Schizophrenia is known for causing memory problems, big and small. My working memory, basically short term memory that is automatic and subconscious, is not 100%, but too high to really be a problem. The only thing that makes me realize this is taking longer to get used to video game controls. Funny, really.
But you can strengthen the wiring of your brain my practicing memory tasks- this is proven to work, there’s a thread about neuroplasiticy Brain Plasticity and Recovery from Schizophrenia
and it has some hard science material about how you can improve your brain with your mind- my shrink is really into it, he says the way I logically use proofs to invalidate my delusions which happen once or twice a day is very good and says that I should experience less intrusive delusions as I do this. I shoot down delusions very quickly, I haven’t been truly delusional in a long time.
