Summary

Survivors of attempted suicide by hanging may experience neurological deficits. Despite severe brain dysfunction indicated by burst-suppression electroencephalography (BS-EEG), some patients recover with minor cognitive impairments.

Background:

Hanging is a common suicide attempt method.
Unsuccessful attempts can lead to spinal fractures, motor/cognitive deficits, and seizures.
Post-anoxic brain dysfunction is a significant concern in survivors.

Observation:

A case study of a 25-year-old male survivor of attempted hanging is presented.
The patient exhibited a burst-suppression electroencephalography (BS-EEG) pattern post-anoxia.
Clinical diagnosis and consciousness assessment were performed in the post-comatose stage.

Findings:

The patient's consciousness gradually improved.
Neuropsychiatric assessment revealed memory deficits, attention deficits, and executive dysfunction one month post-discharge.
Severe brain dysfunction indicated by BS-EEG is a poor prognostic factor, yet recovery is possible.

Implications:

This case highlights the potential for neurological recovery despite severe EEG abnormalities after attempted hanging.
Understanding long-term cognitive outcomes is crucial for patient management and rehabilitation.
BS-EEG findings, while indicative of severe brain injury, do not always preclude functional recovery.
