I am fortunate? to have full time nursing in our home. My wife has Parkinson's disease and I have vascular dementia. Last weekend, I was standing in the kitchen and I was feeling lightheaded and unsteady. I braced myself against the corner of the countertop. However, I lost consciousness and slumped to the floor and tipped over and banged my forehead on the tile floor. I was fortunate that the injuries were quite minor. But it was a wake up call that such a thing can happen. Now I ask my nurse to assist me going to the kitchen or to bed.
