Psychotic disorders are frequently accompanied by significant and disabling cognitive losses. These cognitive difficulties can persist even when other symptoms (delusions, hallucinations) are well controlled by anti-psychotic medications. Well-researched cognitive problems include difficulties with short term and working memory, focusing, sequencing (essential for planning), judgment and problem solving.
You may not have heard much about these problems. Unfortunately, too often neither have the people who have them. Though people with Alzheimer’s or traumatic brain injuries (or almost all other disorders) are informed about their situations, there are very few psycho-education programs for adults who develop schizophrenia.
