Hypergraphia was first studied as a symptom of [[temporal lobe epilepsy]], a condition of reoccurring seizures caused by excessive neuronal activity, but it is not a common symptom among patients.  Less than 10 percent of patients with temporal lobe epilepsy exhibit characteristics of hypergraphia.{{medical citation needed|date=December 2013}}  Temporal lobe epilepsy patients may exhibit irritability, discomfort, or an increasing feeling of dread if their writing activity is disrupted.<ref>{{cite journal |vauthors=van Vugt P, Paquier P, Kees L, Cras P |title=Increased writing activity in neurological conditions: a review and clinical study |journal=J.

Most temporal lobe epilepsy patients who suffer from hypergraphia can write words, but not all may have the capacity to write complete sentences that have meaning.<ref name="Yamadori" />
