These approaches in the past have both resulted I think in an increased awareness of people’s cognitive strengths and cognitive limitations; that’s been good. Not so good is that things don’t generalize well. People learn some things in the hospital in a few rehab settings; they go home and it seems like they were never here. That’s been a big problem and typically we’ve thought in terms of what is actually happening here. We’ve thought that people were probably recruiting intact areas of cognitive function and preserved brain areas. Although we joked about it and we thought wouldn’t it be nice if we were actually fixing people’s brains we didn’t have a lot of support for that and we would actually kind of educate families and patients that that was not our agenda. Of course, we have some recent evidence increasing dramatically about brain changing due to some of the things we do. And recently there has also been a big meta-analysis of cognitive intervention with people with brain injuries and it looks like it does work in terms of function improving though not at work in terms of fixing people’s brains - we don’t know. To make a long story short, I’ve done this for a long time. A lot of people in rehab have. So we have a lot of opinions or gut feelings when somebody says I’m getting older and how do I keep my brain from having problems – how do I keep myself from having cognitive impairment.
