Electroencephalographic mechanisms of cognitive improvement induced by cerebellar stimulation in patients with mild cognitive impairment

The cerebellum relative power spectrum and functional connectivity in the theta band of resting-state EEG holds promise as sensitive biomarkers for the early detection of MCI. Bilateral cerebellum 5 Hz rTMS enhanced theta band cerebellar relative power and functional connectivity between the cerebellum and the left frontal lobe, thereby augmenting the compensatory role of the cerebellum under cognitive impairment conditions and improving cognitive function in MCI.
