Journalist Living With Alzheimer’s Narrates Expanded Audiobook of His Award-Winning Memoir ‘On Pluto’

​

Greg O’Brien reads his own story in an edition with a foreword recorded by ‘Still Alice’ author Lisa Genova, arriving just ahead of National Alzheimer’s Disease Awareness Month

BREWSTER, Mass. (Oct. 28, 2026) — Greg O’Brien, a veteran investigative journalist diagnosed with Alzheimer’s disease in 2010, has recorded an expanded audiobook edition of his award-winning memoir, “On Pluto: Inside the Mind of Alzheimer’s,” in his own voice. The audiobook, titled “On Pluto: Inside the Mind of Alzheimer’s — Reflections,” will be released Oct. 29 on Audible and Amazon, with distribution to Apple Books, Spotify, Chirp, OverDrive, hoopla and other platforms through Author’s Republic.

The edition opens with a foreword recorded by Lisa Genova, the neuroscientist and author of “Still Alice.” It adds a personal introduction by O’Brien’s daughter, Colleen O’Brien, and a closing summation from O’Brien himself. It also includes articles O’Brien wrote for Psychology Today.

“On Pluto” follows the progression of O’Brien’s disease from the point of view of an investigative reporter embedded inside it, an approach billed as a first for a book. The title uses the dwarf planet as a metaphor for the isolation and desolation of Alzheimer’s. The original book, published in 2014, won the Beverly Hills International Book Award for Medicine and the International Book Award for Health, and was a finalist for the Eric Hoffer International Book Award and the USA Best Book Awards.

Alzheimer’s took O’Brien’s maternal grandfather, his mother and a paternal uncle, and his father was diagnosed with dementia before his death. O’Brien was diagnosed at age 59, after two traumatic head injuries that doctors say unmasked a disease in the making. He was the family caregiver for both his mother and his father. O’Brien, 76, lives on Cape Cod.

“Having Greg narrate gives us the most credible and emotional impact, especially for those listening who are living with Alzheimer’s or any other form of dementia, knowing that they are not alone,” said Victor Warren, who produced and directed the audiobook.

Warren is an actor, director and audiobook narrator whose company, Glydascope, holds the audio rights. Sound engineer Thomas Milkey recorded the audiobook at his Cape Cod studio.

About 7.4 million Americans age 65 and older are living with Alzheimer’s dementia in 2026, according to the Alzheimer’s Association’s 2026 Alzheimer’s Disease Facts and Figures report. The World Health Organization estimates that more than 55 million people worldwide live with dementia. Alzheimer’s has no cure.

Genova, who also wrote the foreword to the printed book, praised its “extraordinary vulnerability, grace, humor, and profound insight.” Dr. Rudy Tanzi of Massachusetts General Hospital and Harvard Medical School called O’Brien “my hero.” New York Times best-selling author David Shenk wrote that “Alzheimer’s messed with the wrong man.”

The audiobook arrives just ahead of National Alzheimer’s Disease Awareness Month in November. O’Brien is available for interviews by video call.
