Seven years ago, I realized there was something very wrong with my wife of four decades. I did not know what it was. In the beginning, I didn't consider it might be dementia. Lena had known the risk factors and done all the right things to avoid such an outcome. Ironically, while a graduate student at Berkeley, she had refused to use the drugs that were readily available, stating firmly that she would do nothing to damage her brain, since it was the only one she would ever have.
