Altered mental status
Type: Symptom
Definition
A sudden onset of profound confusion, disorientation, or dangerous lethargy.
Clinical Details
In severe, invasive cases, the bacteria breach the blood-brain barrier, triggering an aggressive, purulent inflammation of the brain tissues and meninges. This acute meningoencephalitis severely disrupts normal cognitive processing and cerebral electrical activity. It is a dire neurological symptom indicating an immediate, life-threatening crisis requiring urgent intervention.
