Olympic Gold Medalist Michael Klim

Australian swimmer Michael Klim can no longer walk unaided after a rare and incurable disease frequently left him unconscious.

I have a chronic problem with knee and lower back weakness and over the last few years I have noticed severe muscle atrophy in my legs loss of balance in my lower extremities and tingling in my knees. Thighs and difficulty getting out of bed.

According to the Brain Foundation, an Australian charity, the disease gradually causes weakness in the legs and arms. It is caused by an incorrect reaction of the immune system and the destruction of myelin.
