My Mom (92) has recently had problems with falling backwards... She was actually holding onto her walker when she said she felt herself falling backwards without any warning. Her doc believes it could be related to a certical problem (or the artery in the back of her neck - not the carotids - is blocked). The doc balked at having an MRI done, because "there wouldn't be anything to do about it & it tends just to freak people out & make them fearful of "stroking out". Any thoughts/info? I found an article online on this, which was called Backward Disequilibrium - "BD" - but her doc just cut me off as soon as I mentioned the source & said "you can find anything online, so let's not go there!"
