Global Synchronization Index as an Indicator for Tracking Cognitive Function Changes in a Traumatic Brain Injury...

Area of Science:

• Neuroscience
• Medical Imaging
• Rehabilitation Medicine

Background:

• Traumatic brain injury (TBI) frequently leads to prolonged cognitive impairment.
• Cognitive deficits significantly impede rehabilitation and functional recovery after TBI.
• Assessing cognitive function is crucial for tailoring rehabilitation plans and monitoring progress.

Purpose of the Study:

• To evaluate the utility of advanced neuroimaging techniques for assessing cognitive function in a TBI patient with severe impairment.
• To demonstrate a novel approach for cognitive function analysis when conventional methods are insufficient.

Main Methods:

• Analysis of electroencephalography (EEG) using the global synchronization index.
• Application of low-resolution brain electromagnetic tomography (LORETA).
• Case study of a 77-year-old male patient with TBI and severe cognitive impairment.

Main Results:

• The combined EEG and LORETA analysis provided insights into cognitive function.
• These advanced methods offered a viable alternative for evaluation where conventional tests were inadequate.
• The case highlights the potential of these techniques in complex TBI scenarios.

Conclusions:

• Electroencephalography with global synchronization index and LORETA can aid in evaluating cognitive function after traumatic brain injury.
• These methods offer a promising avenue for managing patients with severe cognitive impairment, facilitating rehabilitation planning and assessment.
