Thanks for your replies. My wife has extensive damage to the right anterior temporal lobe along with frontal lobe damage. We have recently been told that she may have damage to capilleries within her brain possibly as a result of the 3 invasive brain operations she has had, the first to put a drain into the brain, secondly to position a shunt to drain fluid and finally a coiling operation. The aneuryism was finally located in December 2010 at the right rear of her head, close to the carotid artery. She has short term memory loss and has difficulty in finding her way around even familiar places, getting lost within her own home. However all is not doom and gloom, as she can be extremely well on a good day and close to the person she was prior to the haemorrhage. She is well capable of doing any tasks she wishes on these days but struggles with motivation, concentration and attention. The main difficulty is the 24 hour turn around in personality and behaviour.
