Background:
A large body of evidence suggested that disruption of neural rhythms and synchronization of
brain oscillations are correlated with variety of cognitive and perceptual processes. Cognitive deficits are common
features of psychiatric disorders that complicate treatment of the motivational, affective and emotional symptoms.
Objective:
Electrophysiological correlates of cognitive functions will contribute to understanding of neural circuits
controlling cognition, the causes of their perturbation in psychiatric disorders and developing novel targets for treatment
of cognitive impairments.
Methods:
This review includes description of brain oscillations in Alzheimer’s disease, bipolar disorder, attentiondeficit/hyperactivity disorder, major depression, obsessive compulsive disorders, anxiety disorders, schizophrenia and
autism.
Results:
The review clearly shows that the reviewed neuropsychiatric diseases are associated with fundamental changes in
both spectral power and coherence of EEG oscillations.
Conclusion:
In this article we examined nature of brain oscillations, association of brain rhythms with cognitive functions
and relationship between EEG oscillations and neuropsychiatric diseases. Accordingly, EEG oscillations can most likely
be used as biomarkers in psychiatric disorders.
