Why does forgetfulness from stress happen and how is it different from dementia? Read about poor concentration, warning signs and ways to clear your head.
You walked into the kitchen and can't remember why. The car keys turn up on top of the fridge. While chatting with a friend, the name of a neighbour you have known for decades is on the tip of your tongue. When you are asked a question in a meeting, you realise you didn't hear anything said in the last two minutes. Then the question comes: "Is something wrong with me? Or is dementia starting?" Forgetfulness from stress is an experience adults commonly have, especially during intense and overloaded periods, and one they often fear in silence. In this article I explain how stress affects memory and attention, the signs that distinguish it from dementia and ways of coping with the feeling that "my mind is elsewhere".
What Is Forgetfulness from Stress?
Forgetfulness from stress is not a medical diagnosis; it is an everyday expression describing temporary lapses in memory and attention during periods of intense stress, anxiety or fatigue. People usually describe it like this: "My head feels as if it's stuffed with cotton wool", "I don't understand what I read, I read the same paragraph three times", "I forget what I was going to say."
What is actually disrupted here is often not memory itself but attention. To be able to remember a piece of information, you first have to register it. And registering it requires attention. While your mind is occupied with things like the rent payment, a sick relative, tension at work or a talk you have to give tomorrow, the information about where you put the keys may never have been registered at all. In other words, you never actually learnt the thing you think you have forgotten.
In cognitive psychology there is a concept called "working memory": the temporary space where the mind holds and works on information at that moment. The capacity of this space is limited. When worries, anxious thoughts and the to-do list fill this space, there is no room left for new information.
How Does Stress Affect Memory and Attention?
In the short term, stress hormones can help us remember certain kinds of information; this is why we remember a dangerous moment in detail. But when stress lasts a long time, the picture changes. Chronic stress can adversely affect the functioning of brain regions that play an important role in learning and memory. There are also some everyday routes:
- Lack of sleep: What is learnt during the day is consolidated during sleep. Sleep broken by anxiety also affects the next day's memory.
- Constant scanning: The anxious mind scans its surroundings as if looking for danger and finds it hard to fix attention on one place.
- Overthinking: As the mind circles around the same topics, fewer resources are left for the present moment.
- Multitasking: Trying to reply to messages, not forget the food on the hob and check a child's homework all at once breaks attention into pieces.
- Emotional load: Sadness, grief or anger also use up mental resources.
In short, stress throws the mind's "desk" into disarray. When the desk is messy it is hard to find anything; but that doesn't mean the desk is broken.
Fear of Dementia: Signs That Separate Forgetfulness from Stress and Dementia
The greatest fear of many adults experiencing forgetfulness is dementia. Especially those with a family history of dementia, or those who have witnessed a mother's or father's illness, may be gripped by the same fear with every lapse. This fear is understandable; but there are often clear differences between the forgetfulness created by stress and anxiety and dementia. The comparison below is not a diagnostic tool, only a general framework:
- Awareness: In stress-related forgetfulness, the person is aware of their forgetfulness and is even very troubled by it. In the later stages of dementia, the person is often unaware of the problem; it is usually those around them who notice it.
- Recall with a prompt: A stressed person usually remembers what they forgot when given a cue. When told "remember, we talked about it on Tuesday", they say "Oh, yes."
- What is forgotten: Forgetting where you put the keys is one thing; forgetting what keys are for is another. Getting lost on a familiar route, being completely unable to remember a recipe you have made for years, or not recognising familiar people are signs that call for more attention.
- Fluctuation: Stress-related forgetfulness decreases noticeably on days of good sleep and calm. In dementia, the course generally progresses slowly over time.
- Link with the period of life: Forgetfulness described as "I've been really bad this year" and coinciding with a heavily loaded period of life is more likely to be stress-related.
These signs may help you make a distinction, but they are not sufficient for a definite judgement. If your worry persists, consulting a neurologist or psychiatrist will be far more reassuring than living with the fear.
Forgetfulness may have other causes too
Apart from stress, thyroid problems, certain vitamin deficiencies, sleep apnoea, some medications, changes during the menopause, alcohol use and depression can also cause forgetfulness. Forgetfulness can be particularly marked in depression and is sometimes confused with dementia; for details, you can read the article on forgetfulness in depression. Poor concentration that has continued since childhood, constantly losing things and leaving tasks unfinished may require assessment for adult attention deficit; the article on ADHD symptoms may give you an idea.
The Everyday Feeling That "My Mind Is Elsewhere"
Many adults in Turkey lead lives that carry a very heavy mental load. On the one hand, work; on the other, children preparing for the LGS or YKS (Turkey's national high-school and university entrance exams), school bus times, parents' evenings; and on top of that, elderly parents' doctor's appointments and medications, bill days and the messages piling up in the family WhatsApp group. Much of this load is invisible management work and requires the mind to run constantly in the background.
Imagine you are a forty-five-year-old teacher. This term you have your own class's exam preparation, your daughter is sitting the university entrance exam, and your father recently had an operation. One morning at school, while teaching, you can't remember the word you were about to write on the board, and on the way home that day there is a fear inside you. This experience is very familiar, and it usually shows not that your brain is breaking down but that the load you are carrying is straining your capacity.
There is also a situation many people described after the 6 February 2023 earthquakes: "Since the earthquake I can't concentrate on anything, it's as if my mind is foggy." Attention and memory problems following traumatic events can be a sign that the brain is still in alarm mode, and they usually ease as a sense of safety is rebuilt.
Anxiety that grows with every lapse
When forgetfulness is noticed, most people start monitoring themselves. Every lapse is recorded like a piece of evidence, every time a name slips away it creates a big alarm. This constant self-monitoring also becomes a new load that splits attention and increases forgetfulness. This creates the cycle of "forgetfulness – fear – more forgetfulness". In this cycle, some people do online memory tests one after another and keep asking their partner or children, "Did I already tell you this?" Every test and every question brings brief relief, but it starts again the next day, just like reassurance-seeking in health anxiety.
What Can You Do to Cope with Forgetfulness from Stress?
Move things out of your head
Everything you try to keep in mind takes up space in your working memory. Write your to-dos, appointments and payments in a notebook or in a single list on your phone. The aim is not to remember everything, but to hand the burden of remembering over from the mind to paper. Don't see this as a weakness; it is a smart way of saving mental energy for more important tasks.
Give your belongings a fixed place
Set aside a fixed bowl or shelf by the front door for your keys, wallet, glasses and phone. Make it a habit to leave things there as soon as you come in. This small arrangement noticeably reduces the frantic searching during the day and the stress of "I've lost it again".
Return to one task at a time
As far as possible, focus on one task at a time. Turn your phone face down while writing an email, don't look at messages while cooking, move away from the screen while someone is talking. When attention is not divided, registration is healthier too.
Slow down at the moment of registering
If you want to remember where you put something important, pause for a second as you put it down and say to yourself, out loud or silently: "I put the passport in the bedroom drawer." This simple step turns an action on autopilot into a conscious record.
Reduce notifications
Every notification that comes to your phone during the day is a small call that pulls your attention away from where it is. Each time it is pulled away, it takes time for the mind to return to the previous task, and the half-finished thoughts are lost in the meantime. Turning off notifications from news apps, shopping sites and busy groups, and checking messages in batches at certain times of day, noticeably reduces the noise that splits attention. Many people start saying "my head is a bit clearer" a few days after trying this. This does not mean your memory has suddenly become stronger; it means you have opened up quiet moments in which your mind can register things.
Protect sleep and breaks
A good night's sleep is more effective than many memory exercises. During the day, too, taking short breaks rather than working for long stretches without a pause gives the mind the chance to settle information.
Set aside time for worry
When worries circle in the mind all day, they constantly split attention. Writing your worries down for fifteen or twenty minutes at a set time each day, and postponing the worries that come up during the day to that time, can ease the mind a little.
Be kind to yourself
When you forget something, instead of saying "Am I stupid or what?", try saying "I'm very overloaded at the moment, that's why." Self-criticism increases anxiety, and anxiety increases forgetfulness. If your loved ones make fun of your forgetfulness, explaining to them at a calm moment how it affects you can also help.
When Should You Seek Professional Support?
It is important to see a doctor in the following situations:
- If forgetfulness is getting progressively worse and makes it difficult for you to carry out daily tasks,
- If you get lost in familiar places or mix up familiar people,
- If your loved ones say they have noticed a marked change in you,
- If difficulty speaking, personality change, headache or balance problems accompany it.
In the case of symptoms such as sudden speech disturbance, drooping of the face or weakness in an arm or leg, call 112 (emergency services) without waiting.
After a medical assessment, if the forgetfulness is thought to be related to stress, anxiety or depression, working with a mental health professional is helpful. You may consider getting support especially if fear of dementia occupies your day, if you constantly test yourself, or if there are also changes in your sleep, appetite and capacity to enjoy things.
How Is Stress-Related Forgetfulness Addressed in Therapy?
In therapy, the work focuses not so much on the forgetfulness itself as on the stress and anxiety feeding it. First, the person's load, sleep pattern, worries and daily functioning are assessed together. In cognitive behavioural therapy, thoughts such as "If I forget something, everything will be ruined" or "Since I'm forgetting things, dementia must be starting" are examined and evaluated together with the evidence.
Behaviours such as constantly testing oneself, recording every lapse or searching for symptoms online are recognised and reduced. Practical tools such as worry time, attention exercises, relaxation skills and daily planning become part of the process. Sometimes the issue is the person's expectation of carrying everything alone and never letting anything slip; softening these expectations opens up real breathing space for the mind.
Forgetfulness is very often the sign not of a mind that is breaking down, but of a mind that is overloaded.
If you would like to plan this process according to your own circumstances, you can find information on the individual therapy page.
Frequently Asked Questions
Does forgetfulness from stress go away?
In most cases, as stress decreases, sleep improves and the mental load lightens, forgetfulness also decreases noticeably. However, if stress has been going on for a long time, recovery may also take time. If forgetfulness continues even though stress has decreased, a medical assessment is needed.
Is forgetfulness in your forties normal?
With age, some difficulty remembering names or multitasking can be considered normal to a degree; these years are also when the load of work and family is at its heaviest. Still, if forgetfulness increases markedly or makes your daily life difficult, consulting a doctor is the healthiest course.
Do memory exercises help with forgetfulness?
Activities such as crosswords and word games can be enjoyable for keeping the mind active. But in stress-related forgetfulness, what really works is sleep, stress management and directing attention to a single task. It makes more sense to reduce the mind's load first, and then exercise it.
Can a psychologist help with my forgetfulness?
If your forgetfulness is related to stress, anxiety or depression, psychological support can make an important difference. A psychologist does not make a medical diagnosis; therefore it is recommended that the necessary medical assessment is carried out first. If the feeling that "my mind is elsewhere" has been with you for a long time, talking about it with a professional may be the first step towards giving your mind room to breathe.
