My OH was started on Olanzapine for psychosis at 10mg April 1st and brought down to 5mg quickly mid June (to be maintained until September). He still believes the delusions he had prior to starting medication, but is not developing new ones. Should I be concerned? They were obviously ‘real’ to him at the time so seem to have formed solid memories. Psychosis is as a result of TBI (ironically also causing memory issues, but the crazy stuff seems to stick)
