Differences in the perivascular spaces in the brain may serve as a biomarker for patients with epilepsy, assisting clinicians in determining the impact of the disorder, according to a comparison of MRI images from healthy controls and patients.
- Researchers used 7T magnetic resonance imaging to evaluate the brains of 21 patients with epilepsy and 17 healthy controls.
- Perivascular spaces were marked with the use of Osirix image analysis software.
- Investigators calculated the asymmetry index for each region of the brain and reported a maximum asymmetry index for patients and controls.
- Significant differences were found in the maximum asymmetry index between patients with epilepsy and controls (P=.016).
- In nearly 3 of 4 patients (72%), the area or lobe of the brain that displayed the maximum perivascular space asymmetry was also the area that contained the suspected area for the onset of seizures.
