Worrying You Have Dementia Yourself: A Guide for Caregivers

If you're a family caregiver and you've started forgetting things, you're not alone in worrying it might be dementia. This article helps you understand why stress, sleep loss, and overwhelm can mimic memory problems, and gives you concrete steps to sort out what's normal from what needs a doctor's visit. You'll find real phrases to use, tools to reduce your own stress, and clear guidance on when to seek help. There are many reversible causes for what you're feeling, and there are things you can do right now to feel more in control.

Key points

  • Worrying that you have dementia is actually a sign that you likely don't — people with dementia often don't realize they have a problem.
  • Stress, sleep deprivation, and depression are the most common causes of forgetfulness in caregivers, and they are reversible.
  • Normal forgetfulness (misplacing keys, forgetting a name) does not disrupt daily life; dementia does.
  • There are many reversible causes of memory problems, including vitamin deficiencies, thyroid issues, and sleep apnea — see a doctor to rule these out.
  • Prioritizing your own sleep, nutrition, and exercise is not selfish — it's essential for your brain health and your ability to care for your loved one.
  • You are not alone in this fear. Talk to other caregivers, join a support group, and be kind to yourself.

Why Caregivers Often Fear They Have Dementia

When you're caring for someone with dementia, it's easy to start noticing your own forgetfulness and wonder if it's happening to you too. Misplacing your keys, forgetting why you walked into a room, or struggling to recall a name can feel terrifying. But for the most part, these are signs of being busy, stressed, and overwhelmed — not dementia. As one expert notes, 'for the most part that is just normal human behavior and it's occurring because you're busy, you're stressed, you're overwhelmed' (source 5). The very act of worrying about your memory is actually a clue that it's likely not dementia; people with true dementia often don't realize they're having problems (source 5).

The Real Culprits: Stress, Sleep, and Depression

Caregiving is exhausting, and that exhaustion directly affects your brain. Sleep deprivation, poor nutrition, and chronic stress can all make it harder to think clearly. As one expert asks, 'Do you think someone who has been sleep deprived or who has been getting poor quality of sleep for a while thinks as clearly and as good as they're able to? No way' (source 4). Depression is also extremely common in caregivers and is actually the number one cause of memory-like symptoms in people over 60 (source 5). When you're depressed, your brain is working harder just to get through the day, and that can look like forgetfulness or confusion.

What's Normal Forgetfulness vs. a Real Problem

The key difference between normal forgetfulness and dementia is whether it disrupts your daily life. Forgetting a name occasionally, misplacing your phone, or walking into a room and forgetting why are all normal, especially when you're stressed. But if you're missing appointments, getting lost in familiar places, having trouble managing finances, or if other people are starting to notice and comment, that's a sign to get checked (sources 2, 9). Dementia is progressive and gets worse over time, while stress-related forgetfulness tends to improve when you rest or reduce your load (source 25).

Other Reversible Causes of Memory Problems

Many things can cause dementia-like symptoms that are not dementia at all. These include vitamin deficiencies (especially B12 and D), thyroid problems, sleep apnea, medication side effects, and even a brain tumor that might be operable (sources 2, 19). That's why it's so important to see a doctor rather than just worrying. A thorough evaluation can rule out these reversible causes and give you real answers. As one expert says, 'there are up to 36 different reasons factors toxicity, blood sugar, inflammation, diabetes, things that we eat, gluten, lots of different reasons why people have changes in their thinking processes' (source 21).

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

  1. Start a simple memory log. For one week, write down every time you notice a memory slip, noting the time, what you forgot, and what was happening right before. This helps you see patterns and gives your doctor useful information.

  2. Prioritize one night of good sleep this week. Go to bed 30 minutes earlier, turn off screens an hour before bed, and if you can't sleep through the night, take a 20-minute daytime nap.

  3. Take three 10-minute walks this week to increase blood flow to your brain. Do them outside in daylight if possible to also boost your mood.

  4. Schedule a check-up with your primary care doctor. Tell them you're a caregiver with memory issues and ask them to test for reversible causes like vitamin B12 deficiency, thyroid problems, sleep apnea, and to review all medications (including over-the-counter) for side effects that affect memory.

  5. Talk to someone you trust — a friend, family member, or caregiver support group — about your worry. Saying it out loud reduces anxiety, and you can also ask if they've noticed any changes in you.

  6. Eat real meals and drink 6-8 glasses of water daily. Keep protein-rich foods like cheese sticks, nuts, or yogurt nearby. Dehydration alone can mimic memory problems.

What not to do

  • Do not assume every forgotten thing is dementia. Catastrophizing increases anxiety, which worsens memory. Remind yourself that stress, lack of sleep, and overwhelm are far more likely causes.

  • Do not skip your own health appointments. Many caregivers avoid check-ups, leading to undiagnosed conditions that affect memory. Treat your own check-up as part of your caregiving duties.

  • Do not compare yourself to the person you're caring for. Their dementia is a progressive brain disease; your forgetfulness is likely due to exhaustion and stress. Focus on what you can control: sleep, nutrition, and stress.

  • Do not try to 'power through' without rest. Pushing yourself when exhausted makes memory worse. Build in short breaks, even five minutes of sitting quietly.

Practical tools

  • The 'Is This Dementia?' Self-Check

    Ask yourself: (1) Is this forgetfulness disrupting everyday tasks like cooking, shopping, or managing money? (2) Have others noticed and commented? (3) Is it getting worse over time? If all three are 'no,' it's likely stress; if any are 'yes,' see a doctor.

  • The 3-Breath Reset for Memory Anxiety

    When you catch yourself worrying about memory, stop and take three slow breaths. On each exhale, say silently: 'This is stress. I am safe. I can handle this.' This lowers stress hormones and helps you think more clearly.

  • The Doctor Visit Prep Sheet

    Before your appointment, write down: (1) Your memory log, (2) A list of all medications and supplements, (3) Other symptoms like fatigue or mood changes, and (4) The question: 'Could this be caused by stress, depression, sleep apnea, or a vitamin deficiency?'

  • The Support Group Connection

    Find an online or in-person caregiver support group. Hearing others describe the same fears and forgetfulness helps you realize you're not alone and provides a judgment-free place to share your worry.

Discuss with your clinician

Ask your doctor: 'Could my memory problems be caused by a vitamin B12 or D deficiency, and should I have my levels checked?'

Ask your doctor: 'Could my medications (including over-the-counter) be causing memory issues as a side effect?'

Ask your doctor: 'Should I be screened for sleep apnea, which can cause memory and concentration problems?'

Ask your doctor: 'Could my thyroid function be affecting my memory?'

If you have a family history of early-onset dementia, ask your doctor: 'Should I consider genetic counseling or testing?'

If you are experiencing depression or anxiety, ask your doctor: 'Could treating my mood improve my memory?'
