French actor Guillaume de Tonquédec sat down with Audrey Crespo-Mara on the television program “Sept à Huit” to bare a deeply private weight. At 59, the actor of “Fais pas ci, fais pas ça” detailed the devastating physical and cognitive decline of both parents.

The profound personal toll inspired a book, “Ta mère et moi,” published by Stock. He has since adapted the material into a solo stage production at the Théâtre de Paris.

A Multiple Sclerosis Diagnosis at 40

His mother was just 40 years old, and the mother of four children, when she received her multiple sclerosis diagnosis. The illness charted a slow, progressive course. It relentlessly attacked her motor functions yet somehow left her sense of humor and love of life entirely intact.

The news hit the actor in his twenties while he was rehearsing a play in Montpellier. He broke down in tears. His mother, remarkably stoic, met his grief with a sobering reality check: life is what it is, she told him, and things had changed permanently.

Decades ticked by. The disease tightened its grip, steadily restricting her mobility and shrinking her endurance and walking distance during severe flare-ups.

Caregiving Burnout and a Late Alzheimer’s Onset

Stepping into the breach, his father became the primary caregiver. He managed every daily task his wife could no longer handle, from fetching water to assisting with personal hygiene.

The relentless burden extracted a heavy physical price. Refusing outside help, the father ultimately suffered a heart attack driven by pure exhaustion.

Then came another blow. At age 85, he was diagnosed with Alzheimer’s disease. For the actor, this second diagnosis was a severe shock—a condition that systematically erased memory, vocabulary, and the shared family history, fueling his urgent need to document their story.

The Heavy Reality of Anticipatory Grief

Watching the simultaneous decline of both parents plunged the actor into what is medically and emotionally termed anticipatory grief, or “le deuil blanc.”

It creates a confusing role reversal. Children effectively become parents to their own mothers and fathers. This complex grief means mourning experiences that can no longer happen, like taking a train to Paris or visiting a museum together.

To honor their journey, he makes his feelings known. He regularly expresses his affection, noting that he frequently tells them he loves them.
