Overview
Learning Objectives
After this lesson, you should be able to: Trace normal CSF circulation and explain how obstruction or impaired absorption produces ventricular enlargement and neurological decline.
After this lesson, you should be able to: - Trace normal CSF circulation and explain how obstruction or impaired absorption produces ventricular enlargement and neurological decline. - Recognize age-specific findings in infants, children, adults, and patients with shunts. - Relate CT, MRI, cranial ultrasound, and shunt imaging to the clinical question. - Prioritize airway and neurological safety, urgent imaging, and neurosurgical escalation when hydrocephalus or shunt failure is suspected. - Distinguish normal-pressure hydrocephalus from dementia, Parkinsonism, infection, migraine, and common gastrointestinal explanations for vomiting.
