Abstract

Brain coherence is interpreted as the degree of synchrony between two or more brain regions with respect to their
frequency values. In a practical way, it has proven to be useful for the evaluation of the functional connections
between the different brain areas, either during the resting state or during cognitive processing. Structurally,
coherence is thought to be mediated by short and long cortico-cortical association fibers, as well as
cortico-subcortical fibers. In this regard, the independent affectation of these types of fibers in dementia-type
pathologies has been demonstrated. Thus, for example, an affectation of the corticosubcortical association fibers
in Multi-infarct Dementia (MID) has been reported against an affectation of the long cortico-cortical association
fibers in Alzheimer's Dementia (AD). Through the coherence analysis it is possible to discriminate between these
two pathologies with 90% certainty.
