Magnetoencephalography assessment of evoked magnetic fields and cognitive function in subcortical ischemic vascular dementia patients

► We analyzed the correlations between SEF, AEF and cognitive function in SIVD patients by MEG. ► The latency of M20 was delayed and ECD strength was increased in VCI-ND and SIVD patients. ► The M100 latency of AEF was delayed in SIVD and VCI-ND patients. ► The changes of SEF and AEF are correlation with the impairment of cognitive function in SIVD patients.
