INTEREST in encephalitis associated with measles has increased considerably within the last two decades. At the time of an earlier report by Neal and one of us (E. A.)1 in 1927, this condition was just beginning to be generally recognized as a distinct clinical entity. In 1928, Ford,2 in an excellent paper, collected 113 cases from the literature and added 12 of his own. Subsequent detailed clinical records were given by Peterman and Fox3 in 1939, by Hamilton and Hanna4 in 1941 and by Litvak and associates5 in 1943. Reports dealing with the pathologic aspects of this condition by Wohlwill6 appeared in 1928, by Zimmerman and Yannet7 in 1930, by Ferraro and Scheffer8 in 1931, by Finley9 in 1937, by Malamud in 193710 and in 193911 and by Ziskind and Schattenburg12 in 1939.
