Dementia is the seventh leading cause of death worldwide, and though it is not considered a part of normal aging, there are more than 55 million people living with dementia around the globe. Despite this, there are a lot of misconceptions about dementia. Here are things to note to help you better understand the people affected by this disorder.

Dementia can have drastic effects on your life

1. Alzheimer's disease is the most prevalent form of dementia

Dementia is an umbrella term that describes multiple different diseases involving a progressive loss of memory and thinking ability. The most well-known of these diseases is Alzheimer's. Alzheimer's is also the most common form of dementia, accounting for over half of all dementia diagnoses.

2. Younger people can get dementia, too

It may be common knowledge that dementia is more common in older adults, but not everyone realizes a person can get dementia before age 65, though it is less common. Age is the strongest known risk factor, but it is not unheard of for someone in their 40s or younger to get it. For example, early-onset Alzheimer's is a form of dementia that usually impacts people in their 40s and 50s.

3. Exercise may help prevent developing dementia

Healthy habits, like not smoking and getting regular exercise, may reduce the chances of developing dementia. Exercise can help maintain heart health and a normal blood pressure, which is important as research shows that high blood pressure is a risk factor for developing dementia. Exercise can also help manage dementia symptoms if you already have them. 

4. Dementia can lead to death

While you may not die from the disease itself, many of the complications can be fatal. For example, for Alzheimer's, as the disease progresses, the following risks apply:

  • Alzheimer's disease increases difficulty swallowing, which can lead to choking. Caregivers should ensure that their loved one isn't choking on their food whenever they eat.
  • Alzheimer's weakens the immune system, making patients more prone to infections.
  • Pneumonia may result from choking or swallowing difficulties associated with Alzheimer’s and other dementias and can sometimes be fatal.

5. More women get Alzheimer's than men

Women are more likely to get Alzheimer's than men are, likely because women tend to live longer, and the risk increases with age. In the US, about two in three patients with Alzheimer's are women.

6. Dementia symptoms can vary

You might know that dementia can affect memory and sense of self. However, dementia can affect some people in other ways.

Patients with dementia may hallucinate or have trouble speaking, experience a change in food preferences, develop new personalities, forget how to do familiar tasks, and more. Some may keep their memories but lose other mental abilities. The variety in symptoms is part of why dementia is difficult to treat.

7. There is no cure

Some forms of dementia may be prevented, and disease progression may be slowed, but to date, there is no cure for them. With Alzheimer's, there is no cure and not always a clear way to slow down the disease. Sometimes, you can treat the symptoms through medication and therapy, but no cure has been developed as of now, though researchers are working on it.

8. Dementia research is underfunded

Dementia research is still underfunded compared to other diseases, despite its prevalence. While this is somewhat understandable, as diseases like cancer and heart disease are still the top killers, with the numbers rising, one would expect that the research dollars would catch up. If you are passionate about the search for a way to prevent or cure dementia, it's an excellent time to join the fight and advocate for increased funding of dementia research.

9. Scientists are unsure what causes Alzheimer's

The brain is more complex than many imagine, and figuring out the underlying causes of Alzheimer's is difficult. Researchers don’t yet fully understand what causes Alzheimer’s. It is speculated that genetics and lifestyle contribute to the chances of getting the disease, but nothing is concrete yet. Some forms of dementia have more of a definite cause, but for Alzheimer's, the evidence is still inconclusive.

10. Every minute, someone in the US develops Alzheimer's

There is a new Alzheimer's diagnosis made, on average, about every 66 seconds in the US.

Dementia and race

Alzheimer's affects people of different races at different rates. African Americans may have about twice the risk of dementia as white people; Hispanics are 1.5 times as likely to develop it.

Dementia worldwide

Some may believe dementia only affects people in Western societies, but this is not true. There have been many cases in the East, especially in China. Dementia is a worldwide phenomenon.  About 60% of people with dementia live in low and middle-income countries,  

According to the World Health Organization, the Global Action Plan on the Public Health Response to Dementia “aims to improve the lives of people with dementia, their carers, and families, while decreasing the impact of dementia on communities and countries.”

Caregivers of people with Alzheimer's

Although it is possible to live with dementia and be independent, at some point, a person with dementia may need a caregiver to help them with their daily life. About four out of five caregivers are unpaid, and they are usually friends or family members.

Caregivers are usually women; many are the daughters of people with Alzheimer's. Taking care of a person with Alzheimer's is stressful for the family, with many facing financial, emotional, or physical hardships. There are significant economic costs of dementia.

The costs of Alzheimer's

Annually, the cost of dementia care may be over a quarter trillion. By 2050, the cost may be over a trillion by the standards of the value of the dollar today. People with dementia require more health care and hospitalizations and account for many nursing home residents.

Diagnosing early

While there is no way to prevent many forms of dementia, diagnosing early can help. This allows the person diagnosed with dementia to plan how they want to spend the rest of their life while they still can. Also, early diagnosis can save money in the long run. 

Counseling can be helpful for everyone involved with dementia

Dementia can have drastic effects on your life

Dementia can be stressful to live with. If you have been diagnosed with dementia, you may need someone to take care of you as you experience difficulty with cognitive functions. This can lead to a loss of motivation and uncertainty about how to live the rest of your life.

Meanwhile, the caregivers of those with dementia often face significant stress. They might feel physically and mentally exhausted and worry about the future of their loved one, as well as their finances. Talking to someone who understands can help. Look for a support group either online or in your area, or consider connecting with a therapist. 

Online therapy can help

While no solution fits every situation, one way to find help is through counseling. A good counselor might be able to give the patient with dementia motivation to carry on and help caregivers make time for themselves and take care of their mental health.

Online therapy has many benefits for a person living with dementia and their caregivers. You don’t have to worry about getting to and from appointments in an office or being put on a waiting list. With online therapy, you’re matched with an available counselor so you can start treatment right away. 

Research shows that online therapy has positive long-term effects when it comes to treating a variety of conditions. One review showed that people who participated in online therapy saw a 50% reduction in symptoms of generalized anxiety disorder, panic disorder, and depression, as well as a decreased impact of chronic fatigue and stress. If you’re interested in beginning online therapy yourself, reach out to a BetterHelp therapist to get started.

Takeaway

Although there are multiple forms of dementia, a condition experienced by people worldwide, it is still misunderstood in many ways. If you have early signs of dementia or are caring for someone who does, online therapy can help you learn how to manage the tough times ahead.
