Example of enlarged lateral ventricles in schizophrenia.<unk>  <unk> , also known as the ventricle-to-brain<unk>  or ventricle-brain<unk> , is the<unk>  of total ventricle area to total<unk>  area, which can be calculated with planimetry from<unk>  imagining techniques such as CT scans. It is a common measure of<unk>  dilation or cerebral atrophy in patients with traumatic<unk>  injury or hydrocephalus ex vacuo.<unk>  also tends to increase with age. Generally, a higher<unk>  means a worse prognosis for recovering from a<unk>  injury. For example,<unk>  is significantly correlated with performance on the Luria-Nebraska neuropsychological battery. Studies have found people with schizophrenia have larger third ventricles and<unk> . Correlational studies have found relationships between ventricle-brain<unk>  and binge eating and inversely with plasma thyroid hormone concentration.
