My search for "anosmic" and "ageusic" took me to the National Institute on Deafness and other Communication Diseases. Finally, I found the root of "anaptic" ("aphia") on this page, which happens to have a host of other words you might find useful (some of which are already in this list): Terms for Cognitive, Behavioral and Neurologic Disorders.
