Hypergraphia

Example of graphorrhea: a letter written by schizophrenic Emma Hauck while institutionalized in a mental hospital; many of her letters consist of only the written words "come sweetheart" or "come" repeated over and over in flowing script

Hypergraphia is a behavioral condition characterized by the intense desire to write or draw. Forms of hypergraphia can vary in writing style and content. It is a symptom associated with temporal lobe changes in epilepsy and in Geschwind syndrome. Structures that may have an effect on hypergraphia when damaged due to temporal lobe epilepsy are the hippocampus and Wernicke's area. Aside from temporal lobe epilepsy, chemical causes may be responsible for inducing hypergraphia.
