Quote:Researchers said the drug took effect after several days. Once established, the improvements were long-lasting, although after three months the circuits in the brain showed a decline in activity, Garner said.
I wonder if this means that whatever improvement that is going to happen will happen within three months, and that will be the maximum level of improvement that is achieved.
This is a little worrisome. I wonder if it would be the most ethical thing to improve a person's cognition, so that they learned how to function at one level, knowing that it would then regress after a certain amount of time. Although I guess if you were disabled and had the opportunity to achieve normalcy for even a small amount of time, most people would take that opportunity, no matter how short lived it might turn out to be.
In the case of people with Down's Syndrome though, since there are physical manifestations of the condition that make the person look different, I wonder how the change to normal cognition would affect their emotional health. A friend of mine did a study and found that the more severely mentally challenged a person was, the less prone they were to depression about their condition, due to the simple fact that they were not aware of how different they were or appeared to others in society. She found that those who had only slight mental impairments were more prone to depression, because they were very aware of the fact that they were different and were looked at and treated as such in social situations.
I think there'd be a lot of ethical questions around this, but I think it's interesting and promising research.
