Myth 1: Alzheimer's disease and dementia are the same

Reality: The terms "Alzheimer's disease" and "dementia" are often used synonymously, but there is a difference between the two. Alzheimer's disease is just one type of dementia. Although Alzheimer's is the most common variant, there are other types of dementia as well.

Myth 2: Alzheimer's disease can be inherited

Reality: The likelihood of developing Alzheimer's disease with a genetic predisposition is certainly higher. However, one parent having the disease does not mean that their children will develop it.

Over the years, there have been many theories about the development of Alzheimer's disease — for example, it could be triggered by using aluminum cookware or the sweetener aspartame. However, none of these theories have been confirmed.

Myth 3: Only older people get Alzheimer's

Reality: Although the disease does occur more often after the age of 60, some people have their first symptoms as early as their 30s, 40s, or 50s. This variant is called early-onset Alzheimer's disease and occurs in less than 10 % of those affected.

Myth 4: The onset of symptoms is quite normal in older people

Reality: Forgetfulness is normal for many older people, but it does not always indicate Alzheimer's disease. A person who has trouble recognizing friends and family members, understanding what day it is, what time of year it is, or where their home is, should be concerned.

Myth 5: Alzheimer's disease cannot be prevented

Reality: This is only partly a myth. Scientists still don't know what causes Alzheimer's disease. It is believed to be caused by a combination of several factors including genetics, environment, and lifestyle. Although it is impossible to avoid the disease, it is still possible to reduce the risks by doing the following:

Control your blood pressure
Maintain a normal weight
Stay mentally and physically active
Avoid head trauma
Get 7-9 hours of sleep every night

A study published January 11, 2023, in Alzheimer's Research & Therapy shows that older adults can improve their physical fitness and cognitive function by increasing physical activity by 35 % or more.

Myth 6: There are treatments for Alzheimer's disease

Reality: Current medications do not cure the disease, but some medications alter the course of the disease by reducing people's cognitive and functional impairments early on. Other medications help reduce symptoms such as memory loss and confusion for a limited time. The earlier the diagnosis is made, the greater the chance the therapy will have an effect.

Myth 7: Alzheimer's disease only affects mental abilities

Reality: The disease also has physical symptoms including the following:

Loss of balance and coordination
Muscle tension
Shuffling when walking
Muscle weakness and increased fatigue
Problems with bladder or bowel control
Cramps and uncontrollable twitching
