<<Disclaimer: Verify this information before applying it to your situation.>> My most noticeable response to trace amounts of gluten is a fuzzymindedness that lasts for several hours. In this state, I have difficulty with thinking that requires planning and tracking a sequence of activities, and I seem to have trouble focusing my attention to do any complex analytic reasoning. There also might be some mild depression, but I generally don't notice this as an unusual state until it has gone away (and I'm thinking clearly again). I figured out that this was a gluten response when I realized that it occurred most often after I had eaten pancakes for breakfast, using flour from questionable sources. My thinking would clear dramatically some time in the early afternoon. Since I began grinding my own flour, the problem has become rare. As a cognitive psychologist, I would like to see more research done on the cognitive consequences of celiac disease. Nancy Jackson <[log in to unmask]>
