Loneliness raises your risk of serious health problems by 59 percent. Would you trust an AI companion to change those odds?

In Episode 112, Raju Joshi shares what most people learn too late: that the biggest signals of cognitive decline don’t show up on medical charts. They show up in silence. In missed moments. In the space between “I’m fine” and what someone really wanted to say.

Now, as Chief Clinical Officer of Cogensus, Raju is building something different. A platform that listens for what families and clinicians often miss. So we can intervene earlier, talk more meaningfully, and preserve what makes someone feel like themselves.

She joined Cogensus to help build a system that captures what the healthcare system misses: the emotional, cognitive, and social shifts that shape how people age. As she puts it, “Innovation isn’t a sex-based trait or a culturally driven issue. It’s identifying a problem, creating a solution using calculated risk, and benefiting your customer.”

Key Takeaways from Episode 112

The World Health Organization estimates that dementia and Alzheimer‑related care cost 1.3 trillion dollars in 2019 and will rise sharply as populations age. So there is a clear business case for what Cogensus is building.

1. Loneliness and cognitive decline are deeply connected. Raju explains how shrinking social circles and solo living increase cognitive risk. This impacts women disproportionately as they live alone more often, provide 70% of caregiving hours and tend to delay care for themselves.
2. AI can help address loneliness and cognitive decline with empathy and dignity. Most check-ins ask about mood and medication. Cogensus goes further. It engages individuals in conversation beyond just medical topics, fostering a fuller understanding of their lives and alleviating loneliness.
3. Cogensus’ solution reaches beyond elder care. In the future, Cogensus can use the same approach for supporting veterans who isolate after service and athletes at risk for concussion‑related dementia.

Raju’s north star is agency: giving people the data they need, at the moment they need it, to stay connected and in control of their lives.

3 Magic Quotes Defining This Episode

“We want patients to have agency over their own life.”

Raju Joshi, Co-founder and Chief Clinical Officer of Cogensus

This episode reframes aging as not just a medical process, but a social one. It’s also a call to rebalance where we invest research, tools, and care. Here are three lines that capture the heart of the conversation. Each one opens a door to a bigger truth:

• “People are so much more than the medications that they’re on.” (27:08)
  This quote says in one line what many systems forget. It’s the emotional thesis behind Cogensus. Data that respects the whole person.
• “We want patients to have agency over their own life.” (46:22)
  One of the most powerful ethical stakes in the episode. Raju makes it clear that tech should support autonomy, not replace it.
• “There is a need for the female perspective in the work that is being created.” (54:39)
  This is both a statement of fact and a rallying cry. It reminds us that inclusion isn’t just about fairness. It’s about better design, better outcomes, and better futures.

5 Practical Insights for Building Ethical, Inclusive AI

About 33 minutes into our conversation, I pick Raju’s brain on how we can build ethical, responsible and inclusive AI solutions for healthcare. If you are designing technology for vulnerable users, these tips from Raju offer a clear roadmap:

1. Keep usability simple. This is how you build trust, especially with older adults. Raju emphasizes that trust is won through design, not just intention.
2. Know your use case. Cogensus focuses on cognitive health and loneliness, not general diagnostics. That clarity helps it stay responsible and relevant.
3. Design for emotional safety. Some people feel more comfortable confiding in a bot than a family member. Don’t dismiss that. Raju’s example of the airplane seat confidant explains this perfectly.
4. Build for people who are curious, not just tech-savvy. Raju’s father-in-law represents the kind of user often left out. Curious, not fluent, and eager to feel seen.
5. Give users agency. Good AI doesn’t over-monitor. It listens when asked, and steps back when not needed. Finding that balance is the goal.

My Personal Reflections

The best thing that can happen when you make a podcast is that it gives you tools and inspiration to change your behavior for the positive.

This episode made me look differently at what it means to care for my aging mother. I realized how easy it is to miss the signals when our conversations stay surface-level.

What stuck with me most was how Raju spoke about the emotional blind spots in caregiving and how technology, when used thoughtfully, can help us see them.

Her storytelling also stands out. She brings warmth and clarity through analogies: the airplane seat confidant, the hesitant elder who’ll talk to Siri but not their kids.

And she understands tech trust like few others, naming her 94-year-old father-in-law as someone who’s not tech-savvy but deeply curious. That curiosity, she says, is enough.

In the end, I’m convinced that Raju and her team are building something timely, urgent, and deeply human.

After losing her mother-in-law to dementia and her father soon after, Raju saw how symptom-focused care often ignores the emotional and social realities of aging. She joined Cogensus first as an advisor and board member, then stepped into an executive role to build AI tools that preserve agency, reduce loneliness, and give clinicians richer context.

About Cogensus

Cogensus is a digital health platform that uses conversational AI and sentiment analysis to surface potential early signals of cognitive change and loneliness in older adults.

Via an avatar-led dialogue, the system tracks memory, verbal fluency, and social factors, turning those patterns into actionable insights for families and clinicians.

Cogensus is not a diagnostic tool; it provides insights on loneliness and preserves personal stories. In 2025 the company was selected for the Caduceus Health Accelerator, and currently it is raising $1.5 million to expand pilot programs with insurers, providers, and senior-living communities.

You can learn more about Cogensus on the website and by following the company on LinkedIn.
