Thanks to Google's generative models, such as Nano Banana, people with dementia can relive memories and experience significant emotional relief. Manel, a 68-year-old from Barcelona diagnosed with Alzheimer's in 2024, participated in a unique experience: he described his first love to a team of designers, a youthful memory involving a rectangular planter. Minutes later, he held an image of that moment, created by artificial intelligence. Although the planter turned out to be round, the scene matched what Manel had kept in his memory for decades. This image was generated by Domestic Data Streamers, a design studio in Barcelona that drives the Synthetic Memories project. Funded by Google and in collaboration with the Fundació Catalunya-La Pedrera, the project uses Gemini's generative AI (Nano Banana) to visually recreate memories that were never photographed, helping people with dementia reconnect with their past and identity. The project's value lies in its emotional impact on participants. Manel confessed he did not expect such precision and realism, while his wife Rosa was moved to see thoughts transformed into tangible images. The process resembles classic reminiscence therapy, scientifically validated and used in clinical settings to help patients connect with meaningful memories, even if they do not recover lost memory. Airí Dordas, a designer at the studio, explains that the goal is to create images of memories that still live in the minds of people with dementia, reinforcing their sense of identity and well-being. "When you help someone connect with their recognized reality, you contribute to their happiness," she states. Manel describes the experience as an emotional journey: "I felt melancholy, but also satisfaction. It's my youth, and it's a very positive act of memory." A key decision of the project is to keep the images with a blurry and evocative touch, avoiding confusion with objective evidence of the past. "Memory is subjective and changes over time," Dordas points out. Therefore, the team prefers to create "memory vectors," images that evoke emotions rather than document facts. In Manel's case, the image was clearer than usual thanks to Google's tools, adapting to his needs. The process is artisanal: the participant describes the memory, the team generates images, and adjusts them according to feedback until achieving the most faithful version possible. The Nano Banana technology allows for specific details to be modified without altering the rest of the image, facilitating personalization. In 2024, Domestic Data Streamers organized the Synthetic Memories Citizen Office exhibition at the Disseny Hub in Barcelona, where over 250 people shared memories that transformed into images in real-time. Among the participants was Pepita Bernat, 105 years old, who recounted the arrival of the first train to her village, and Carles Vallejo, who evoked clandestine union meetings without photographic records. Following this experience, the project aims to train psychologists and therapists to apply the methodology in nursing homes and day centers, expanding its reach. Collaboration with the Fundació Catalunya-La Pedrera allows healthcare staff, familiar with the patients, to use the tool directly. Manel, satisfied with the experience, states he would participate again and emphasizes the importance of public access. He cherishes the image of his first love, which allowed him to relive emotions and memories from a special time.
