<s>[INST] My mother-in-law has terminal cancer and currently under the care of Hospice.  Mornings seem good when she has energy but later in the day, she will "doze" during a conversation and become confused.  She does not sleep long at night.  It appears she has "black eyes."  What does the black eyes mean and why can she just "doze" at not remember? [/INST] Black eyes can be due to head trauma caused by fall which is the common cause in hospice care.CT scan can be done to rule out it.Forgetfulness is quite common in elderly patients but ned to check out the medicine list which can be cause of diimentia. </s>
