lifestyle
2

Neuroimaging Surveillance

Regular MRI or CT scans to monitor lateral ventricle size changes and assess for progression of underlying conditions. Imaging frequency determined by clinical presentation and suspected etiology.

monitoring
3

CSF Pressure Management

Pharmacological agents such as acetazolamide to reduce cerebrospinal fluid production when elevated intracranial pressure contributes to ventricular enlargement. May include diuretics for short-term management.

medication

Additional treatment options

Ventriculoperitoneal Shunting

Surgical placement of a catheter system to divert excess cerebrospinal fluid from the ventricles to the peritoneal cavity. Considered for progressive hydrocephalus or symptomatic intracranial hypertension.

surgical

Activity Modification and Head Elevation

Sleeping with head elevated and avoiding activities that increase intracranial pressure such as heavy lifting or straining. Gradual return to normal activities as symptoms improve.

lifestyle

Neuropsychological Support

Cognitive assessment and counseling to address memory difficulties, processing speed changes, or emotional adjustment related to neurological changes. Provides coping strategies and monitors for progressive cognitive decline.
