To quote Donald Rumsfeld, “there are things we know we know…. we know there are some things we do not know... But there are also unknown unknowns—the ones we don't know we don't know…it is the latter category that tends to be the difficult ones.”
In neurology, the agnosias are not that dissimilar from Rumsfeld’s 'unknown unknowns.' In this week’s program, we discuss the nosology and nomenclature for the agnosias, the localization, and the importance of recognizing one.
Produced by James E Siegler. Music courtesy of Dr. Turtle, Grossman, Ewell and Grainger, Marco Trovatelli, and Purple Planet Music. The opening theme was composed by Jimothy Dalton.
