BOSTON -- Former Massachusetts first lady Ann Romney is joining forces with Montel Williams and Jack Osbourne in a social media campaign to raise awareness of neurological disorders.

The three, who are all living with multiple sclerosis, are promoting the #50MillionFaces campaign, which encourages people with MS, Alzheimer's disease, Lou Gehrig's disease, Parkinson's disease and brain tumors to share their personal stories on Twitter and Facebook.

''The point is to let people have the opportunity to tell their stories and share them so that they don't feel so alone,'' Romney said in an interview earlier this week. ''They're battling these illnesses that are so overwhelming and they become depressed and sometimes suicidal.''

The ''50 million'' refers to the number of people believed to be affected by the illnesses worldwide.

The campaign, announced earlier this week, also encourages people to donate to the Ann Romney Center for Neurologic Diseases that the Romneys and their political allies help launch at Brigham and Women's Hospital in October.
