s disease
  • Sedentary lifestyle
  • Social isolation
  • Smoking
  • Stroke

How Is Dementia Diagnosis Made?

There is not one specific test that can definitively diagnose cognitive decline because there is still much unknown about dementia. Therefore, it is crucial to see a doctor as soon as possible after noticing any typical symptoms of dementia.

Geriatricians, doctors specializing in the care of older adults, take note of warning signs during regularly scheduled physical appointments and may perform a brief mental status exam. Some symptoms that may be of concern include:

  • Bruises and cuts
  • Difficulty maintaining basic hygiene
  • Noticeable weight loss
  • Unusual behaviours

If the primary care doctor suspects memory problems after administering a test, they may refer the person to a specialist for further testing to see if they have Alzheimer’s or another type of dementia.

Facing the possibility that a loved one has dementia can be difficult. Keep in mind that it is essential to see a doctor to rule out other potential causes of memory loss. There are many treatable conditions that can cause memory loss, such as thyroid issues, nutritional deficiencies, and infections. An official dementia diagnosis can be important for future treatment and for making decisions about when to enter memory care.

How to Cope With Dementia

A dementia diagnosis is a very significant event in someone’s life. It is important to remember that everyone experiences dementia differently and that the disease can progress at different rates for different people. Some people living with dementia may only experience mild to moderate symptoms, while others may experience a more rapid progression of the disease, which can lead to new behavioural concerns and changing care needs.

There is no single “right” way to respond to a dementia diagnosis. Still, it can be helpful to talk with a doctor, counsellor, or other professional about how to best manage the changes that come with the disease. It is also essential to begin planning for the future, as the disease will progress over time and care needs will change.

Caring for a Loved One With Dementia

There are a few medications that can help treat the symptoms of dementia. However, there is no cure for the disease. The most common medications used to treat dementia are cholinesterase inhibitors, which can help improve memory and cognitive function. Other medications, such as antipsychotics, can be used to treat specific symptoms, such as delusions or hallucinations.

There are many things you can do to care for a loved one with dementia at home. First, it is vital to create a safe and supportive environment. This means removing any potential hazards from the house, such as loose rugs or electrical cords. It is also important to provide plenty of stimulation, such as music, books, or puzzles. Finally, it is essential to be patient and understanding.

Choosing a Dementia Care Approach

It can be difficult to provide the care your loved one with dementia needs as the condition progresses. You may eventually need professional help, whether that means respite care for a short time or more permanent assistance. Look for a senior care option that will work best for your family’s needs.

Respite care is a type of care that is provided for a short time. This type of care is typically used to allow the primary caregiver to have a break from their caregiving duties. Respite care can be provided by different types of organizations and generally lasts for a day or up to several weeks.

If you are considering memory care for a loved one, it is vital to choose a community that is the right fit. There are many factors to consider, such as the severity of the dementia, the needs of the individual, the location, the cost, and more. Once you have chosen a memory care community, you will likely need to tour the facility and meet with the staff to get a better sense of what the community can offer your loved one.

In-home care services are not as organized as memory care, but they can be a good solution for seniors who want to stay in their homes. In-home care agencies might offer different levels of support depending on what the person needs. Make sure the care aide has experience working with seniors with dementia and has a list of the person’s symptoms to share.

Here are reasons to consider in-home care for dementia:

  • In-home care can help keep your loved one at home and out of a long-term care facility.
  • In-home care can provide one-on-one attention and supervision.
  • In-home care can help with activities of daily living.
  • In-home care can provide respite for caregivers.

Nursing homes provide care for seniors with significant health concerns that make it difficult for them to care for themselves. A doctor must prescribe this type of care and will often require a skills assessment and a physical examination.

Nursing homes don’t provide the same resources as memory care and aren’t designed specifically for seniors with dementia. Because of a higher resident-to-staff ratio, nursing homes aren’t ideal for aging adults with mild to moderate cognitive decline unless they require round-the-clock health care as well.


Dementia care is a process of providing care and support to people who have dementia. The care and support aim to maintain the person’s quality of life and independence for as long as possible.

There is no one-size-fits-all approach to dementia care, as the needs of each person will be different. However, there are some general principles that can be followed to ensure that the person with dementia receives the best possible care.
