Cognitive Changes: Normal Aging vs. Warning Signs

Distinguishing normal aging from something that warrants medical attention can be genuinely difficult — here’s a general framework, though only a doctor can properly evaluate a specific situation.

Is it normal to occasionally forget names or misplace things?

Yes - occasional forgetfulness, like briefly forgetting a name or misplacing keys, is common and generally considered a normal part of aging. Other generally normal changes include:

• Occasionally forgetting a name, then recalling it later
• Briefly misplacing items like keys or glasses
• Needing a bit more time to process new information
• Occasionally forgetting an appointment, but remembering it later

What are signs that go beyond typical aging?

• Difficulty completing familiar, routine tasks
• Confusion about time, date, or place
• Trouble following or joining conversations
• Noticeable changes in judgment or decision-making
• Repeating questions or stories within a short period
• Getting lost in familiar places

Only a doctor can properly evaluate what's actually happening.

Does this mean my parent has dementia?

Not necessarily - noticing some of these signs doesn’t mean a specific diagnosis is certain. Several conditions, including some treatable ones like medication side effects, depression, or thyroid issues, can cause similar symptoms. Only a doctor can properly evaluate what’s actually happening.

If dementia is diagnosed, it helps to know what lies ahead; see our guide on how dementia ends and what families can expect.

For a later-stage challenge many families face, see our guide on what to do when a parent with dementia no longer recognizes you.

What should I do if I notice concerning signs?

Bring specific examples to a doctor’s appointment - what you’ve noticed, how often, and any changes over time - rather than trying to determine the cause yourself. This gives the doctor much more useful information to work with than a general sense that “something seems off.”

This is general educational information, not a diagnostic tool. Please consult a doctor for evaluation of any specific concerns.
