Neurological evolution of severe baclofen intoxication: from brain death mimic to recovered brain function.

Patients with brain death have by definition irreversible and complete loss of brainstem reflexes. Before a definite diagnosis of brain death can be confirmed, all potential confounders must be thoroughly excluded. Baclofen intoxication is a rare cause of brain death mimic characterised by transient deep coma and absence of brainstem reflexes and might be mistaken with brain death. We report the case of a female patient in her 70s who ingested baclofen with suicidal intent and was admitted with a deep coma and loss of all brainstem reflexes and a spontaneous burst-suppression pattern in the electroencephalography which resolved over 10 hours. After a state mimicking brain death for 6 hours, the patient experienced complete recovery. Severe baclofen intoxication can mimic brain death clinically and is associated with temporary pathological electroencephalographic findings. Awareness of this toxidrome is crucial, as appropriate management can lead to full recovery.
