Author’s Tranquility Press Announces: "When the Mind Forgets, the Heart Remembers"
One Husband’s Tender Fight Against Alzheimer’s—and the Love That Never Let Go

In the hushed hours of early morning, when the rest of the world slept, Fred Buse often sat beside his wife Dot, whispering answers to the same questions she'd asked the night before.

She didn’t remember.

But he did.

And he never stopped answering.

In his moving memoir, A Caregiver’s Tips: My Wife Had Alzheimer’s Disease, now available on Amazon and released by Author’s Tranquility Press, Fred shares not just the medical reality of Alzheimer’s—but the emotional landscape of living each day with someone who is slowly drifting out to sea while you stand on the shore, waving, calling their name.

This is his story—and Dot’s.

The Vow That Outlived Memory

Fred made a promise on his wedding day: in sickness and in health, until death do us part. And he kept it—not out of obligation, but out of devotion so deep it did not flinch, even when Dot no longer knew his name.

Fred became her full-time caregiver. He cooked her meals. Brushed her hair. Watched her speak to people no one else could see. Held her when she cried for her mother who’d been gone for decades.

He gave her a life of dignity. A life of love.

And now, through this book, he gives the same to others.

134 Lessons from a Heart That Broke and Kept Loving Anyway

This is not a “how-to” guide from a doctor’s office. This is a bedside chronicle from someone who walked the entire journey.

Inside you’ll find:

  • Real-world caregiving advice Fred learned by trial, error, and heartbreak

  • Tips on managing wandering, confusion, medication side effects, and legal hurdles

  • How to prepare emotionally and spiritually for “the long goodbye”

  • Moments of joy—yes, even joy—that Alzheimer’s couldn’t steal

  • The strength to let go, when the time finally comes

These 134 insights are not just helpful—they are sacred. Earned through love. Paid for in tears.

For the Ones Who Hold Everything Together

This book is for the quiet warriors. The caregivers who rise every day and choose love, again and again, even when their hearts are breaking.

It’s for those who wonder if anyone sees them.

For those who feel exhausted but keep going.

For those who have whispered, I can’t do this another day—and then did it anyway.

Available Now on Amazon

If you’ve ever loved someone through Alzheimer’s, this book will feel like home.

It will cry with you.

It will breathe with you.

It will remind you that you are not invisible—and you are not alone.

Get your copy today. This is not just a book. It’s a love story that defies memory. Let it meet you where you are—and carry you forward. Visit his official website: https://fredericbuse.com
