That is so wonderful that your son is doing so much better!
I think confusion also occurs because in a way, there are (at least) two things that could be considered “lack of insight” to consider:
- The psychotic experience itself, which almost by definition leads to “lack of insight” (i.e. the belief in the auditory hallucinations, etc.), and
- The ability to reflect on the experience later on (when the brain is in a different state) and to make the assessment that “Those experiences weren’t real” (which is probably due to other brain pathways, most likely in the prefrontal cortex)
The term “anosognosia” could be used for both of these states, which makes it confusing.
I think Dr. Amador’s work tries to address situation #2 (people who never have “insight”, even when in a different mental state such as achieved by medication).
If you think about it, though, both states potentially can vary quite a bit, which I’d think can lead to the changes in insight Maggotbrane mentions. Some people might have completely “normal” (i.e. neurotypical) wiring/development of the brain circuits that allow good self-monitoring while in a non-symptomatic or mildly symptomatic state, some might have some mild structural differences here (that allow a degree of self-monitoring) and some might have significant structural differences.
So I think we are dealing with two different categories (the severity of symptoms as well as the ability to self-monitor).
Severity of symptoms can vary within an individual (i.e. symptoms can wax and wane over time with an overall course that is improving vs. deteriorating) as well as between individuals.
And the ability to self-monitor varies a lot between individuals (and probably is relatively “set” by adulthood, although brains are amazing things, so I’d say that improvements in the ability to self-monitory certainly are theoretically possible and potentially [we don’t really know] facilitated by activities that develop/strengthen these abilities, such as CBT and other psychosocial [i.e. non-medication based] treatments).
It has been interesting watching my husband experience auditory hallucinations vs. ideas of reference, as he can become quite upset with me due to both processes but he manifests it differently.
When he experiences an auditory hallucinations of me saying something critical, he will just glare and me and does not try to address it.
When he misperceives something I actually say as an attack (e.g. when he is more symptomatic, he thinks that if I accidentally come up with the wrong word for something, that I am doing this to bother him and/or to “set him up” somehow), he will glare and me but then will say something about it to me.
So although he has never had any awareness of auditory hallucinations and although both of these experiences (the auditory hallucination of my saying something vs. me actually saying something) clearly trigger some auditory circuits in his brain, it is obvious to me that he does experience inner vs. outer voices in different ways. My guess is that these differences are one of the things that people with “insight” are able to recognize when their symptoms are not too severe. Sadly, my husband can never tell the difference.
I have a pretty strong family history of schizophrenia myself and I had the experience of having a fixed delusion when in my 20’s. I had no idea it was a delusion at the time and fortunately I was aware that I was very stressed and I started psychotherapy. I did not share the delusion with my therapist, not because I was trying to hide it but because although it was quite distressing to me, it really did somehow exist in a different place in my mind. Therapy went well, I gained tools for coping with stress, and the delusion eventually (I don’t know when) just went away. I did not even think about it until some experiences a few years later reminded me of it and then I realized if for what it was and felt like perhaps I had had a pretty close brush with a psychotic break myself. But clearly certain circuits in my brain work well, as I was able to recognize the experience as a delusion once I was past it. So my guess is that even if I had had a psychotic break and lost touch with “reality”, I would have had insight into what had happened later one, once my brain was in a different state again. Although clearly, this is just a guess.
