AI in Dementia & PSP: Diagnosis, Care Support & Memory Preservation

Introduction

Neurodegenerative diseases such as Progressive Supranuclear Palsy (PSP), Alzheimer’s disease and other forms of dementia present profound challenges, not only for the person affected, but for their families, caregivers, and loved ones. The gradual decline in memory, identity, cognition and physical ability often leads to loss of independence, dignity, and the meaningful routines that make life worth living.

But emerging advances in artificial intelligence (AI) offer real hope. Far from being simply clinical tools, AI systems can become companions, custodians of identity, and bridges between past and present. If introduced early, while capacity, memory, speech and personality remain intact, AI has the potential to support not only everyday care and safety, but also preserve the person’s history, identity and dignity.

Below is a comprehensive look at how AI, thoughtfully implemented, could transform the care journey for people with neurodegenerative disease and offer lasting value for their families.

Early Detection & Diagnosis: Seeing What the Eye Cannot

One of the most promising applications of AI lies in improving early detection of neurodegenerative conditions. Detecting disease earlier gives crucial time to plan care, record memories, and mobilize support, before major decline sets in.

• A 2025 study using data from nearly 20,000 participants in the UK Biobank found that an AI algorithm, combining brain scans and data from wearable activity trackers, could spot early signs of dementia or Parkinson-type disease years before clinical diagnosis.
• Broader reviews find that AI-based “digital biomarkers”, using neuroimaging, speech patterns, behaviour, and activity data, are increasingly capable of detecting early cognitive decline more accurately and sooner than traditional clinical tests.
• Early detection allows people and their families to take proactive steps: adapt living environments, establish care routines, and, crucially, begin building a digital record of life ASAP.

This ability to “see what the eye cannot” means that by the time memory or motor symptoms become obvious, AI may already have flagged subtle changes, forever changing what “early diagnosis” can look like.

Personalized & Adaptive Support, “Learning Who They Are”

Once the possibility or diagnosis of neurodegeneration is identified, AI can provide a range of personalised supports, helping people maintain independence, safety, and quality of life for as long as possible.

• Home-based AI systems, combining sensors, wearables, and automation, can assist with everyday tasks, monitor safety, and reduce risk (e.g. falls, missed medication, wandering).
• Cognitive-assistive technologies, including AI-driven cognitive training tools, can help in maintaining mental function, stimulating memory, and possibly slowing decline.
• “Social” or companion robots, or AI-driven conversational agents, are being developed to offer emotional support, memory prompts, and gentle interaction. One recent project described a robot-based solution that engages patients with Alzheimer’s in conversations about their life, presents familiar images/videos to trigger memory, and adapts dialogue to individual backgrounds.
• Because AI learns over time, support can adapt as the person’s abilities change: from prompting complex tasks to simple reminders, from spoken suggestions to automatic or tactile cues.

By learning who a person is, their habits, preferences, history, AI can deliver support that feels personal, humane and respectful, not generic.

Preserving Identity, Memories & Personal History, A Legacy for Loved Ones

Beyond practical care, one of the most powerful uses of AI lies in capturing and preserving the person’s identity, a living memory bank for family and loved ones.

• Early in the diagnosis journey, when the person still has memory, speech and self-awareness, AI tools (or simple digital platforms) can be used to record voice, conversations, personal reflections, photos, favourite music, stories from the past, daily thoughts, habits and preferences.
• Over time, this builds a digital autobiography: a rich, searchable, and emotional archive of who the person was, their history, humour, values, and life story.
• As the disease progresses and memory fades, this archive becomes precious: family members, grandchildren, future generations can revisit voices, watch videos, hear laughter, read stories, preserving dignity and connection when the person themselves might no longer recognise loved ones.

This is not medical, it is profoundly human. AI becomes a custodian of identity and memory, ensuring that a life is never “lost,” even if memory declines.

Simplifying Everyday Tech, Making the Home a Comfort Rather Than a Challenge

As neurodegeneration advances, everyday technology can become a source of frustration and confusion. Complex remotes, TVs, streaming menus, video call apps, these often pose insurmountable barriers to someone with cognitive decline.

AI has potential to transform this:

• Imagine a tablet or smart device equipped with a personalised AI interface that learns what the person likes (favourite shows, films, music, photo albums, video-calls) and presents a simple, easy-to-tap dashboard, a “just-tap to play/watch” home screen. No menus, no confusing navigation: just what they love.
• As abilities change, the interface adapts, auto-play, voice commands, simplified prompts. AI can turn complexity back into comfort and familiarity.
• Behind the scenes, families or carers could update preferences, remind people of events, or upload new photos, ensuring the system evolves with the person’s routines and tastes.

This approach helps preserve autonomy, dignity, and simple pleasure, things often lost too early in dementia care.

Guiding Families & Carers, AI as a Quiet, Informing Companion

Caring for someone with PSP or dementia is seldom straightforward. It’s emotionally draining, unpredictable, and often isolating. AI can play a role beyond direct patient support, by helping families and carers navigate the journey:

• AI systems can monitor patterns (sleep, activity, mood, behaviour), detect early signs of increased risk (falls, agitation, confusion), and alert carers or professionals, enabling proactive care, not reactive crisis management.
• It can help interpret behavioural changes (e.g. “sundowning,” mood swings, withdrawal), offer advice on communication or care strategies, or suggest environmental adjustments for safety and comfort.
• By lightening the load of routine tasks and reminders, medication, appointments, daily schedule, AI can lower stress and burnout for carers, giving them space, time, and mental energy to focus on connection, love and human care.

In short, AI doesn't replace human compassion. It supports, reinforces, and augments it.

Challenges, Risks & Ethical Considerations, What We Must Keep in Mind

AI’s promise is immense, but real-world implementation demands caution and respect. Key challenges include:

• Research and validation, Much of the research into AI for dementia care is still early stage. Promising laboratory results don’t always translate smoothly into real-world settings.
• Privacy, consent and autonomy, Recording memories, using sensors or cameras, monitoring behaviour, these raise ethical questions. As cognitive ability declines, consent becomes complicated; dignity and autonomy must be protected.
• Digital inequality & accessibility, Not everyone has access to smart devices, reliable internet, or technical support. There is a risk of widening inequality, especially among older or economically disadvantaged populations.
• Over-reliance and “cognitive offloading”, There is a concern that excessive reliance on AI might reduce natural cognitive activity (memory, decision-making), possibly accelerating decline if not balanced with human interaction and engagement. Some researchers note that digital care must complement, not replace, human care.
• Emotional risks, For families, having a “digital copy” of a loved one can be comforting, but also painful; it may hinder acceptance or closure. The psychological impact needs careful thought.

Hence, deploying AI in dementia/PSP care must be done with empathy, respect, consent, and ongoing evaluation, not just as a tech solution, but as a deeply human service.

What This Could Look Like, A “Care Journey Scenario”

To bring it all together, here’s an example of how AI might support someone with neurodegenerative disease, from early diagnosis through later stages, while preserving identity, dignity, and connection.

1. Early Stage, Diagnosis or Early Detection
   • AI-powered neuroimaging and activity tracking identify early signs.
   • Prompt family to begin planning care and preserving memories.
   • Start building a “digital life archive”: photos, voice recordings, personal reflections, favourite songs, daily routines.
2. Home Setup & Adaptation, Smart & Gentle Assistive Environment
   • Install AI-based home support: reminders, fall detection, routine prompts.
   • Provide a personalised tablet interface for entertainment, music, TV, video calls, simplified for ease of use.
3. Cognitive & Emotional Support, Memory, Identity & Companionship
   • Use AI-driven cognitive exercises, memory-stimulating activities.
   • Optionally involve social-robot companions or conversational agents that interact gently and humanely, perhaps reminding of names, events, or favourite stories/photos.
4. Monitoring & Safety, Maintaining Independence Longer
   • Continuous background monitoring of behaviour, activity patterns, sleep, vital signs; alerts to carers for anomalies.
   • Automated routine adjustments: lighting, temperature, reminders, meal times, aligned to the person’s history and preferences.
5. Family Support & Guidance, Through Changing Needs
   • AI informs carers/family of potential changes (mobility, cognition, mood) earlier.
   • Offers advice on communication strategies, environment adaptations, care decisions.
   • Maintains the “digital legacy”, photos, stories, recordings, so loved ones can revisit and remember the person’s full life.
6. Long-Term, Legacy, Dignity and Memory
   • Even if the person loses ability to communicate, their voice, memories, preferences, and personality, preserved digitally, remain accessible.
   • Family, grandchildren, future generations can connect with the “real person” beyond the disease.
   • The person’s life is honoured, remembered, and kept alive through memory and digital presence.

Why This Matters, The Human and Social Value

• Neurodegenerative diseases are not just medical conditions, they erode identity, history, dignity. AI can help hold those things safe.
• Traditional care models (sit-down carers, nursing homes, periodic appointments) can’t always provide continuity, memory preservation, or the kind of personalised support an AI-enhanced environment can.
• As populations age and care needs rise globally, scalable but compassionate AI-based care-support systems could fill critical “care gaps.”
• For families already in the midst of caring (as you are), implementing AI early, while capacity remains, may be among the most meaningful, loving, and forward-looking decisions you make.

Conclusion, AI as a Companion to Compassion

AI’s greatest power in dementia or PSP care may not be in robotics or fancy devices, but in memory, dignity, stability, and human connection.

When used thoughtfully, early and respectfully, AI can become much more than medical support: it can be a custodian of a person’s story, a quiet companion in decline, a memory-keeper for loved ones, and a tool for dignity and legacy.

For someone navigating the slow decline of neurodegeneration, or their family, AI doesn’t replace what’s lost. It helps preserve what matters.
