Kenneth Mitchell’s Cause of Death

“With heavy hearts we announce the passing of Kenneth Alexander Mitchell, beloved father, husband, brother, uncle, son and dear friend,” the family’s message read.

Mitchell was diagnosed with ALS in 2018 and died due to complications related to this disease.

He and his family shared periodic updates about his health in recent years. In August, Mitchell marked the fifth anniversary of his diagnosis in a post on Instagram.

ALS (amyotrophic lateral sclerosis) is a neurological disorder that causes paralysis and death and which only gets worse for the patient over time.

There is no cure at the moment.

How Long Was Kenneth Sick?

Last August, Mitchell marked the fifth anniversary of his diagnosis via a post on Instagram, writing at the time:

“My brother humorously mentioned that they don’t really have a happy ALS Anniversary card in the shop. However, I want to celebrate today; the gift of life. I’m so thankful to have this day in front of me.

“It’s been a long 5 years. So much lost, so much gained. Incredibly hard times, mixed with so many more blessings.

“At the heart of it all are friends and family, caregivers and doctors coming to the aid of my family over and over and over again. Giving a plethora of support and love and care and encouragement.

“There is so much beauty in that. This disease is absolutely horrific…yet despite all the suffering, there is so much to be grateful for.”

In his family’s moving statement, they expressed their admiration for the strength their loved showed as he lived with ALS.

“Regardless of his later disabilities, Ken discovered a higher calling to be more fully himself for his kids,” they wrote.

“For five and a half years Ken faced a series of awful challenges from ALS.
