Relating to, involving, or causing confusion; characterized by confusion or disorder.
From confusion + -al (relating to). Confusion derives from Latin confusio (act of mixing together), and -al is the adjectival suffix meaning 'relating to' or 'of the nature of.'
Doctors use 'confusional state' as a medical term for when patients are temporarily confused or delirious from illness, fever, or medication—it's not the same as dementia because it's reversible, which is why the specific term matters for diagnosis.
