A Discourse on Hypergraphia and other writing pathologies, not omitting left-handedness and mirror writing.

Writing, a highly specialised motor activity integrally linked to language, is an intrinsic activity of our species and has played a huge part in the progression of civilisation. Being unable to read and write in today’s world is a huge liability. In this review, we look at issues related to writing including handedness, agraphia, hypergraphia, mirror writing, the role of pathology, psychiatric illness and artistic talent. Case studies include the prophet Ezekiel, Arthur Inman, Leonardo da Vinci and Vincent van Gogh. The study of writing is important and deserves further attention.
