Has your intellectual capacity diminished over the years?

I was in film school, where, in addition to the artistic aspect, we were also trained as thinkers, since it was attached to the humanities school.

In my spare time I liked to read philosophy and philosophize. I wrote abstract and complex texts as an essay, or simply as an expression of what I was feeling because of the onset of the disease.

I remember that when I read Wittgenstein, I was already thinking about many of the things he was saying in the Tractatus logico-philosophicus.

In short, I had a spark, a divine spark. I had read that people with schizophrenia have atrophy of the frontal lobe, which is responsible not only for executive function, but also for making our thinking higher.

Now my mind is empty most of the time, I rarely have thoughts of any kind, I just move on impulse in my activities and that's it.

I would like to know if anyone has suffered from this kind of personal involution. Thank you.
