Dear Vanessa,
Why is it important to understand dementia—even if I don’t know anyone who has it?

Dear Mike,
It’s a question I’ve been asked many times—at community talks, during care planning meetings, even in casual conversations with friends outside the aging field. It usually comes from a place of genuine curiosity: “If dementia hasn’t touched my life, why should I learn about it?”
And I understand that perspective. But after years of working as a nurse, managing care for hundreds of older adults, and studying aging through the lens of gerontology, I’ve come to believe that understanding dementia is part of our shared social literacy. Not because everyone will face it personally, but because we’re all living in an aging society—and how we respond to cognitive change affects the quality of life for everyone.
Dementia is not a distant issue for “other people.” It’s present in our communities—in the neighbor who sometimes forgets the way home, the woman you see on the bus who asks the driver the same question twice, the coworker quietly navigating a parent’s recent diagnosis. You may not recognize it yet, but it’s there.
And knowing how dementia works—even at a basic level—allows us to engage with more confidence and humanity. When we understand that dementia affects short-term memory, orientation, and communication, we’re less likely to misread someone’s behavior as rudeness or confusion as incompetence. Instead, we respond with patience. We slow down. We connect.
This isn’t just professional insight—it’s personal, too. I’ve seen families transform simply because they learned what to expect. When a son begins to understand that his mother’s repetition is not intentional but part of a brain change, his frustration softens. When a caregiver learns to meet a client in the reality of their moment instead of correcting them, the home becomes calmer. These are quiet shifts that lead to big outcomes.
From a gerontology perspective, we also know that early recognition of dementia can lead to better care planning, increased safety, and improved long-term outcomes. It gives people time to make decisions while they still can—about their care, their finances, their wishes. It opens the door for meaningful conversations. And it empowers families to explore support options before reaching a crisis point.
But beyond planning and practicalities, there’s a bigger reason I believe this knowledge matters: understanding dementia helps reduce stigma.
For too long, people living with dementia have been silenced, underestimated, or dismissed. They’ve been kept on the margins of society instead of included in its design. But that’s changing. Around the world, cities are reimagining what it means to be dementia-friendly—creating public spaces that are easier to navigate, training shopkeepers and baristas to recognize signs, and encouraging intergenerational programs that build empathy and connection.
And it starts with awareness. Not fear. Not pity. Just the willingness to learn.
And one day, if it ever does touch your life—whether through a parent, a friend, or even your own aging journey—you won’t be caught off guard. You’ll be ready. Not just with knowledge, but with empathy.
That’s what a dementia-friendly society looks like. And we each have a role to play in building it.
Warmly, Vanessa
