As the global population ages, dementia is rapidly becoming one of the most pressing public health challenges of our time. To address the growing needs of individuals and families affected by dementia, Lenovo™, in collaboration with Innovations in Dementia, unveiled a groundbreaking initiative at Lenovo Tech World: Alzheimer’s Intelligence, a photorealistic 3D avatar powered by custom AI. This proof-of-concept tool provides 24/7 conversational support, offering compassionate, personalized advice to those navigating a dementia diagnosis. It represents a bold step in leveraging technology to enhance human connection and support.

Globally, more than 55 million people live with dementia, and this number is expected to rise to 139 million by 2050, according to the World Health Organization (WHO). The economic toll is equally staggering, with annual costs exceeding $1 trillion, projected to double by mid-century. Dr. David Llewellyn, Professor of Clinical Epidemiology and Digital Health, emphasized the significance of Lenovo’s initiative:
“The AI advancements in Alzheimer’s Intelligence showcase the potential for technology to enrich human interaction. Tools like this provide invaluable support for individuals with dementia, both now and in the future.”

Doug Fisher, Lenovo’s Chief Security and AI Officer, highlighted the ethical responsibility of deploying such technology:
“With rapid advancements in AI, we have a responsibility to ensure it serves communities that are often overlooked. Alzheimer’s Intelligence embodies our commitment to Smarter AI for All—developing technology that empowers everyone, everywhere.”

A Look Inside Alzheimer’s Intelligence: Building Liv

At the heart of Alzheimer’s Intelligence is Liv, a photorealistic 3D avatar designed to engage users in natural, empathetic conversations. The creation process for Liv reflects a meticulous blend of technology and human experience.

1. Designing the Avatar:
   • Liv was developed using composite images of 10 individuals living with dementia.
   • Generative AI extrapolated thousands of facial expressions and angles from these images, creating a dataset that captures a wide range of emotions and naturalistic features.
   • The final avatar was enhanced using the facial expressions of a live performer, enabling Liv to convey nuanced emotions during conversations.
2. Training the AI:
   • A large language model (LLM) was trained on real-life data sourced from dementia patients. Contributions included entries from Innovations in Dementia’s Dementia Diaries project and panel interviews.
   • Liv’s responses are crafted to reflect the tone, language, and personality of someone who has lived with dementia, ensuring that advice feels authentic and relatable.
3. Conversation Mechanics:
   • Users interact with Liv via speech-to-text technology. Liv’s responses are generated using the LLM and voiced through a custom vocal synthesizer.
   • Sentiment analysis enhances interactions by adjusting Liv’s facial expressions to match the tone of her replies, creating a deeply empathetic user experience.
4. Real-Time Visuals:
   • Advanced 4K visual AI synchronizes Liv’s speech and facial movements in real time, ensuring a seamless and engaging interaction.

Bridging the Gap Between Knowledge and Compassion

Dementia is not only a medical condition but also a deeply personal journey that affects families emotionally, socially, and financially. The Alzheimer’s Intelligence initiative seeks to address the unique challenges faced by individuals with dementia and their caregivers.

Liv serves as a resource for:

• Understanding Daily Challenges: Offering tips on navigating memory loss, maintaining routines, and managing behavioral changes.
• Improving Communication: Helping individuals explain their condition to loved ones or find new ways to stay socially connected.
• Exploring New Hobbies: Encouraging activities that promote cognitive stimulation and emotional well-being.

Importantly, Liv is designed to complement, not replace, human interaction. As Steve Milton, Director of Innovations in Dementia, noted:
“When people are diagnosed with dementia, they often feel lost and overwhelmed. Liv doesn’t replace human connection but provides a compassionate, knowledgeable source of advice based on real experiences.”

The Technology Driving Alzheimer’s Intelligence

The success of Alzheimer’s Intelligence is rooted in Lenovo’s extensive technology portfolio, which spans hardware, software, and AI solutions. The project brought together cutting-edge devices and services, including:

• ThinkStation P7 servers and ThinkPad laptops for AI training and development.
• Legion monitors and ThinkVision accessories for enhanced visualization.
• A partnership with Kaleida, which provided AI professional services to ensure robust security and scalability.

These technologies were seamlessly integrated to create an avatar capable of natural, unscripted conversations, making Liv one of the most advanced AI tools for dementia support.

Dementia by the Numbers: Why This Matters

The urgency of addressing dementia is underscored by its global impact:

• In the United States alone, over 6 million people live with Alzheimer’s disease, the most common form of dementia. By 2050, this number could exceed 13 million.
• Dementia disproportionately affects women, who account for nearly two-thirds of all cases.
• Low- and middle-income countries bear the brunt of the epidemic, with nearly 60% of cases occurring in these regions.
• Caregivers often face significant burdens, with studies showing that 60% experience high levels of stress, and nearly 40% report symptoms of depression.

By providing accessible, round-the-clock support, tools like Liv have the potential to alleviate some of these burdens, offering caregivers practical advice and emotional reassurance.

Ethical Considerations and Privacy Safeguards

As with any AI-driven solution, ethical considerations are paramount. Lenovo and Innovations in Dementia implemented several safeguards to ensure Alzheimer’s Intelligence remains a trustworthy resource:

• Privacy First: User interactions are encrypted to protect sensitive data. No personal information is stored or shared.
• Medical Guardrails: Liv does not offer medical advice, focusing instead on lived experiences and practical tips.
• Inclusive Design: The avatar was tested with diverse user groups to ensure accessibility across cultures, languages, and levels of tech literacy.

These measures reflect a commitment to responsible AI development, ensuring that Liv serves as a reliable and compassionate companion.

Currently, Alzheimer’s Intelligence is being trialed in controlled environments, with plans to expand its availability. Early feedback has been overwhelmingly positive, with users praising the avatar’s ability to provide empathetic, relevant advice.

Potential future developments include:

• Scaling for Broader Use: Adapting the tool for other neurodegenerative conditions, such as Parkinson’s disease or multiple sclerosis.
• Cultural Customization: Expanding language support and cultural adaptations to serve global communities.
• Integration with Healthcare Systems: Partnering with healthcare providers to offer Liv as part of telehealth services, enhancing access in underserved areas.

Alzheimer’s Intelligence exemplifies how AI can be applied to address complex social and health challenges. By integrating advanced technology with the lived experiences of individuals, Lenovo and Innovations in Dementia have developed a tool designed to provide support for people with dementia while maintaining a focus on accessibility and respect for user needs.

Dementia care remains one of the most pressing global health challenges, and innovative solutions are essential. Alzheimer’s Intelligence stands out as a practical, empathetic tool for improving quality of life. Initiatives like this highlight the possibilities AI offers when thoughtfully and responsibly deployed. Liv represents a step forward in using technology to create practical resources for those navigating the challenges of dementia.
