On December 4, 2014, Christelle Arrighi's life changed when her husband, Martin, was diagnosed with a brain glioma, a type of tumor that develops in the brain's glial cells. The couple had met in 2007, married in 2013, and welcomed their first child, Jeanne, in 2014. Martin's symptoms began after a weekend trip, when he experienced dizziness and a speech disorder. These symptoms led to an MRI that revealed a six-centimeter tumor in a part of the brain responsible for language and movement. Doctors believed the tumor might have been present since birth and was growing slowly. In February 2015, Martin underwent a ten-hour awake surgery to remove two-thirds of the tumor. However, he emerged from the operation unable to speak and with partial paralysis on one side of his body. Christelle became Martin's primary caregiver, helping with medical appointments, translating his speech, organizing daily life, and assisting with personal care. She described the role as natural, driven by her desire to support her husband, and rejected the term "caregiver," which she found too limiting. Martin's condition gradually improved, and the couple had two more children, Côme in 2018 and Arthur in 2021. However, in the autumn of 2024, the tumor was found to be a more aggressive form of glioblastoma, a type of brain cancer that is more difficult to treat. Despite treatments, Martin's condition worsened, and he lost his ability to speak, move, and live independently. Christelle took on the role of medical coordinator, managing schedules, blood tests, and chemotherapy while balancing her responsibilities as a wife and mother. She described the period as extremely challenging, noting the lack of preparation for such a role and the emotional toll it took. To maintain a sense of normalcy, Christelle continued working in retail and avoided the pitfall of waiting for Martin's death. Despite the strain, she did not regret her choices, stating that true love can endure hardship. Martin passed away on January 31, 2026, at the age of 41, leaving behind Christelle and their three children. In the following months, she experienced grief and anger but eventually found a renewed purpose. With other women who had lost loved ones to brain tumors, she founded the association Les Bonnets Gris in July 2026. The organization aims to raise awareness, support patients and caregivers, and fund research. Nearly one million euros have been raised to fund a five-year research project starting in November at the Pitié-Salpêtrière Hospital. Christelle now seeks to use her experience to provide hope and strength to others facing similar challenges.
