Hypergraphia

Hypergraphia is a behavioral condition characterized by the intense desire to write. Forms of hypergraphia can vary in writing style and content. It is a symptom associated with temporal lobe changes in epilepsy, which is the cause of the Geschwind syndrome, a mental disorder. 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.
