The symptoms are not very clear to merit a proper diagnosis. Loss of interest, decreased concentration and attention, feeling low and disturbed sleep or appetite are some of the signs of depression.  The confusion may be due to anxiety or preoccupation with other matters. She will require a detailed assessment by a Psychiatrist to come to any conclusion
