Shamini A/P Arasalingam, Ahmad Faizal Shamsuddin, Hatta Sidi, Hjh Rabai'ah bt Mohd Salleh


Objective: Several cases of suicide attempt by charcoal burning producing CO have been reported in Malaysia. This case report highlights a case of delayed delayed neuropsychiatry sequelae (DNS) in CO poisoning.

Method: We report a young Chinese homemaker who presented with DNS who was detained in a Malaysian forensic psychiatric ward.

Results: After approximately two weeks of admission, in a familicide attempt, she had started to exhibit subtle changes in her behaviour, including social withdrawal, impaired memory, and there was lack of emotional distress.

Conclusion: We report an interesting DNS as one of the two forms of chronic sequelae of CO poisoning, whereas the other type of neuropsychiatric sequelae is the persistently progressive type.
