Hi.
From the query I can understand that she is having memory impairment. There are various kinds of memory impairments such as anterodrade, retrograde and global memory loss.
Do not panic over these symptoms, as they can be controlled.
First she needs to be evaluated completely and started on medication to stop the progression of memory loss.
Next Steps

Try puzzles and mind games
Try spending time outdoors, such as a park
Try new hobbies
