With my father having just passed after battling dementia, and the fact that all four of his first cousins and my mother's grandfather had dementia, it is never far from my mind. This morning I remembered when my grandmother was in the hospital. Her sodium level was brought dangerously low. She suffered seizures and amnesia. The doctor said that the amnesia was caused by the dramatically low sodium levels and that it would likely clear up as the levels returned to normal. It did. While she did not have dementia, that leads me to a question. The one thing many older people have in common is a low sodium diet. If dangerous sodium levels can cause memory issues, can a lower level of sodium over an extended period of time cause damage that leads to dementia? While the answer is too late for my family, I ask this question for all the new and future patients that may be helped.
