What happens when a loved one is trying to age at home, their memory is changing, and their medications suddenly start causing more harm than help?

In this episode of DNA Today, we’re talking about aging in place, memory care, and an often-overlooked piece of the puzzle, how someone’s genetics can affect the way they respond to medications later in life.

Our guest is Michele Magner, a Certified Dementia Practitioner, caregiver advocate, and educator who works closely with families navigating dementia, chronic illness, and the emotional realities of caregiving. With deep experience in senior living, gerontology, and family coaching, Michele helps people prepare not just for what’s happening now, but for what comes next.

We’ll explore how pharmacogenomics fits into home-based elder care, why medication reactions are so common in older adults, and how caregivers can better advocate for safer, more personalized care.

On This Episode We Discuss:

Aging in Place & Memory Care

What families are most concerned about when trying to keep a loved one at home
How memory-related illnesses change caregiving compared to physical limitations alone
Common misconceptions about the progression of cognitive decline
What “successful aging in place” realistically looks like

Medication Challenges in Older Adults

Why polypharmacy is so common—and so risky—in later life
How medications that once worked well can become problematic over time
Real-world examples of unexpected medication reactions in individuals with memory changes
Why older adults are especially vulnerable to side effects, particularly with cognitive impairment

Pharmacogenomics, Explained for Caregivers

What pharmacogenomics (PGX) is and how to explain it to families in practical terms
Why genetic-informed prescribing can become relevant later in life, even if medications were previously tolerated
How PGX may help prevent medication-related crises before they happen

PGX in Home-Based Memory Care

How pharmacogenomics could reshape medication decisions for dementia care
Medication categories that often raise red flags in older adults
How genetic insights may help protect individuals who can’t clearly report side effects

Advocacy, Access & System Gaps

Barriers families face when trying to access PGX-informed care
How caregivers can request medication reviews without feeling confrontational
Where healthcare systems often fall short of the realities families manage at home

Looking Ahead

What it would mean to routinely integrate pharmacogenomics into elder care
Michele’s key message for caregivers navigating medications, memory care, and aging in place
