On discovering she had multiple sclerosis, Patricia Lay-Dorsey decided to photograph how her body and her life have altered, and how she feels about it.
The Detroit-based artist was diagnosed with chronic progressive MS in 1988 when she was 45. At the time she was running marathons for fun and taking 200-mile bicycle tours.
Lay-Dorsey started taking self-portraits six years ago. She says it has made her think more positively about her new body and hopes her work will change attitudes.
