Jason DaSilva was 25 when he was diagnosed with multiple sclerosis. As a filmmaker, he eventually decided to try and make sense of the disease through his art form. So, he set out to capture what he calls the transformative experience of becoming disabled. DaSilva let the camera run as he dealt with his loss of vision, muscle control, and many other complications. Next week, we’re screening When I Walk as part of the Through the Lens documentary series. Wednesday, DaSilva joins us to talk about it.
