Subtle neuropsychiatric sequelae of carbon monoxide intoxication: two case reports

Area of Science:

• Neuroscience
• Psychiatry
• Toxicology

Background:

• Carbon monoxide (CO) intoxication is a common environmental hazard.
• CO poisoning can lead to a spectrum of neurological and psychiatric sequelae.
• Subtle neuropsychiatric abnormalities may be overlooked or misdiagnosed.

Purpose of the Study:

• To highlight the potential for subtle emotional and cognitive deficits after carbon monoxide intoxication.
• To emphasize the importance of comprehensive evaluation in suspected cases.
• To advocate for specific diagnostic and management strategies.

Main Methods:

• Case report of two patients with carbon monoxide intoxication.
• Description of sequential neuropsychological testing.
• Inclusion of psychiatric counseling in management.

Main Results:

• Both patients exhibited subtle yet significant emotional and cognitive impairments post-intoxication.
• Sequential testing revealed persistent or evolving deficits.
• Psychiatric counseling provided a framework for understanding and managing symptoms.

Conclusions:

• Neuropsychiatric abnormalities following carbon monoxide poisoning can be subtle and easily missed.
• Sequential neuropsychological testing is valuable for detecting and monitoring these deficits.
• Judicious psychiatric counseling is essential for effective patient management and recovery.
