Clinical neurophysiology is a branch of medicine that analyses the central and peripheral neural systems by observing bioelectrical activity, both spontaneous and induced. It includes pathophysiology research as well as clinical strategies for diagnosing disorders affecting both the central and peripheral nervous systems. In the discipline of clinical neurophysiology, tests aren't restricted to those performed in a lab. It is regarded as a follow-up to a neurology consultation.
Stroke is the third largest cause of death and the most common cause of acquired neurologic disability. Excitotoxicity starts a series of processes that contribute to tissue death during ischemic stroke, very soon after the onset of the localized perfusion deficit. It is usual in daily clinical practice to be asked to establish a stroke prognosis soon after the index event. This activity necessitates caution and knowledge. Clinical severity is the most powerful predictor of stroke outcome, but age, infarct volume and location, etiology, revascularization treatment, and comorbidities are other important factors.
