Everyday Forgetfulness: When to Worry

Misplacing keys or blanking on a name is usually a normal part of aging; here is how to tell everyday forgetfulness from warning signs of something more serious, and when to talk with a doctor.

Last reviewed: October 2026

You walk into the kitchen and can't remember why. The name of an old friend's husband sits on the tip of your tongue. Your glasses turn up on top of your head. Moments like these can be unsettling, especially if a parent had dementia. But most of the time, they are just part of being human—and part of getting older.

This article explains what kinds of forgetting are typical, which signs deserve a closer look, and what to do if you're worried.

Forgetting is normal at every age

Everyone forgets things. As Mayo Clinic puts it, perhaps you misplace your car keys or forget the name of someone you just met. The National Institute on Aging (NIA) notes that it's normal to forget things once in a while at any age.

With age, the brain changes like the rest of the body. According to the NIA, many older adults notice that:

They don't remember information as well as they once did.
Recall takes longer. The name comes back, just not right away.
Learning something new takes longer.
They occasionally misplace things or forget to pay a bill.

The NIA calls this mild, age-related forgetfulness. Mayo Clinic adds that typical age-related memory changes are generally manageable and don't affect your ability to work, live independently or keep up a social life. For most people, these changes don't get much worse over time. Learn more in Normal Aging vs. Memory Problems.

Normal aging vs. possible warning signs

The key question isn't whether you forget, but how much it disrupts daily life. The NIA and the Alzheimer's Association offer helpful comparisons:

Typical age-related change	Possible sign of a problem
Making a bad decision once in a while	Making poor judgments and decisions much of the time
Missing a monthly payment	Trouble managing monthly bills or a budget
Forgetting which day it is and remembering it later	Losing track of the date or the season
Sometimes forgetting which word to use	Trouble having a conversation
Losing things from time to time and retracing your steps to find them	Misplacing things often, in odd places, and being unable to find them
Forgetting a name or appointment, then remembering it later	Forgetting recently learned information or asking the same question repeatedly

Notice a pattern in the left column: with typical forgetting, the information often comes back later. It's also worth listening when family or friends notice changes. Mayo Clinic points out that some people aren't aware of how much they've adapted to memory loss, and that loved ones sometimes quietly make up for it. See Anosognosia (Lack of Awareness).

Signs it's time to talk with a doctor

The NIA suggests seeing a doctor if you or a loved one are:

Asking the same questions over and over
Getting lost in places you used to know well
Having trouble following recipes or directions
Becoming more confused about time, people and places
Not taking care of yourself—eating poorly, not bathing or behaving unsafely

Mayo Clinic adds signs such as forgetting common words, mixing up words (saying "bed" instead of "table"), taking longer to finish familiar tasks, putting items in odd places (such as a wallet in a kitchen drawer) and mood or behavior changes for no clear reason.

The Alzheimer's Association lists 10 early warning signs, including memory loss that disrupts daily life, trouble planning or solving problems, difficulty with familiar tasks, new problems with words, poor judgment and withdrawal from work or social activities. See 10 Early Warning Signs of Alzheimer's and Dementia.

Something in between: mild cognitive impairment

Some people have more memory or thinking problems than others their age but can still take care of themselves and handle daily tasks. This is called mild cognitive impairment (MCI). The NIA notes MCI can be an early sign of Alzheimer's disease, but not everyone with MCI develops Alzheimer's. See Mild Cognitive Impairment (MCI).

Many memory problems have treatable causes

Before assuming the worst, remember that forgetfulness can come from things that have nothing to do with dementia. According to the NIA and Mayo Clinic, causes include:

Medication side effects or combinations of medicines—see Medications That Can Affect Memory
Depression, anxiety and stress—see Depression and Memory ("Pseudodementia") and Stress, Anxiety and Memory
Poor sleep or untreated sleep apnea—see Sleep and Memory
Low vitamin B12—see Vitamin B12 Deficiency and Memory
Thyroid, kidney or liver problems
Alcohol or drug misuse
Head injury, even a minor one
Infections, blood clots or tumors in the brain

Big life changes matter too. The NIA notes that retirement or the death of a spouse can leave people sad, lonely or worried, and that this can cause temporary forgetfulness. If memory problems last more than a few weeks, talk with your doctor. See Reversible Causes of Memory Problems.

Everyday tips that help

The NIA suggests simple habits to cope with normal forgetfulness and support brain health:

Keep important items in the same place every day—wallet or purse, keys, phone and glasses.
Follow a daily routine.
Use to-do lists, calendars and notes. See Memory Aids and Tools.
Learn a new skill, and stay involved in activities that engage both mind and body.
Spend time with friends and family, or volunteer.
Get enough sleep—generally seven to eight hours a night.
Exercise and eat well, and prevent or control high blood pressure. See Blood Pressure and the Brain.
Limit alcohol, and get help if you feel depressed for weeks at a time.

For more techniques, see How to Improve Your Memory. The NIA also urges caution about pills, supplements and brain games that promise to sharpen memory or prevent dementia. They may be unsafe, a waste of money or both. Check with your doctor first.

When to see a doctor

If memory changes are noticeable, getting worse or affecting daily life, make an appointment. Mayo Clinic suggests bringing a family member or friend who can share what they've noticed, and being ready to discuss:

When the symptoms began
All medicines and supplements you take, including any new ones
How much alcohol you drink
Recent falls, head injuries or illnesses
Mood, stress or major life changes

Your doctor may do a physical exam, memory tests, blood tests or brain imaging, and may refer you to a specialist such as a neurologist or geriatrician. See Getting a Diagnosis and Cognitive Screening Tests (MMSE, MoCA).

Getting checked can bring real relief. Mayo Clinic notes that finding a reversible cause means you can get the right treatment, and an early diagnosis of a condition like MCI or Alzheimer's gives you time to start treatment, learn about it and plan ahead.
