'9-1-1: Nashville' Actress Isabelle Tate's Cause of Death Revealed

9-1-1: Nashville star Isabelle Tate’s cause of death has been revealed.

Tate died from a rare neurological disorder, the actress’ agency revealed on Thursday, October 23.

“Isabelle ‘Izzy’ Tate had a rare form of Charcot-Marie-Tooth disease,” the McCray Agency shared via its Instagram Story. “She passed away peacefully on the 19th of October. The family requests privacy as they deal with this sudden and shocking loss.”

Tate’s agency directed followers to learn more about the hereditary disease through the Charcot-Marie-Tooth Association.

Charcot-Marie-Tooth disease is “a group of inherited conditions that cause nerve damage,” according to Mayo Clinic. “Inherited conditions pass down through families. This damage mainly is in the nerves of the arms and legs, called the peripheral nerves. Charcot-Marie-Tooth disease also is called hereditary motor and sensory neuropathy.”

Charcot-Marie-Tooth disease causes smaller, weaker muscles and can lead to trouble walking, as well as loss of feeling in the legs and feet. Other symptoms include high arches, curled toes, tripping often and clumsy walking.

Tate died at age 23 on October 19, her agency confirmed on Wednesday, October 22.

“We are deeply saddened and completely heartbroken to share that Isabelle Tate passed away on October 19th. She was 23,” a Facebook post read. “I’ve known Izzy since she was a teenager and she recently returned to acting. She booked the first series she auditioned for, 9-1-1 Nashville. She had a wonderful time.”

Tate’s reps also shared information from her obituary.

“Isabelle loved volunteering her time to all things, particularly animals — her idea of a fun outing was visiting an animal shelter and doling out lots of love,” the website read. “Isabelle was full of fire, a fighter, never once making excuses for the fact that she might have a disability relative to others.”

The obituary continued, “She was also quite musically inclined, often spending hours writing and recording songs with friends and even publishing a few. What she loved the most, though, was spending time with family and friends, always the life of the party. Her sister was her best friend and her mom was her shining beacon of light.”

Tate appeared in the 9-1-1: Nashville premiere earlier this month, portraying a guest at a bachelorette party who got a dance from stripper-turned-firefighter Blue (Hunter McVey).

While Tate did not often discuss her health battle via social media, she opened up about her neuromuscular disease in a December 2022 Instagram post.

“When I was 13, I got diagnosed with a progressive neuromuscular disease that weakens my leg muscles over time,” she wrote. “When I was first diagnosed, I couldn’t fully understand what it was or grasp what it could be. Over the years, I was going on with my life and would notice little things get more difficult for me.”

Tate revealed that her illness had “really progressed” by December 2022.

“I’ve come to terms that if I want to live my life to the fullest, I need to use a wheelchair at times,” she continued. “This has been a difficult journey for me because having to accept help and surrender to the progression of this condition has been extremely hard.”

Tate added, “I can’t change it, so I’m choosing to embrace it and not let it define me. This has really changed my perspective on life, and if I’ve learned anything from this, it’s to appreciate the little things that are easily taken for granted.”
