One of the strangest things about dementia is that memory doesn't simply disappear from newest to oldest in a perfectly orderly fashion. A person may have no recollection of what they ate for lunch, who visited that morning or what happened yesterday, yet remember the name of a childhood neighbour, the layout of a house they lived in sixty years ago, the words to an old song or some obscure detail from their working life.
That raises an interesting question.
Could spending time talking about the memories that remain actually help someone's self-esteem and sense of identity?
Researchers have been exploring versions of that question for decades.
It's Called Reminiscence Therapy
There is an established approach in dementia care called reminiscence therapy.
At its simplest, it involves encouraging someone to talk about experiences from their past. Photographs, familiar music, household objects, old neighbourhoods, family stories, weddings, jobs, holidays, recipes and childhood experiences can all provide starting points.
Importantly, the objective isn't necessarily to improve memory.
It isn't a quiz.
Instead, reminiscence can provide access to parts of a person's life and identity that remain available even as recent memory becomes increasingly unreliable.
A Cochrane review examined 22 studies involving 1,972 people with dementia. Researchers looked at outcomes including quality of life, cognition, communication, mood and behaviour. The effects varied depending upon how and where reminiscence was used, but researchers found some benefits, including improvements in communication and some measures of quality of life.

A later systematic review and meta-analysis examined 29 studies involving 3,102 people with dementia. Reminiscence therapy was associated with improved cognitive function and quality of life, as well as reductions in depression and neuropsychiatric symptoms. The researchers concluded that reminiscence may be a useful non-drug intervention, particularly in nursing homes and other long-term-care environments.

More recent research continues to find promising results. A 2025 systematic review and meta-analysis examined 26 randomized controlled trials involving 2,766 people with cognitive impairment. Reminiscence therapy was associated with improvements in cognitive function, depressive symptoms and quality of life, although it did not significantly improve every outcome examined. 2025 systematic review and meta-analysis
What About Self-Esteem?
This may be one of the most interesting aspects of reminiscence.
Think about what progressive memory loss can do to someone's sense of competence.
You don't remember who brought you coffee this morning.
You don't remember what you ate for lunch.
Someone tells you that you had a visitor yesterday and you have absolutely no recollection of it.
People increasingly remind you where things are, what day it is, what you're supposed to be doing and what happens next.
Without anyone intending it, everyday life can become a continual demonstration of what you can no longer do.
Now change the conversation.
What was the house where you grew up like?
What did your family grow in the garden?
What did you do at your first job?
How did people celebrate Christmas when you were a child?
What was your mother famous for cooking?
Who was the funniest person in your family?
Suddenly the person with dementia may know things nobody else in the room knows.
That is a very different psychological position.
Research into reminiscence among older adults without dementia has specifically examined this dimension. A systematic review involving 31 studies and 1,829 older adults found reductions in depressive symptoms and improvements in life satisfaction. Researchers also found positive effects involving self-esteem, psychological well-being and happiness, although the self-esteem studies weren't sufficiently comparable to combine statistically.

Another systematic review and meta-analysis involving 27 studies and 1,755 older adults found significant improvements in depression and life satisfaction. Studies examining self-esteem also reported improvement, although there was considerable variation among the studies. 2023 systematic review and meta-analysis
None of this means reminiscing is a magic treatment for dementia or that every person will respond the same way.
But it suggests something worth considering:
Perhaps remembering isn't only about memory. It can also be about identity.
Don't Turn Reminiscing Into a Test
There is an important difference between inviting someone to reminisce and testing their memory.
“Do you remember who this is?”
“Don't you remember going there?”
“What was your neighbour's name?”
“Remember when we did that?”
Even when asked lovingly, these questions can inadvertently create another opportunity to discover something has disappeared.
An alternative is simply to open a door.
“Tell me about the house you grew up in.”
“What did you do for fun when you were young?”
“What did your dad do for a living?”
“What did you grow in your garden?”
“What was your first car?”
“What was dating like back then?”
And perhaps some of the best questions are those for which the person asking genuinely doesn't know the answer.
Something important changes in that interaction.
The person with dementia isn't being helped to remember.
They're teaching someone else.
They're the person with the knowledge.
They're the storyteller.
They're the expert.
For someone who increasingly has other people telling them where to go, what they've forgotten, when their medication is coming and what happens next, having something valuable to give another person may matter enormously.
Follow the Feeling, Not the Facts
Reminiscence doesn't need to become historical fact-checking either.
A story told about something that happened fifty years ago may contain inaccuracies. Details may become mixed together. Two different events may merge. Names may be wrong.
Unless the mistake actually matters, correcting it can defeat the purpose.
The interesting question isn't always:
“Is this memory completely accurate?”
Sometimes it's:
“What is this person experiencing while telling me?”
Are they animated?
Laughing?
Proud?
Interested?
Engaged?
Do they suddenly have more to say?
If so, perhaps the conversation is already accomplishing something valuable.
There is also an important caution here. Not every old memory is pleasant. Reminiscence can uncover grief, trauma, regret and loss. If a subject produces obvious distress, there's no reason to keep digging simply because remembering is supposed to be therapeutic.
The person's emotional response should lead the conversation.
The Memory Doesn't Have to Last for the Experience to Matter
This may be one of the hardest ideas about dementia for families to absorb.
An experience doesn't become meaningless simply because someone won't remember it tomorrow.
If someone laughs for twenty minutes and later forgets what was funny, they still laughed for twenty minutes.
If an old song makes someone feel safe, that safety existed.
If telling a story makes someone feel interesting, knowledgeable, funny or useful, that feeling existed too.
And if talking about an earlier life allows someone to spend half an hour inhabiting the parts of themselves that remain accessible instead of repeatedly confronting the things they've lost, perhaps that has value all by itself.
We spend enormous amounts of time thinking about what people with dementia can no longer remember.
Maybe occasionally we should ask them what they still know.
And then sit down and listen.
