People who suffer from agraphia can have many symptoms, and not all people with agraphia have all of the symptoms. Perhaps the most common symptom is the reluctance towards writing activities, which is due to the fact that writing is so much more difficult for those with agraphia. People who are agraphic often have problems with transposing, omitting, or adding letters to words, and their spelling suffers as a result. In addition, their letters may seem to fly off the lines or be placed haphazardly, and lowercase letters might be interspersed with uppercase letters in a random fashion. People with agraphia often prefer writing in print instead of cursive, and their writing may appear illegible to anyone else.
Many agraphics experience pain in their arm or hand while writing. They may also have muscle spasms while writing, hold a writing implement strangely or in an awkward position, and write very quickly or (more rarely) very slowly.
