Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an observational study. Patients who fulfill all inclusion criteria and none of the exclusion criteria will be enrolled in the study, be neurologically evaluated and will go through a series of EEG recordings during their hospitalization. EEG recordings will be analyzed using proprietary computational analyses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The abnormal state of consciousness is difficult to define, measure and characterize. Many of the terms mean different things to different people, and may prove inaccurate when transmitting and recording information regarding the state of consciousness of a patient. Modern clinical assessments of level of consciousness such as the Glasgow Coma Scale (GCS) or the Grady Coma Scale, in addition to being subjective assessments, are incomplete and insufficient as they are based on assessment of responsiveness only.

An objective tool to asses a level of consciousness is therefore needed. Such a tool may be used to determine the level of consciousness independent of personal interpretation and/or variance between clinicians and provide consistency in assessment across patients and between medical facilities.

The Neurosteer system provides objective neurological biomarkers using a wearable easy-to-use affordable system. The system facilitate the capture and interpretation of EEG data with only a single patch of electrodes, attached on the subject's forehead. Neurosteer examination includes completing auditory tasks while measuring brain activity with the device. The data is analyzed using machine learning methods to produce biomarkers, enabling a report of the patient's activity in real time and offline. The examination is easy to preform and can be conducted in every clinic or in patients' homes.

In this study, research clinical staff (RCS) will identify potential subjects after being hospitalized in the department and will examine the eligibility of subject according to inclusion and exclusion criteria.

When a legal guardian is assigned, guardian will sign the Informed Consent Form (ICF). Otherwise, RCS will approach an independent physician who will be informed about the study and its goals. Independent physician will evaluate patient's eligibility for study. RCS will also inform patient's family/accompanying individuals on study's objective and design.

RCS will set up sanitized Neurosteer equipment at the patient's bed-side and record 72 consecutive hours of resting-state EEG. Level of consciousness will be assessed every 4 hours by the trained research personnel. Every 4 hours an auditory stimulation of 12 minutes will be played to the subject to assist in delirium assessment.

Level of consciousness will be assessed by validated screening tools (GCS) and the Neurosteer technology.

Patients

Patients who are hospitalized in Soroka University Medical Center (SUMC) Neurology department with a diagnosis of acute stroke

Neurosteer EEG recorder

Intervention Type DEVICE

The system is composed of hardware and software modules that facilitate the capture and interpretation of electrophysiological data as well as enable viewing the processed data in real time and offline. An electrode patch is attached on the subject's forehead to capture the electrophysiological signal. The signal is sent via low energy Bluetooth to an EEG Monitor. The signal is then sent via Wi-Fi to the cloud where the data is stored on a HIPAA compliant server. Data analysis performed in the cloud transforms the electrophysiological signal into easily readable data of brain activity.
