That means older adults and their families should pay attention to persistent changes rather than dismissing everything as “just getting older.”
Doing so can delay an evaluation that might identify the actual cause.
## Memory Problems Can Have Other Causes
Perhaps the most important caution is this:
**These signs do not prove that someone has dementia.**
Memory problems can occur for many reasons.
Stress can interfere with concentration.
Poor sleep can affect memory.
Depression and anxiety can affect thinking.
Certain medications can contribute to cognitive symptoms.
Other medical conditions can also produce changes in memory or behavior.
The NHS specifically advises against trying to diagnose the cause of memory loss on your own.
That is why a medical evaluation is so important.
A healthcare professional can consider the person’s symptoms, medical history, medications, and progression over time and determine whether further assessment is needed.
## When Should You Talk to a Doctor?
If memory or thinking problems are affecting everyday life, it is reasonable to make an appointment.
It can be helpful to write down specific examples before the visit.
Instead of saying, “Their memory is getting worse,” record what actually happened.
For example:
“They forgot an appointment they had written down.”
“They asked the same question several times.”
“They became confused while driving a familiar route.”
