Early Signs of Dementia: A Practical Checklist for Families

Worrying about dementia is one of the most common concerns among older adults and their adult children. And the worry itself can make you notice every forgotten name and misplaced key.

Most forgetfulness is normal. Some isn’t. Knowing the difference — and what to do if you suspect a real problem — is one of the most important things families can learn.

Normal aging vs. early dementia: the key difference

The difference isn’t whether memory lapses happen. They happen to everyone.

The difference is the pattern, persistence, and impact on daily life.

Normal aging	Possible early dementia
Occasionally forgetting a name but remembering it later	Forgetting recently learned information and not recalling it later
Sometimes needing help with technology	Difficulty following familiar routines or recipes
Making a bad decision once in a while	Consistently poor judgment with money, hygiene, or safety
Missing a monthly bill once	Inability to manage a budget or pay recurring bills
Forgetting what day it is but figuring it out	Losing track of dates, seasons, or the passage of time
Sometimes struggling for the right word	Stopping mid-conversation with no idea how to continue
Misplacing things and retracing steps to find them	Putting items in unusual places (keys in the freezer) and not being able to retrace steps
Mood changes with a specific event	Personality changes, confusion, suspicion, or withdrawal without clear cause

If changes happen occasionally and don’t affect daily life, they’re more likely normal aging. If they happen more frequently, get worse over time, and start to interfere with work, driving, finances, or relationships, they warrant evaluation.

The 10 most common early signs

The Alzheimer’s Association and National Institute on Aging identify these warning signs. Most people with early dementia show several of them, and they tend to be noticeable to family members even when the person experiencing them isn’t aware.

1. Memory loss that disrupts daily life

The classic early sign. Forgetting recently learned information, important dates, or events; asking the same question repeatedly; increasingly relying on memory aids (notes, reminders) for things that used to be handled without thinking.

Key distinction: occasionally forgetting a name and then remembering it is normal. Forgetting a conversation you had this morning and not recalling it later is not.

2. Challenges in planning or solving problems

Difficulty following a familiar recipe, managing monthly bills, or keeping track of a checkbook. Trouble concentrating that takes much longer than it used to.

3. Difficulty completing familiar tasks

Forgetting the rules of a favorite game, struggling to drive to a familiar location, or having trouble with the steps of a routine task like making coffee.

4. Confusion with time or place

Losing track of dates, seasons, or the passage of time. Forgetting where you are or how you got there.

5. Trouble understanding visual images and spatial relationships

Difficulty reading, judging distance, or determining color or contrast. Can affect driving safety and the ability to navigate familiar environments.

6. New problems with words in speaking or writing

Stopping mid-sentence with no idea how to continue. Struggling with vocabulary (calling a watch a “hand-clock”). Repeating the same stories or phrases.

7. Misplacing things and losing the ability to retrace steps

Putting items in unusual places (the car keys in the bathroom cabinet) and being unable to find them by thinking through where they might be.

8. Decreased or poor judgment

Making uncharacteristic decisions about money, hygiene, or safety. Falling for scams that the person would have seen through before. Neglecting personal cleanliness or grooming.

9. Withdrawal from work or social activities

Pulling back from hobbies, social groups, or work projects because they’re harder to follow. Avoiding social situations due to the changes the person is noticing.

10. Changes in mood and personality

Becoming confused, suspicious, anxious, fearful, or dependent on a family member. Mood swings that seem out of character. Becoming upset in situations where the person used to be comfortable.

What to do if you’re concerned

Step 1: Talk to a doctor

Schedule an appointment with a primary care physician or geriatrician. Bring a written list of specific changes you’ve observed, when they started, and how they’ve progressed. The doctor will likely:

• Review medications (some can cause dementia-like symptoms)
• Order blood tests to check for reversible causes (B12, thyroid, infections)
• Conduct cognitive screening tests
• Possibly refer to a neurologist for more detailed evaluation

The reversible causes are important to rule out. Some conditions that mimic dementia — depression, medication side effects, B12 deficiency, thyroid problems, infections, normal pressure hydrocephalus — can be treated.

Step 2: Don’t delay

Earlier diagnosis matters for several reasons:

• Some causes of dementia are treatable, and early treatment is more effective
• Medications for Alzheimer’s disease work best in the early stages
• Earlier diagnosis allows the person to participate in planning their own care
• Clinical trials are more accessible in early stages
• Families have more time to make legal, financial, and care arrangements

Step 3: Get a thorough workup

A proper dementia evaluation includes:

• Detailed medical history
• Cognitive and memory testing
• Physical and neurological exam
• Blood tests to rule out reversible causes
• Sometimes brain imaging (MRI or CT)
• Sometimes specialized tests (PET scan, spinal fluid analysis)

Don’t accept “just normal aging” as a diagnosis without a proper evaluation. If the primary care doctor is dismissive, ask for a referral to a geriatrician or neurologist.

Less common but worth knowing

Not all dementia is Alzheimer’s disease. Other common forms have different patterns and may respond to different treatments:

• Vascular dementia: caused by reduced blood flow to the brain; often follows a stroke or series of small strokes; progression tends to be stepwise rather than gradual
• Lewy body dementia: features visual hallucinations, movement problems (similar to Parkinson’s), and sleep disturbances; often misdiagnosed as Alzheimer’s or Parkinson’s
• Frontotemporal dementia: affects personality, behavior, and language more than memory; often begins at a younger age (50s–60s)
• Parkinson’s disease dementia: develops in many people with advanced Parkinson’s

Each has different implications for treatment and care planning, which is another reason a thorough evaluation matters.

For families: how to support

If someone you love is showing early signs, a few things help:

• Be patient: avoid correcting every mistake; focus on what they can still do
• Don’t take over completely: staying engaged in daily activities preserves function longer
• Create routines: structure reduces the cognitive load
• Use memory aids together: shared calendars, posted schedules, labeled drawers
• Plan for the future: legal, financial, and care planning should happen early, when the person can still participate
• Get support for yourself: caregiver burnout is a real risk; local Alzheimer’s Association chapters and Area Agencies on Aging offer resources

The honest take

Dementia is frightening, and the most common reaction to early signs is denial — both for the person experiencing them and for the family. The natural impulse is to find another explanation: stress, sleep, medication changes, normal aging.

Sometimes that’s correct. But when it isn’t, the earlier you get a real evaluation, the more options you have. The hard, brave thing is to look at the signs honestly and act on them — for yourself or for someone you love.
