Alzheimer’s disease is a leading cause of death in the United States, and millions of Americans are affected by the disease.
It’s important to distinguish the facts from the myths about Alzheimer’s, especially when it comes to finding information online. Read on to learn about common myths surrounding this disease.
- Alzheimer’s disease and dementia are the same thing
People often use the terms Alzheimer’s disease and dementia interchangeably, but there is a difference.
Dementia refers to impaired memory, thinking, reasoning, and behavior, and Alzheimer’s is just one type of dementia.
The terms are likely confused because Alzheimer’s is the most common cause of dementia and the most well-known.
But there are other types of dementia, too, including Lewy body dementia, frontotemporal dementia, and vascular dementia.
- I will develop Alzheimer’s disease if my parent has it
If a parent or close relative has Alzheimer’s disease, you may be worried about developing it as you get older.
A person’s chance of developing Alzheimer’s is higher if they have certain genetic mutations or variations that can be passed down from a parent.
However, just because a biological parent has Alzheimer’s does not mean that their children will develop it.
Alzheimer’s disease is complex, and scientists don’t yet fully understand what causes it in most people. Research suggests that in most individuals, a host of factors beyond genetics play a role in the development and course of the disease.
Environmental and lifestyle factors, such as exercise, diet, exposure to pollutants, and smoking may also affect a person’s risk for Alzheimer’s.
Although we don’t yet know how to prevent Alzheimer’s, it’s important to practice healthy behaviors throughout your lifetime, such as exercising regularly and eating a balanced diet.
- Only people in their 70s and older get Alzheimer’s disease
While the greatest known risk factor for Alzheimer’s is age, that does not mean that only older adults develop it. For most people with Alzheimer’s, it’s true that symptoms first appear in their mid-60s or beyond.
However, some people experience symptoms earlier, even as young as their 30s. When a person develops Alzheimer’s between their 30s and mid-60s, it’s called early-onset Alzheimer’s.
Early-onset Alzheimer’s is rare — representing less than 10% of people with Alzheimer’s. Developing Alzheimer’s earlier in life can present specific challenges.
People diagnosed at younger ages may be more likely to be raising children who are still at home or managing work and having to apply for disability than those who are diagnosed at older ages.
Many people with Down syndrome, a genetic condition, will also develop Alzheimer’s at an earlier age and may begin to show symptoms in their 40s.
- Alzheimer’s disease symptoms are normal as we get older
Many people become more forgetful as they age, and some forgetfulness, such as losing things from time to time, is normal.
However, common signs and symptoms of Alzheimer’s, such as making poor judgments and decisions a lot of the time, having problems recognizing friends and family, or losing track of the date or time of year are not a normal part of aging.
If you are worried about your memory or other possible Alzheimer’s symptoms, talk with your doctor.
The doctor may ask questions about your health history, perform assessments of your thinking and memory, and carry out medical tests to determine your diagnosis.
