EAST MEADOW - Thousands of people turned out today to raise funds for multiple sclerosis research, the often-debilitating central nervous system disease that affects an estimated 42,000 people across Long Island.

About 3,000 people in all came out for the National Multiple Sclerosis Society's Walk MS in Eishenhower Park to fund research and raise awareness. The Long Island chapter of the society hoped to raise $1 million.

Organizers say the National Multiple Sclerosis Society is the top-funding organization for research in the world, and it works with other agencies to raise funds.

According to the Mayo Clinic, warning signs of the disease include numbness or weakness of the limbs, partial or complete vision loss, slurred speech, fatigue and dizziness.
