does anyone know why those with epilepsy are more likely to develop a gluten allergy?

[Q.E.D]

The gluten allergy actually causes some forms of epilepsy:

In the Lancet recently (1) a consistent cohort of patients affected by drug-resistant epilepsy with cerebral calcifications where all cured when they were placed on a gluten-free diet. All had an atrophic jejunal mucosa, which recovered on a gluten free diet. Gluten intolerance is now a recognized cause of brain calcifications and epilepsy, of dementia, of psychiatric disturbances: many researchers believe that, in genetically predisposed subjects, gluten is not healthy for the brain function (2).
