At age 11 my sister was in a car accident and as a result was left permanently brain damaged. Shes able to walk and talk to about the level of 11/12yo but has a short memory span. She has three shunts in her head at the moment, all placed over 10 years ago. She is otherwise healthy.

My problem is that over the past few weeks she has been going through moments where she seems totally out of it, as in she is very very slow moving and it takes a lot of calling to her to bring her back to functioning, its like going into a deep day dream but its happening very frequently. It seems to happen mostly when she has been taken out of her routine i.e. on holidays or trips. When shes back in her normal routine shes fine, back to herself.

I was just wondering if this could have anything to do with the shunts? Could they be draining less frequently due to possibly less activity when shes not at "work" 3 days a week?

Or could this be more of a mental thing? Shes 35 and has been in a 3 day a week centre for 10+ years so its not a new routine or anything.

Thanks for any feedback x
