Abstract

JACAS CABRERA, Angela; ODUARDO AGUILAR, Mabel Rosa  and  VERDECIA AGUILAR, Merlin. Quantitative electroencephalogram alterations according to coherency in patients with Alzheimer dementia. Multimed [online]. 2021, vol.25, n.2, e1768.  Epub Mar 01, 2021. ISSN 1028-4818.

Introduction:

Alzheimer dementia is a clinical syndrome characterized by a persistent and acquire cerebral dysfunctions.

Objective:

identify alterations in quantitative electroencephalograms according to interhemispheric coherency was our objective.

Methods:

a descriptive study with transversal cortes was carried out in Carlos Manuel of Cespedes hospital in Bayamo of Granma province, in the period of January (2016) to May (2018). We determinated the electroencephalographic variables: bands and interhemispheric coherency. We used statistical methods with a parametric and no parametric tests according our muestric.

Results:

the age group of 60 to 64 years and the female sex predominated. There were significant differences regarding interhemispheric coherence in the four frequency bands taking into account the age groups, sex and brain lobes (p˂0.01)..

Conclusions:

It is possible to identify alterations in the quantitative electroencephalogram in relation to interhemispheric coherence in patients with Alzheimer's disease, allowing to establish differences regarding sex and the different brain lobes for each frequency band. Characterizing the disease from the electroencephalographic point of view.

Keywords : Quantitative electroencephalograms; Interhemispheric coherency; Alzheimer dementia.
