That is definitely frustrating and I empathize with the parents for not fully understanding negative symptoms; I think this is really common due to it’s presentation. I would provide the family with many online resources about positive and negative symptoms and print out charts with lists of positive and negative symptoms so they can see both in the same context and in different formats. Sometimes being able to hold a piece of paper with a side by side chart is more tangible than words. Hopefully they will begin to understand that just like his positive symptoms are part of schizophrenia, so are his negative symptoms. Our EPI team also has a group just for parents where one of our clinicians provides education and the parents have the ability to liaise with their peers to talk about these issues which can help normalize these things for them.
