Hypoxic ischemic encephalopathy (HIE) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, and is often a complication of cardiac arrest or profound hypotension. This can result in poor outcomes including significant impairments in memory, cognition, and attention.

In the context of sparse literature reports on chronic delirum following cardiac arrest related HIE, we report a case of a 59 year old male patient with normal premorbid functioning who developed chronic confusional state following a hypoxic insult to the brain subsequent to cardiac arrest and try to highlight the challenges encountered during his clinical course and management.

This case highlights the presence of chronic delirium following hypoxic ischaemic encephalopathy, an unfortunate consequence of cardiac arrest. It also highlights the problems encountered in managing such patients.
