Ventricular-brain ratio

[2] It is a common measure of ventricular dilation or cerebral atrophy in patients with traumatic brain injury or hydrocephalus ex vacuo.

[1] Generally, a higher VBR means a worse prognosis for recovering from a brain injury.

[3] For example, VBR is significantly correlated with performance on the Luria-Nebraska neuropsychological battery.

[4] Studies have found people with schizophrenia have larger third ventricles and VBR.

[5] Correlational studies have found relationships between ventricle-brain ratio and binge eating and inversely with plasma thyroid hormone concentration.

Example of enlarged lateral ventricles in schizophrenia.
