Glenntaj, citing this study and a previous study showing significant nerve damage to rats exposed to World Trade Center dust, as well as my own personnal exposure and medical history, on January 5th I petititioned the Center for Disease Control National Institute of Occupational Safety and Health, to have peripheral neuropathy added as a recognized condition resulting from exposure to World Trade Center Dust. This would apply for anyone thus exposed. They have 90 days to rule on the petition. In talking to the researchers, I was informed that in the case of severe peripheral neuropathy, there is 15 times the correlation between World Trade Center first responders and the general population not exposed. The petition is kind of a David vs. Goliath scenario, but we shall see. You have inspired me more than you know.
