2026 Alzheimer's Facts & Figures: What They Mean for Arizona Families

Each spring, the Alzheimer's Association releases its annual Facts & Figures report — the most-cited source of numbers on Alzheimer's in the country. The 2026 report is now out. It's long, it's careful, and it can feel like a wall of statistics when what you actually want is to know what it means for the person you love.

We'll try to translate. What follows is what stood out for Arizona families, and what we quietly took away from it as caregivers.

The Arizona picture

Arizona has approximately 150,000 residents age 65 and older living with Alzheimer's. That's more per capita than most states — partly because our climate and lifestyle attract older adults, and partly because we've done a better-than-average job of counting.

Zooming in on Maricopa County: roughly 100,000 of those Arizonans live here. And within that, North Scottsdale, Paradise Valley, Cave Creek, and the East Valley have some of the highest concentrations, simply because these communities skew older.

What this means for a family in Scottsdale: you are not alone. Whatever isolating experience you may be having right now — with a spouse who is changing, a mother who is forgetting, a father who is disappearing behind a new fog — thousands of your neighbors are somewhere on the same path. There are more resources here than in most places. There are also more good care options here than in most places, if you know where to look.

The national picture, and where it's headed

Nationally, the 2026 report puts the number of Americans age 65+ living with Alzheimer's at 7.2 million. The projection for 2050, without a treatment breakthrough, is nearly 13 million.

What those big numbers actually mean:

• Alzheimer's is the fifth-leading cause of death for Americans 65+ — and the only one in the top ten without an effective disease-modifying treatment for most people living with it.
• Two-thirds of Americans with Alzheimer's are women. Two-thirds of unpaid caregivers are also women. The disease weighs on women twice.
• Black and Hispanic Americans are two to one-and-a-half times more likely than white Americans to have Alzheimer's — with far less access to specialists.

The caregiver numbers no one wants to talk about

The report tracks the number that speaks most directly to the families we sit with: caregiver hours. In Arizona alone, roughly 275,000 unpaid family caregivers provide over 400 million hours of care per year. That works out to more than $8 billion in unpaid care at the market rate.

Two-thirds of those caregivers are women. Nearly one in three is also caring for a child — the "sandwich generation" that the report has been tracking for a decade. Rates of caregiver depression, sleep loss, and health decline are all measurably higher than the general population.

If you are the primary caregiver reading this: please hear us. The exhaustion you feel is not a personal failing. It is what the data has been saying for years about the load you are carrying. Getting real help — respite, a support group, a call to the 24/7 helpline — is not weakness. It's what makes the caregiving sustainable.

Three findings that changed our thinking in 2026

1. Risk reduction is real. The report devotes more space than ever to modifiable risk factors: cardiovascular health, hearing loss, sleep, social engagement, physical activity. See our companion piece on Brain Health Recommendations for 2026.
2. Diagnosis is finally improving. New blood-based biomarkers entered wider clinical use in 2025–2026, meaning families no longer have to wait months for a specialist and a PET scan to get an answer. This matters because early diagnosis changes planning windows dramatically.
3. Caregiver support measurably works. The report is unusually direct in 2026: caregivers connected to a support network report better health outcomes and are more likely to keep their loved one at home longer. Isolation is the enemy.

What we take from this as a small home

A few honest reflections:

• The demand for thoughtful memory care in Scottsdale is going to keep growing. Building the kind of home where a resident can move through the stages without moving buildings is part of the answer.
• Small ratios and consistent caregivers aren't a luxury for a family navigating dementia — they are the difference between confusion and safety.
• Supporting the family, not just the resident, is not extra. It's the job.

Where to reach out

The Alzheimer's Association Desert Southwest Chapter serves Arizona families. Their 24/7 helpline is 1-800-272-3900. Support groups, care consultations, and educational programs are free. We recommend them without reservation.

If you'd like to talk about what memory care looks like in a small nurse-led home in Scottsdale, please reach out. There's no urgency here — sometimes the most useful conversation is one that happens months before a decision.
