The Pathophysiology of Collateral Circulation in Acute Ischemic Stroke.

Cerebral collateral circulation is a network of blood vessels which stabilizes blood flow and maintains cerebral perfusion whenever the main arteries fail to provide an adequate blood supply, as happens in ischemic stroke. These arterial networks are able to divert blood flow to hypoperfused cerebral areas. The extent of the collateral circulation determines the volume of the salvageable tissue, the so-called "".

A clinical efficacy experience of Lacosamide on sleep quality in patients with Nocturnal Frontal Lobe Epilepsy (NFLE).

Background: Nocturnal frontal lobe epilepsy (NFLE) is a focal epilepsy with seizures arising mainly during sleep and characterized by complex motor behavior or sustained dystonic posturing. First described in 1981, it was considered a motor disorder of sleep and was indicated as nocturnal paroxysmal dystonia (NPD).
