I am not a nurse but a social psychologist and developing the practice and philosophy of concept-mapping for quite some years now. It is all about constructive recollection and personal memory management. When we can see situations from all sides, as they return across time one way or another, then they enable us to see sharper and understand better what we are dealing with all the time.
To study illnesses from one or many perspectives, using concept maps, using a free tool (no expiration date), use PMM personal memory manager. A demo video for writing a research paper with it is on http://www.pmm.nl/examples/examples.htm I would be happy to assist too. Best regards, Ron dW
