Recent studies, however, have shown that several factors can interrupt this neurogenesis. These include stress and prolonged sleep deprivation (more than one day). The sleep disturbances encountered in AD could therefore suppress neurogenesis and thus impairing hippocampal functions. This would therefore contribute to diminished memory performances and the progression of AD. And progression of AD would aggravate sleep disturbances. It is a second vicious circle.
Keep a pen and paper next to your bed. If you're often kept awake by racing thoughts and worries and you tend to make to-do lists in your head, keep a pen or pencil and a small pad of paper handy and write them down. As you put each item down on paper, imagine yourself setting aside that concern. (Again, use a book light; don't turn on the overhead or a bright bedside light to write.)
