<<Disclaimer: Verify this information before applying it to your situation.>> Vance and Mary are absolutely correct - I've heard all the same things, also. My daughter who was recently diagnosed with Celiac is suffering from psychosis right now. ( her dx. is schizoaffective disorder which is a combo of bipolar and schizophrenia - we are told that she may actually grow out of this.) We are Irish. My grandmother who was from Ireland lived on cake and breads and was schizophrenic. I wish I had know 13 years ago what I know now. None of my children would ever have ingested gluten. Since the 1920's doctors have known that a gluten free diet is helpful to schizophrenics, but these days we just jump right to medications without giving diets a try. ( at least in the management of psychotic illnesses other than Autism) My daughter's psychiatrist said that the diet may help 30% where the medications may help 90% and that it is just easier to take meds. My hope is that a combination of diet and medications will help 100% - or 99%. My fear is that the damage of nearly 13 years of gluten ingestion has permanently damaged my little girls brain and the effects will be irreversible. Laurie in New York
