Data on brain volume and brain lesion-load MRI-acquired in patients with multiple sclerosis separated by the abnormalities found on the TBR.

Abbreviations: TBR = trigeminal blink reflex; AbLat = patients with delayed latencies on the TBR;AbEx = patients with enhanced R2c/R2 ratio and no latency abnormalities.aAll data regarding to volume and lesion-load (expressed as mean and SD values in mm3) were normalizedto the individual brain size using a correction factor (VSCALING).
