I am a 63 year old women that was diagnosed with this horrible condition. I don’t know if I believe in this condition. I was so active all my life and out of the blue I woke up with water in my right ear and a few days later I was staggering so I just assume it was an ear problem. I have been all over the place to get a diagnosis. Finally the Mayo Clinic tells me that I have Functional Gait Disorder. My only symptoms are: I become lightheaded when I stand at least 90 percent of the time when I stand. I stagger when I walk but not all the time. Also I become lightheaded when I walk at least 50 percent of the time when I walk. I know some of my triggers like when I look up, down and after I work out like after I get finished walking on the Treadmill and when I also weight train. When I walk on the treadmill I do not experience any symptoms. Does this sound like Functional Gait Disorder? Not to me.
