Digital Biomarkers in Neurology

Digital biomarkers are a set of characteristics and properties collected from digital health technology, which is measured as an indicator of the biological, pathological process and the response to any exposure or intervention which can be therapeutic

Secondary Stroke Prevention

Secondary stroke prevention decreases subsequent stroke and therefore disability.

Collateral Cerebral Circulation

Absence of collateral function due to hypoplasia or stenosis of collateral arteries may lead to a higher risk of stroke in patients with severe internal carotid artery occlusive disease

Posterior Cerebral Circulation

Posterior circulation of the brain consists of 2 vertebral arteries, 1 basilar artery, 2 posterior cerebral arteries and their branches.

Anterior Cerebral Circulatione

Anterior circulation of the brain comprises of internal carotid artery and its branches.

Acute Ischemic Stroke - Basics

Stroke is defined as “rapidly developed clinical signs of focal (or global) disturbance of cerebral function, lasting more than 24 h or leading to death, with no apparent cause other than of vascular origin”

Cerebral Blood Flow

During cerebral autoregulation, optimal perfusion pressure is maintained by changes in Cerebrovascular resistance. CBF is kept relatively constant through the change in vessel diameter at the CPP range of 40-140 mmHg. It is controlled by means of myogenic, metabolic, and neurogenic factors, and partial pressure of arterial blood gases (CO2 and O2), cerebral metabolism, and the autonomic nervous system are primary determinants of CBF.
