Specific neuroimaging findings
| Disease | Finding |
|---|---|
| Autism | Increased total brain volume |
| OCD | abnormalities in orbitofrontal cortex and striatum |
| Panic disorder | decreased volume of amygdala |
| PTSD | decreased hippocampal volume |
| Schizophrenia | Enlargement of cerebral ventricles |
| Huntington disease | hyperintensity in caudate region (T2 image) |
| Normal Pressure Hydrocephalus | Enlarged ventricles on MRI |
| Multiple Sclerosis | Periventricular hyperintensities (T2 image) |
| Pseudotumor cerebri | Shrunken ventricles |
A DaTscan is a form of functional neuroimaging that measures striatal dopamine transport and is useful as an ancillary test to confirm a diagnosis of Parkinson's disease.
