## Abstract

This document amends the Department of Veterans Affairs (VA) adjudication regulations concerning presumptive service connection for certain diseases based upon the most recent National Academy of Sciences (NAS) Institute of Medicine committee report, Veterans and Agent Orange: Update 2008 (Update 2008). This amendment is necessary to implement the decision of the Secretary of Veterans Affairs that there is a positive association between exposure to certain herbicides and the subsequent development of hairy cell leukemia and other chronic B- cell leukemias, Parkinson's disease, and ischemic heart disease. The effect of this amendment is to establish presumptive service connection for these diseases based on herbicide exposure.
