We think it's normal for an adult in our home, like our mom, dad, grandma, or aunt, to forget things as they get older. We often hear things like, "Where did I put the mirror?" "Why did I come into this room?" But have you ever felt like these forgetfulnesses are a little more serious? Do you feel like your memory has gotten worse this year than last year, or has a friend told you about this? This is really not something we should take lightly. A new medical study suggests that significant changes in memory like this may be an early warning sign of Alzheimer's disease.
What did new research reveal?
The study, recently published in the prestigious medical journal Neurology, involved 675 people with an average age of 72. Although these people were identified as being at risk for developing Alzheimer's disease, none of them had major problems with their cognitive skills when the study began.
What this study did was very simple. These 675 people and their closest friends (that could be their partner, relative, or best friend) were asked about changes in their memory through a questionnaire. At the same time, all of them underwent a special brain scan.
The results are quite surprising. People who reported that they or someone close to them "have a lot less memory this year than they did last year" have seen the first changes in their brains that are associated with Alzheimer's disease. The message from this is that if an older person complains about their memory or their family is concerned about it, it's not a good idea to just dismiss it as "just because they're getting older."
What are these memory changes that you should be concerned about?
You might be wondering what kind of forgetfulness we should be concerned about. There are a few things they specifically focused on in the research. See if these are common to the adults in your home.
| Sign to pay attention to | Simply put... |
|---|---|
| Significant decline in memory | Do you or others feel that your memory is much weaker this year than it was last year? |
| Forgetting where things are | Do you often forget where you keep your keys, glasses, or purse? Is this more common than before? |
| Relying on written notes | Do you rely more on things like making a shopping list or keeping a to-do list? |
The results of the cognitive performance tests used in this study also matched what these people said about themselves, meaning that their "I don't remember" feelings were actually well-founded.
Brain changes and Alzheimer's disease
Alzheimer's is a condition in which brain cells are gradually destroyed over time, with symptoms becoming more severe. It is mainly caused by two types of abnormal proteins that accumulate in the brain. Researchers used a special scanning technique called `PET` scan (positron emission tomography) to see if these proteins were deposited in the brain.
1. Amyloid Plaque: This is like "scars" that accumulate between brain cells. When these accumulate, they disrupt the flow of information between brain cells.
2. Tau Tangles: Tau is another protein found inside brain cells. In Alzheimer's disease, these proteins clump together like a ball of string, forming "tangles." This causes the cells to die without getting the nutrients they need.
But it's important to remember this. Just because someone has these proteins in their brain doesn't mean they have Alzheimer's disease. Also, not everyone who has these changes will necessarily develop the disease. These are only risk factors for the disease.
This study made it clearer than ever that people who complain of memory loss are more likely to have these 'tau' protein tangles in their brains.
So, why do we need to think about this so much?
According to Dr. Rebecca Amariglio, one of the leaders of this research, this information is very important for us. She says:
"We now know that Alzheimer's disease begins to cause changes in the brain long before a doctor can clinically detect symptoms. There is now considerable evidence that the first time someone notices these memory changes, either in themselves or in a family member, may be an early warning sign of the disease."
Simply put, that feeling of "I'm forgetting things a lot these days" that you or someone close to you is a very valuable medical clue . Don't ignore it. It could be your body's first warning. If you're feeling this way, the best thing to do is not to panic, but to talk to your doctor about it.
The researchers also note that most of the participants in this study were white and highly educated, suggesting that further studies are needed in countries with diverse populations, such as Sri Lanka.
Take-Home Message
- If you, your loved one, or another family member notices that their memory has been significantly declining recently, especially over the past year, don't ignore it.
- Things like frequently forgetting where things are and relying more on written notes to get things done can be early signs of Alzheimer's disease.
- This memory loss may be related to proteins called amyloid plaques and tau tangles that accumulate in the brain.
- If you have concerns about your memory or the memory of a loved one, don't panic or be afraid, but see your family doctor (doctor) and talk about it.
- Being aware of a disease early on will go a long way in helping you manage the condition better in the future.
