For 25 years, Lyn Culbert lived with the knowledge that her son's life would be far too short.
Dave Lewis was diagnosed at 14 with Friedreich's ataxia, a rare inherited neuromuscular disease that gradually eroded his balance, coordination and speech and damaged his heart. As an adult, he managed to live on his own, but in his final few years he needed an increasing amount of support.
Culbert was always there to provide it.
"He trained me how to help him," said Culbert, 71, who lives in St. Louis Park and has two other adult children.
A retired project manager, she was available to take Lewis to his many medical appointments. She communicated on his behalf when service providers either could not understand Lewis' faint and slurred speech or ignored him altogether. She got up in the middle of the night and drove the four miles to his house whenever he needed her.
Then, at age 39, Dave Lewis died.
"At the end of the year when he died, I was just beside myself. I thought, how can I go into a new year without him?" Culbert said, tearing up at the memory.
But her son still needed her help.
