“I don’t know what happened, but since we’ve been doing these sessions with old photos, Mr. D. is calmer. He participates in meals. He looks at us when we talk to him.” This type of feedback is regularly shared by caregivers in nursing homes after implementing reminiscence activities. It’s not magic — it’s applied neuropsychology with kindness.
The effects of therapeutic reminiscence in people with Alzheimer's disease and related disorders are documented by decades of clinical research. This article presents them concretely — so that caregivers understand what is happening and can discuss it clearly with their teams and families.
1. What research says
Therapeutic reminiscence is included in international recommendations for non-pharmacological management of Alzheimer's disease — notably those from the WHO, the French National Authority for Health (HAS), and the National Institute for Health and Care Excellence (NICE) in the UK. These recommendations are based on a solid body of controlled studies and meta-analyses.
A meta-analysis published in the British Journal of Clinical Psychology covering 128 studies and over 10,000 participants concludes that reminiscence has significant positive effects on well-being, depression, quality of life, and problematic behaviors in elderly people in institutions. These effects are observed in both individual and group sessions.
2. Effect on depression and anxiety
Depression affects between 30 and 50% of residents in nursing homes — often underdiagnosed and undertreated. Therapeutic reminiscence is one of the best-documented non-pharmacological approaches to reduce depressive symptoms in this population.
Its mechanism of action is multiple. Access to positive memories generates positive emotions that counterbalance depressive affect. Recognizing one’s own history reinforces the feeling of having led a meaningful life. And the bond with the caregiver created during the sessions meets the need for social connection — often deeply deficient in institutions.
What studies show. Reminiscence programs of 6 to 12 sessions produce an average reduction of 25 to 35% in depression scores on validated scales (GDS, Cornell Scale). These effects often persist for several weeks after the end of the program — and are reinforced when the approach is integrated into daily care rather than confined to formal sessions alone.
3. Reduction of agitation and BPSD
Behavioral and psychological symptoms of dementia (BPSD) — agitation, wandering, shouting, aggression — represent one of the heaviest challenges for nursing home teams. They are also one of the main causes of psychotropic prescriptions for residents with dementia — a prescription that has significant side effects and whose reduction is a public health objective.
Therapeutic reminiscence, by reducing the anxiety underlying agitation behaviors and providing a space for connection and meaning, can help reduce certain BPSD — particularly agitation related to anxiety and identity disorientation.
🎵 Biographical music
Songs from the resident's youth are particularly effective in reducing agitation — sometimes in just a few minutes. They activate emotional and procedural memory, preserved late in the disease.
📸 Childhood photos
Looking at and commenting on photos from one’s past can interrupt an episode of agitation by giving the person an identity anchor and a meaningful occupation.
👐 Sensory objects
Holding a familiar object — a tool from their former job, a fabric from home — activates procedural memory and often calms motor agitation.
🌹 Biographical scents
Scents related to personal history (bread, coffee, lavender, wood) are processed by the amygdala — an emotional structure preserved for a long time — and can trigger very powerful memories and positive emotions.
4. Improvement of communication
One of the most visible and immediately gratifying effects for caregivers is the improvement of communication during and after reminiscence activities. Residents who are usually mute or not very communicative can become verbally active, precise, animated — sometimes surprisingly so for caregivers who see them every day.
“Mrs. L. never said much to us. One day, I placed an old photo of Marseille on the table — she came from the Old Port. She started talking for twenty minutes. She described the fish market, the smell, the colors, the cries of the vendors. She was laughing. The next day, she had returned to her usual silence — but we had seen her differently. And she had seen us differently.”
This improvement in communication has cascading effects — on the quality of care (the team better understands the resident's needs), on the caregiver-resident relationship (the person is seen as a conversational partner), and on the feeling of being recognized and heard that the resident experiences.
5. Strengthening identity and self-esteem
Alzheimer's disease gradually erodes what allows a person to recognize themselves in the present — recent memory, temporal markers, daily skills. Reminiscence offers a powerful counterweight: it provides access to a part of oneself that remains intact — lived history, accomplishments, connections, values.
A resident who recounts how they built their house with their own hands, raised their children, faced challenges — during this time, they regain a pride and dignity that the disease cannot take away from them. This experience of oneself as a person of value and history is fundamental to psychological well-being.
6. Quality of caregiver-resident relationship
The benefits of reminiscence do not only concern residents. They also transform caregivers — and thereby, the quality of care provided. A caregiver who knows a resident's story — who knows they were a teacher, that they lost a child, that they sang in a choir — develops an empathy and patience that cannot arise from clinical knowledge alone.
Teams that regularly practice reminiscence report a transformation in their relationship to work — less burnout in the face of difficult behaviors, more meaning in daily gestures, better resistance to the emotional distance that the institution can induce. Caring for someone whose story you know is different from caring for a room number.
Encourage each caregiver to collect two or three key biographical elements from each resident they regularly care for — and to note them in the care file. Not the medical file — the life file. This information becomes entry points for daily reminiscence.
7. Benefits for families
Therapeutic reminiscence also has documented effects on the families of residents — particularly on close caregivers who have long accompanied a parent through illness.
Participating in reminiscence sessions with their loved one allows them to regain a form of relationship that is not defined by the disease — to see the person they once knew, and not just the patient they are accompanying. It reduces the feeling of anticipatory grief, the feeling of helplessness, and sometimes the guilt associated with institutionalization. And it strengthens their sense of being useful — they bring the photos, the objects, the stories that no one else can bring.
8. According to the stages of the disease
✦ Adapting reminiscence to the stages of the disease
- Mild stage — the person can participate in a structured life review, build a coherent narrative, express nuanced emotions. Reminiscence groups work well. Verbal communication is rich.
- Moderate stage — individual sessions are more suitable. Sensory supports (photos, music, objects) take more space than verbal narrative. Duration is reduced (20 to 30 minutes maximum). Emotions are still very accessible.
- Severe stage — sensory reminiscence (music, scents, textures) remains possible and beneficial. Non-verbal communication — smiling, eye contact, hand-holding — is at the forefront. The benefits are primarily emotional and relational.
9. The limits to know
Therapeutic reminiscence is not an approach without risks or limits. Knowing it honestly allows for discerning practice.
Some memories can be painful — unresolved grief, trauma, regrets — and their emergence requires the caregiver's ability to welcome them without fleeing or amplifying them. Reminiscence is not indicated for individuals with obsessive reminiscence (compulsive return to negative memories) without specific psychological support.
Furthermore, the benefits are not permanent — they require regular practice to be maintained over time. An isolated session provides a moment of well-being; an integrated program within care produces lasting effects.
10. Integrating reminiscence into the care plan
For the benefits of reminiscence to be lasting and shared by the entire team, it must be integrated into the resident's personalized care plan — not left solely to the initiative of a few motivated caregivers. This involves gathering each resident's life story upon entry, sharing this information within the team, identifying suitable biographical supports, and training all staff on the basic principles and tools.
