Septic Encephalopathy

Septic Encephalopathy

Every year, more cases of sepsis appear in intensive care units. The most frequent complication of sepsis is septic encephalopathy (SE), which is also the essential determinant of mortality. Despite many years of research, it still is not known at which stage of sepsis the first signs of SE appear; however, it is considered the most frequent form of encephalopathy. Patients have dysfunction of ...

Magnetic resonance imaging abnormalities with septic encephalopathy.

A 48 year old woman, status post renal transplantation six years earlier, died after a two week illness characterised by fever, recurrent seizures, and coma. Widespread abnormalities were seen on neuroimaging. A diagnosis of septic encephalopathy was established on postmortem. We describe the magnetic resonance imaging findings of bilateral basal ganglia, thalamic, cerebellar, brainstem, and ce...

Pathophysiology of septic encephalopathy - an unsolved puzzle

The exact cellular and molecular mechanisms of sepsis-induced encephalopathy remain elusive. The breakdown of the blood-brain barrier (BBB) is considered a focal point in the development of sepsis-induced brain damage. Contributing factors for the compromise of the BBB include cytokines and chemokines, activation of the complement cascade, phagocyte-derived toxic mediators, and bacterial produc...

Neurological Sequelae of Sepsis: I) Septic Encephalopathy

Septic encephalopathy (SE) or sepsis-associated delirium is the most common encephalopathy in ICU patients. It is defined by brain dysfunction due to systemic inflammatory response syndrome and extracranial infection. Clinically, acute impairment in level of consciousness and confusion are primarily defining symptoms. Precise clinical evaluation of brain function is crucial, although the necess...
