Cady: Hydrocephalus Mistaken for Psychiatric Decline
Cady's escape from restraints exposes a neurologic clue that changes the diagnosis.
In Plain English
Cady may not simply be refusing psychiatric care; fluid pressure in her brain is affecting how she walks, thinks, and behaves.
What Happened in the Episode
The clue appears only after restraints are removed and she walks, which is a bad-process/good-outcome tension the episode explicitly notes.
Clinical Concept
Hydrocephalus, enlarged ventricles, gait disturbance, headache, behavioral symptoms, CSF pressure, VP shunt, and psychiatric mimic.
What ER Teams Would Evaluate
A real team would combine psychiatric safety care with neurologic exam, gait assessment, imaging, and neurosurgical review.
Treatment and Management Overview
Management may include safety precautions, CT/MRI, CSF diversion by shunt, rehab/follow-up, and reassessment of psychiatric diagnosis after neurologic treatment.
What TV Gets Right
The episode shows that objective gait and headache clues should challenge a purely psychiatric explanation.
What TV Compresses
It compresses shunt candidacy testing and the pace of neuropsychiatric recovery.
