I was diagnosed with Parkinson's in October of 2007 and I have to have an MRI of my brain today because I have fallen 3 times recently. I don't feel faint the lights go out and I wake up as I am falling. I am terrified of MRI's. I don't like small places at all. My doctor gave me an Ativan to take an hour prior to the test. Have any of you ever had a panic attack during an MRI? Any advice?
