Technology of Intracranial Pressure Estimation by Single-Channel EEG in Brain Disease

Study Overview
=================
Brief Summary
-----------------
If intracranial pressure can be measured non-invasively using single-channel EEG, clinicians will be able to easily monitor changes in intracranial pressure in patients with brain diseases in the clinical setting. Therefore, a more efficient treatment plan can be established and the prognosis of patients with brain disease can be expected to improve in the long term.

Detailed Description
-----------------
Study Objectives: Accuracy evaluation of single-channel EEG-based estimated intracranial pressure and actual intracranial pressure in patients with brain disease It is intended to improve the accuracy by analyzing and upgrading the correlation and concordance of the single-channel EEG-based estimated intracranial pressure compared with the actual intracranial pressure measurement of the patient. Study design: Multi-center prospective clinical trial The study procedure was explained to the caregiver of the patient with brain disease admitted to the emergency room or intensive care unit, who was or will be implanted with an intracranial pressure monitoring device and informed consent was obtained. While the intracranial pressure monitoring device is being applied, EEG data and intracranial pressure data are simultaneously acquired by applying a single-channel EEG. EEG-based intracranial pressure prediction model and actual intracranial pressure comparison analysis are conducted to evaluate the prediction model and upgrade it.
