More persistent communication problems can be different.
A person may have increasing difficulty following or joining conversations, repeatedly lose their train of thought, repeat themselves, or struggle to name familiar objects.
Language difficulties are among the recognized symptoms that can occur with dementia and Alzheimer’s disease.
7. Misplacing Things in Unusual Places
We’ve all misplaced our phone, glasses, or keys.
A potentially concerning change is repeatedly putting everyday objects in unusual places and then becoming unable to retrace your steps to find them.
As cognitive problems progress, a person may sometimes become convinced that someone else has moved or taken the missing object.
8. Changes in Judgment or Decision-Making
Dementia can affect more than memory.
Changes in judgment may cause someone who was previously careful with money to make unusual financial decisions or become more vulnerable to scams.
There may also be noticeable changes in personal care or everyday safety
decisions.
One bad decision isn’t evidence of dementia. What matters is a persistent change from the person’s previous behavior and abilities.
9. Withdrawal From Social Activities
A person experiencing memory or communication difficulties may gradually withdraw from hobbies, work projects, sports, family gatherings, or social activities.
Sometimes this happens because keeping up with conversations or familiar activities has become frustrating or difficult.
Social withdrawal can also be caused by depression, anxiety, hearing difficulties, stress, and many other factors, so professional assessment can be important.
10. Changes in Mood or Personality
Family and friends may sometimes notice behavioral changes.
A person may become unusually anxious, fearful, suspicious, confused, withdrawn, or easily upset, particularly when outside their usual routine.
Mood and personality changes can have numerous causes, but persistent changes occurring alongside memory or thinking difficulties may deserve medical attention.
Normal Aging vs. Possible Dementia
This distinction is extremely important.
Getting older
does not mean that every forgotten name or misplaced object is a warning sign of dementia.
For example, forgetting an appointment but remembering it later can happen during normal aging. Repeatedly forgetting important information and becoming unable to manage activities that were previously routine is more concerning.
Similarly, occasionally choosing the wrong word is different from developing persistent difficulty participating in conversations.
The Alzheimer’s Association emphasizes that memory loss disrupting daily life is not considered a typical part of aging.
Having These Symptoms Doesn’t Automatically Mean Dementia
This is perhaps the most important point.
Experiencing one or several symptoms on this list does not prove that someone has dementia.
Cognitive or memory changes can have different causes, and some may be treatable.
The appropriate way to determine what’s happening is through professional medical evaluation rather than an online checklist.
Different types of dementia can also produce different patterns of symptoms.
When Should You Talk to a Doctor?
Consider seeking medical advice when memory, thinking, language, judgment, or behavioral changes are:
New, persistent, progressively worsening, or interfering with everyday activities.
A healthcare professional can investigate possible causes and determine whether additional assessment or testing is appropriate.
The Alzheimer’s Association recommends scheduling a medical appointment when warning signs are noticed rather than ignoring them.
Why Early Evaluation Matters
Seeking medical advice doesn’t automatically mean receiving a dementia diagnosis.
Instead, evaluation can help determine what is causing the changes.
If Alzheimer’s or another form of dementia is responsible, identifying the condition earlier can provide more time to discuss treatment options, support, lifestyle considerations, and plans for the future.
The Bottom Line
Dementia can begin with subtle changes.
Memory loss is one of the best-known warning signs, but difficulties involving language, planning, judgment, navigation, everyday activities, mood, and personality may also occur.
The key
isn’t to panic over occasional forgetfulness.
Instead, pay attention to patterns of change that persist, worsen, or begin interfering with normal daily life.
If you’re concerned about changes in yourself or someone close to you, a conversation with a qualified healthcare professional is the appropriate next step.
