In these instances, patients can read laboriously through letter-by-letter spelling, either aloud or silently. The more letters in the word, however, and the more time spent in naming the letters, the more likely are errors. The resulting paraplegias tend to be orthographically, rather than semantically, related to the target word. Patients with ALEXIA WITHOUT AGRAPHIA have little difficulty writing, but are virtually incapable of reading what they have written. Spared writing together with the preserved ability to comprehend orally spelled words, as well as letters and words traced on their palms, suggests preservation of stored orthographic information that cannot be accessed through the visual modality.
