I don't know enough about SDAM to know if it's the same thing as visual aphantasia, but they are presumably related. I am unable to visualize anyone's face (or, really, anything at all that isn't a black void), yet I can easily recognize the person (especially if I know them well) and I can describe them. What I can describe about them are whatever notes I've made about them to myself along the way (round face, black hair, mustache, broad chin, etc).
