Validation of an Electroencephalograph Based Algorithm for Detection of Onset and Deterioration of Acute Ischemic Stroke by Comparison to NIHSS
Validation of an Electroencephalograph Based Algorithm for Detection of Onset and Deterioration of Acute Ischemic Stroke by Comparison to NIHSS
The purpose of this study is the validation of an Electroencephalograph based algorithm for
 detection of onset and deterioration of Acute Ischemic Stroke by Comparison to NIHSS.
Inclusion criteria study population

 1. Age > 18 years old.

 2. Acute stroke symptoms onset within 2 weeks of inclusion, and as proximate to event as
 possible and as long as there was no neurological deterioration (ΔNIHSS>4) from symptoms
 onset to inclusion.

 3. Patients with TIA lasting at least 5 minutes or minor acute ischemic stroke (NIHSS < 4
 at the time of enrolment)

 4. More than 3 of the following:

 Blood pressure >140/90 or unknown, Irregular heartbeat, Atrial Fibrillation, Smoker,
 Cholesterol >240 or unknown, Has Diabetes, Lack of physical exercise, Overweight, Has Stroke
 in the family

 OR between 4 and 6 of the following:

 Blood pressure 120-139/80-89, Unknown Irregular heartbeat, Atrial Fibrillation, Trying to
 quit smoking, Cholesterol 200-239, Borderline Diabetes, Some exercise, Slightly overweight,
 Not sure if Stroke occurred in family

 Exclusion criteria study population

 1. Intracranial hemorrhage on admission by CT.

 2. Previous major hemispheric stroke.

 3. Patients with pure sensory symptoms,

 4. Significant movement disorder.

 5. Local skull or skin affliction which prevents sensor application.

 6. Any known condition which in the opinion of the investigator may interfere with the
 protocol implementation.
