Insights

Cefepime antibiotic can cause reversible encephalopathy, a severe brain condition. This study highlights a unique EEG pattern of triphasic waves associated with this cefepime-induced encephalopathy in seven patients.

Area of Science:

  • Neurology
  • Pharmacology
  • Infectious Diseases

Background:

  • Cefepime is a broad-spectrum, fourth-generation cephalosporin antibiotic.
  • It is frequently used for severe hospital-acquired infections.
  • Recent reports indicate potential for severe, reversible cefepime-induced encephalopathy.

Purpose of the Study:

  • To describe seven cases of reversible cefepime-induced encephalopathy.
  • To characterize a peculiar electroencephalogram (EEG) pattern associated with this condition.
  • To explore the link between EEG abnormalities and nonconvulsive status epilepticus.

Main Methods:

  • Case series reporting on seven patients.
  • Clinical and electrophysiological assessments, including EEG.
  • Analysis of EEG patterns and correlation with clinical presentation.

Main Results:

  • Seven patients presented with reversible cefepime-induced encephalopathy.
  • A distinct EEG pattern of semiperiodic diffuse triphasic waves was observed.
  • EEG abnormalities were associated with nonconvulsive status epilepticus in these patients.

Conclusions:

  • Cefepime can induce a specific, reversible encephalopathy.
  • The characteristic EEG pattern of diffuse triphasic waves is a key finding.
  • This encephalopathy may be linked to nonconvulsive status epilepticus, warranting further investigation.

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Seizures l: Introduction

Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...
Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
Seizures: Classification01:13

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
