NEW YORK (AP) _ Montel Williams has been diagnosed with multiple sclerosis but told reporters Monday he won't quit his talk show.

``This disease is not going to stop me,'' said Williams, who was accompanied by his wife, Grace, at a news conference.

``We don't know how long I've had it for, but I've been misdiagnosed for 10 years,'' he said.

Williams, 43, is considering several recently approved drugs and is starting a fund drive to find a cure for the crippling disease.

MS is a degenerative disorder of the nervous system. Victims typically typically lose some problem-solving capacity and short-term memory. Most end up in wheelchairs or need help walking.
