I did say 'can be'. The soldiers with PTSD whose depression has improved with small numbers of treatments did not simply suffer from a biological abnormality - their brains changed in response to stimulus, which is after all what we'd expect brains to do.
I do think brains should be viewed as different from most organs when we describe medical intervention, they are plastic to a degree other organs are not. If a diabetic could simply 'mutate' their pancreas to function normally with a single intervention, I think most would prefer that to taking insulin all their lives, even if the one intervention was distressing.
Brains actually can change in very dramatic ways. Most are for the worse of course, and we instinctively avoid any change in our mentality, but they are times when it is actually preferable.
