November is Alzheimer’s Disease Awareness Month. This seems like a good time to share an article I was honored to write for SixtyandMe.
Many people are concerned about the prevalence of Alzheimer’s disease and other forms of dementia. Will it affect me someday? Or will it affect someone I love? What are the signs I should watch for?
You’ve probably seen the list of 10 Warning Signs from the Alzheimer’s Association. But did you know researchers are discovering more unusual early signs of Alzheimer’s disease and other forms of dementia?
Changes in balance or gait
Studies done in both the United States and France reveal that frequent falls may be an early sign of Alzheimer’s disease. The studies looked at people who otherwise appeared healthy but displayed Alzheimer’s-related lesions in their brains. Their fall rate proved to be more than twice that of the average person their age.
Interestingly, studies also revealed that a decline in walking speed may indicate early Alzheimer’s dementia. This was after ruling out other possible causes such as arthritis or muscle weakness.
Decreased sense of smell
Multiple research studies suggest a link between Alzheimer’s disease and difficulty identifying certain odors. This makes sense because the part of the brain associated with smell is one of the first areas affected by Alzheimer’s disease.
While the scents used in each study varied, some of the most common were peanut butter, peppermint, coffee, orange, and leather.
Scientists hope that someday a simple sniff test could provide an inexpensive and non-invasive test for Alzheimer’s disease. For now, they may use it as part of a battery of several tests to screen for early signs of Alzheimer’s dementia.
Unusual social responses
People experiencing early Alzheimer’s disease may display lengthy periods of staring into space. This is also common with another form of dementia known as dementia with Lewy bodies.
More recently, researchers discovered that people with a condition called frontotemporal dementia often have difficulty recognizing when other people tell lies or display sarcasm during conversations. This is because of damage to the area of the brain that controls judgment.
Changes in sense of taste
As Alzheimer’s disease affects the part of the brain involved with taste, people often experience changes in their food preferences. This, in turn, can lead to changes in appetite and weight.
Some people show increased cravings for sweets. Others lose interest in their favorite foods, resulting in weight loss. There are even situations where people don’t recognize that food is spoiled, or they consume inedible substances.
What to do if you see these signs
No one wants to consider that a loved one might develop Alzheimer’s disease or another form of dementia. Yet, it’s important not to ignore these early warning signs.
The good news is that many other conditions can cause these changes, and many of them are reversible. This includes medication side effects, certain vitamin deficiencies, and infections.
Your medical provider can do simple screening tests and provide referrals as needed. Even if it proves to be dementia, early diagnosis and treatment often lead to an improved quality of life.
