After suffering from a flu for a week, my mother became strange today. She is seeing and doing strange things. She saw people in the room that were not there and kept asking who they were. It is late night now as I write this and she acts like she is sewing something invisible on her bed. While she was normal the flu had her very very tired. Now she seems to be more active doing her "things". She will not sleep. Dementia? Temporary delirium? The meds she took were Nyquil Nighttime (1 tablet a day), aspirin (1 a day), loratadine (10mg a day) and losartin (50mg a day for high blood pressure). The loratadine and Nyquil were not taken the same days. I will take care of her, but want to know if this is a permanent or temporary condition.
