The editors of this book are professors who are engaged in research on areas that compromise the total healing of body and mind in this patient population. One particular component of the need for survivor care is the memory problems and cognitive deficits experienced by some. The condition has been given a nameactually many names, such as chemo fog, chemo brain, and others. These names reflect the belief that the cause of the problem is the chemotherapy that they received as part of their treatment. In some cases the chemo fog/chemo brain is transient while in others it is of longer duration. Little is known about this problem and that fact peaked our interest and motivated this book. Therefore this book is devoted to one aspect of survivor care: chemo fog/chemo brain.
