Hyponatremia, serum sodium <135 mEq/L, is the most common electrolyte abnormality affecting ∼30% of hospitalized patients [1]. An infrequent yet serious complication of hyponatremia is hyponatremic encephalopathy. Hyponatremia can result in an influx of water to the intracellular space. This results in cellular swelling that can lead to cerebral edema and encephalopathy. Patients at highest ris...

Sepsis associated encephalopathy (SAE) is a poorly understood condition that is associated with severe sepsis and appears to have a negative influence on survival. The incidence of encephalopathy secondary to sepsis is unknown. Amino acid derangements, blood-brain barrier disruption, abnormal neurotransmitters, and direct CNS effect are possible causes of septic encephalopathy. Research has not...

Encephalopathy resulting from the administration of levetiracetam (LEV) is a rare occurrence. We experienced a patient receiving LEV treated with valproic acid (VPA) for partial seizures with secondary generalization, following which she developed hyperammonemic encephalopathy and showed complete recovery after the drug was withdrawan. LEV is able to promote hyperammonemic encephalopathy when a...

1. Episodic (precipitant-induced) encephalopathy, commonly seen in the hospital setting, where a superimposed event is a key factor. 2. Persistent (chronic) encephalopathy, seen with extensive portal–systemic shunts and after portocaval shunt surgery or placement of transjugular intrahepatic portosystemic shunt (TIPS). 3. Minimal (subclinical) encephalopathy reflects alterations in cognitive fu...

Dear Editor, Cefasporins such as cefepime are beta-lactam antibiotics with a broad antimicrobial spectrum. They are commonly used as first-line agents in the treatment of many infections.1 Reversible encephalopathy is a known neurotoxic complication of cefalosporins.2 Previous case reports have documented triphasic waves on electroencephalography (EEG) in cephalosporin-induced encephalopathy.1-...

The anticonvulsant agent valproate (VPA) may cause hyperammonemic encephalopathy. Magnetic resonance imaging (MRI) and proton MR spectroscopic (MRS) findings in a patient with VPA-induced hyperammonemic encephalopathy are described. MRI showed a metabolic-toxic lesion pattern with bilateral T2-hyperintense lesions in the cerebellar white matter and in the globus pallidus. MR spectroscopic findi...

The encephalopathy that occurs in association with hemolytic uremic syndrome (HUS), which is caused by enterohemorrhagic Escherichia coli (E. coli), has a high mortality rate and patients sometimes present sequelae. We herein describe the case of a 20-year-old woman who developed encephalopathy during the convalescent stage of HUS caused by E.coli O26. Hyperintense lesions were detected in the ...

Objectives This study aimed to identify differences in absolute neutrophils, lymphocytes, and neutrophil-to-lymphocyte ratio between neonates with two forms of ischemic brain injury, hypoxic-ischemic encephalopathy, and acute ischemic stroke, compared to controls. We also aimed to determine whether this neutrophil/lymphocyte response pattern is associated with disease severity or is a consequen...

Wernicke's encephalopathy (WE) is a disease usually related to chronic alcoholism. The clinical diagnosis is often difficult to establish. MR imaging is a highly sensitive method for detecting lesions associated with Wernicke's encephalopathy. We report a case of atypical manifestation of hyperintense lesions on magnetic resonance imaging (MRI) in a 60-year-old male patient with Wernicke's ence...
