For 30 years her husband, Richard Cohen, a respected news producer and writer, has lived with multiple sclerosis. Now he has written an inspiring account of that battle in his new book, Blindsided.

"I've pretty much made fun of him all the time," Vieira says. "Because that's the kind of relationship we have. We poke fun at each other."

The book is a brutally honest and raw portrait of their family's refusal to give into the ravages of chronic illness. Above all, it is a love story about surviving, and rising above fear and anger.

MS has taken its toll on Cohen. He is legally blind and the disease has also attacked his vocal cords, arms and legs.

Mysterious and unpredictable, MS is a neurological disease that affects an estimated 400,000 Americans, rarely fatal, but it wreaks havoc on the body's central nervous system and can cause blindness, loss of balance, slurred speech, tremors, and paralysis. There is no cure and patients never know where it will strike next.

Cohen's first glimpse of the storm ahead came when he was 19 years old. His father, a doctor, revealed to him the family secret that he and Cohen's grandmother had MS. A few years later, Cohen was working as a news researcher when suddenly he became disoriented, spilling coffee, slipping on the street, his leg going numb.

When he was 25, he learned he had MS.

"There's an expression 'diagnose and adios,' and 'see ya, because really there were no treatments of any kind," says Cohen.

For years he worked as a producer at CBS keeping his diagnosis a secret. "I lied to get the job," he says. "I faked my way through the company physical … I was scared to death because by now I was somewhat blind in both eyes. "

He eventually told his bosses and then pressed on covering wars and politics.
