In January of 1999, I received the following letter, from a woman I will call Anna H.:Dear Dr. Sacks,My (very unusual) problem, in one sentence, and in non-medical terms, is:I can’t read. I can’t read music, or anything else.In the ophthalmologist’s office, I can read the individual letters on the eye chart down to the last line. But I cannot read words, and music gives me the same problem. I have struggled with this for years, have been to the best doctors, and no one has been able to help.I would be ever so happy and grateful if you could find the time to see me.Sincerely yours,Anna H.
