# Research progress of quantitative electroencephalography in post-ischemic stroke mental disorders

## TL;DR

This review explores how quantitative EEG helps monitor mental disorders after ischemic stroke, focusing on different time periods post-onset.

## Contribution

The paper systematically analyzes qEEG indicators across early, subacute, and chronic stages of ischemic stroke.

## Key findings

- qEEG indicators vary significantly across different post-stroke time periods.
- Power spectrum analysis is a prominent focus in current qEEG research.
- Key monitoring indicators for mental disorders have been identified in ischemic stroke patients.

## Abstract

Quantitative electroencephalography (qEEG) has significantly advanced in the field of neuroscience as a highly sensitive tool for routine monitoring following a stroke. It holds promise in diagnosing post-stroke psychiatric disorders and evaluating treatment outcomes. This review systematically examined published papers and thoroughly analyzed research findings on using qEEG indicators to monitor mental abnormalities in patients with ischemic stroke. The review covers key time periods, including the early stage (within 72 h), subacute stage (72 h to 1 month), and chronic stage (over 1 month) post-onset. The current evidence suggests that correlation indicators from electroencephalography (EEG) monitoring vary across different time periods, with Power spectrum analysis is a current research hotspot. This review summarizes and analyzes specialized studies on utilizing these qEEG indicators for monitoring and evaluating mental disorders in ischemic stroke, identifying key monitoring indicators highlighted in current research.
