The next time you forget a word, before you spiral — I want you to know something. Not all memory slips are created equal. Most of the ones that scare us aren't what we think they are. I had one this week, and it prompted me to do a little investigation...
Before you spiral the next time you forget a word...
Most likely, your brain's not breaking.
I know that's not what the fear says. The fear says: "This is how it starts."
It whispers that what just happened, that small fumble with a word, that moment of blankness, is the first tile in a pattern you're terrified to name.
I know that fear intimately. I carry the APOE4/4 gene — the highest genetic risk factor for Alzheimer's disease. I watched my mom lose herself to dementia. And I still feel the cold flash of worry when the right word won't come.
I want to be clear that I'm not a neurologist or neuroscientist. I am a Brain Longevity Specialist and Bredesen-trained, and have been a Health and Life Coach since 2012.
But I did this research because I was scared after a few random memory slips — and what I found reassured me enough that I wanted to share it. We deserve better than vague reassurance. I hope to help shed a bit of light on the difference between what is rarely concerning vs. what really is something to pay attention to.
My Memory Slip Story
I had a few similar memory slips this week. Tried to remember the name of a restaurant, Ball Square, and what came to mind was the word "Bell." I knew it wasn't right, but I also knew it was close. Perhaps it rhymes, I said. My brain got the shape of the word, the sound of it, and the number of syllables. It just landed on the wrong version of the right sound.
Turns out, there's a name for this: phonological approximation.
Our brain retrieves the sound structure of a word correctly, but lands on a close neighbor instead of the exact target. Research from Cambridge University, published in the Journal of Cognitive Neuroscience, confirms that this is a well-documented and normal phenomenon — one that becomes more common with age, but not because the retrieval system is failing. The memory is intact. The brain found the neighborhood, but it just couldn't pinpoint the exact house.
Whew. It felt like a relief to learn that.
Another time, I found myself describing something using three words instead of landing on the one precise word I was looking for. The concept was completely there. It wasn't until after I described it in three words and my husband said the "correct word" that I realized what I had done and that the "correct" word was just slightly out of reach.
I did experience a moment of fear. But I didn't spiral because I also knew my context.
I'd traveled across time zones, and my sleep was disrupted. I stopped taking creatine for a lab test. I hadn't lifted weights in over a week.
Research consistently shows that even partial sleep restriction impairs memory retrieval and that elevated cortisol during stress impairs word recall. My brain was running on less fuel and less recovery than usual, and precise word retrieval can be one of the first things to feel it.
Context is important information to consider. Without it, any memory slip becomes evidence of our worst fear. Which then adds more stress and potentially exacerbates our word and memory retrieval. With context, we can actually think clearly.
What the Research Actually Says
Not all memory slips come from the same place, and this distinction matters enormously — both for reducing unnecessary fear and for knowing when to actually pay attention.
The ones that are rarely concerning:
-
Forgetting why you walked into a room — then remembering when you return. This is context-dependent memory, which occasionally occurs at all ages.
-
Tip-of-the-tongue — knowing the word exists, almost having it, getting a sound-neighbor instead of the target word. Ball instead of Ball Square. The retrieval system is working, but it just needs a moment.
-
Using more words to describe something instead of finding the exact one, especially when tired, stressed, or managing too many things at once.
-
Forgetting something you were told while doing three other things — you weren't encoding it in the first place.
-
Blanking on a name in the moment — then remembering it twenty minutes later.
One important caveat before we go further: the list above is only reassuring when these slips are occasional and contextual — happening when you're depleted, distracted, or running on fumes. If they're occurring frequently, or during optimal conditions when you're well-rested and not under unusual stress, the frequency itself is data. A single tip-of-the-tongue moment is normal. A dramatic increase in how often it happens, especially without an obvious explanation, is worth paying attention to just as much as the type of slip. Research confirms that frequent subjective memory complaints, including word-finding difficulty, can be a very early signal worth tracking, even when each individual instance seems benign. This isn't about fear. It's about knowing your baseline well enough to notice a genuine shift.
And if, deep down, you think this is happening outside the range of "normal," it's especially important not to ignore it, because this early window is when our brains are most receptive to prevention interventions.
The ones worth paying attention to:
-
As stated above, if there's a more consistent or dramatic increase in memory concerns without an obvious explanation.
-
Forgetting the word and losing the concept entirely — not knowing what the thing is, not just what it's called. This is called semantic loss, a categorically distinct neurological process.
-
Repeatedly asking the same question or telling the same story in the same conversation — not once, but as a pattern.
-
Getting lost in familiar places.
-
Forgetting the name of someone in your close family, work, or friend circle (someone you see and interact with very regularly).
-
Difficulty following a sequence of steps you've done hundreds of times. Including recipes.
-
Losing track of conversations you were just having — not just a detail or two, but the whole thread.
The difference isn't the forgetting. It's whether the information is still in there somewhere, temporarily hard to retrieve, versus whether it seems to have disappeared entirely.
Lisa Genova, Harvard-trained neuroscientist and author of Still Alice, puts the sharpest version of this distinction I've ever heard: the difference between forgetting where you parked your car, and forgetting that you own a car.
What Your Brain Is Trying to Tell You
It's so natural to worry, but our memory and cognition are impacted by our lifestyle and biology, and even the ones worth paying close attention to do NOT mean you're experiencing true cognitive decline or neurodegenerative disease.
Our brain's memory challenges can involve sending signals about our bodies and what they need more of or are struggling with.
Here are the places worth looking first:
Sleep. This is rarely the dramatic one, but it's almost always the first one. Even one night of partial sleep restriction measurably impairs memory consolidation and word retrieval. If you're waking up at 3am, running on six hours, or sleeping through the clock but not actually restoring, your brain will tell you. Your words will tell you.
Blood sugar and insulin sensitivity. Glucose is your brain's primary fuel. When blood sugar swings—even in ranges that look "normal" on a standard panel—cognitive clarity often goes with it. The brain is actually more sensitive to these fluctuations than a fasting glucose or A1C will reveal. If you want real data, a continuous glucose monitor will show you what's happening between the numbers.
Chronic stress and elevated cortisol. There's direct research showing that cortisol impairs the hippocampus — the brain structure most responsible for memory encoding and retrieval. Chronic stress isn't "just stress." It's a neurological environment. If you've been running on high alert for months, that's not a personality flaw. It's physiology.
Micronutrients your brain depends on. B12 and folate deficiency are among the most overlooked causes of cognitive symptoms — and they're correctable. Add magnesium (especially for sleep disruptions), creatine (it depletes with stress and restricted diet and directly supports cognitive performance), and for those with MTHFR variants, the form of folate matters enormously. Standard folic acid doesn't convert properly. These aren't supplements for optimization, they're basics for function.
Thyroid function. Hypothyroidism mimics cognitive decline so closely that it has a clinical nickname: pseudo-dementia. Brain fog, word-finding difficulty, memory slips — these can all be thyroid. And a standard TSH tells only part of the story. Free T3 and free T4 complete the picture. If you haven't had a full thyroid panel, it's worth asking for one.
Your gut. The gut-brain axis is no longer fringe science. Dysbiosis—an imbalanced gut microbiome—directly affects neurotransmitter production, systemic inflammation, and cognitive function. If your digestion is off, your brain is likely getting the message.
Medications. Antihistamines, proton pump inhibitors, benzodiazepines, and a class of drugs called anticholinergics all have documented cognitive side effects — some of which are reversible when the medication is stopped or changed. If you started something new and noticed a shift, that's a hypothesis worth bringing to your doctor.
This list is important to keep in mind because they are findable and fixable.
Lab work, lifestyle shifts, and a conversation with a physician who's willing to look at the whole picture can lead to real interventions with real effects on your brain's performance.
Your memory slips may not be early Alzheimer's. They may be your body telling you it needs something.
The question isn't only: am I losing my memory?
It's also: what is my body trying to say?
When to Stop Reassuring Yourself and Get Data
If something feels consistently and unexplainably different from your baseline, not one bad week, not a stretch of disrupted sleep, but a sustained shift in how your mind is working — that warrants a proper neuropsychological evaluation.
This is when we turn worry into real data. It's always better than ambient dread.
A proper evaluation gives you a baseline, a more complete picture, and something concrete to work with.
It replaces the fear loop with honest information.
And if we want the time and power to do something preventive, we need to know (now).
We may think we want vague reassurances.
But what we need is to know the actual reality, with enough context to do something about it.
You deserve information. Not fear.
And if you're not sure whether what you're experiencing is one or the other, that question alone is worth exploring.
Two books that dive deeper into memory:
Remember: The Science of Memory and the Art of Forgetting — Lisa Genova The most accessible, humane book on memory I've read. Genova is a Harvard-trained neuroscientist and the author of Still Alice — she understands both the science and the terror, and she writes for people who want to understand, not just be reassured. Start here.
Seven Steps to Managing Your Memory — Andrew E. Budson, MD This is the clinical companion. Budson is a professor of neurology at Boston University, and this book is used by actual memory clinics. If you want a rigorous framework for understanding what's normal, what's not, and when to seek evaluation, this is it. More technical than Genova, but deeply grounded.
