parietal lobe epilepsy true Parietal lobe epilepsy is a relatively rare form, occurring in about 5 percent of all epilepsy patients, and affects the part of the brain responsible for touch perception, sensory information and visual perception (distinguishing amongst objects). The parietal lobe also is involved in language, writing and math skills. It can occur at any age and affects males and females at an equal rate. Causes of parietal lobe epilepsy include head trauma, difficulties during childbirth, stroke and tumor, though as many as 20 percent of parietal lobe epilepsy outcomes are of unknown origin. http://www.case.edu/EpSO.owl#ParietalLobeEpilepsy simple focal seizure
