If she wants to sleep, I suggest you allow her to do so. Mom's doctor said that rest from the bleeds is the best medicine there is. Only when she is better, should she be encouraged to strengthen her brain (read, games, etc). When Mom would have her bleeds, I would bring her to my house and she slept on the bed in my office nearly all day (getting up for bathroom and nourishment only). It would usually take 3-5 days before she would be interested in being up a few hours at a time. Your wife needs her rest more than anything right now. She will get better.
