Summary
Status epilepticus in central nervous system infections is often refractory, with over 24% of patients requiring multiple antiepileptic drugs. This condition is linked to higher mortality rates, especially in encephalitis cases.
Area of Science:
- Neurology
- Infectious Diseases
- Epileptology
Background:
- Status epilepticus (SE) in central nervous system (CNS) infections is understudied.
- Comprehensive evaluation of antiepileptic drug (AED) response in this population is lacking.
Purpose of the Study:
- To evaluate the efficacy of AEDs in patients presenting with SE secondary to CNS infections.
- To identify factors associated with refractory SE and mortality in this cohort.
Main Methods:
- Observational study at a tertiary care hospital in India.
- Included 37 adult patients with SE and CNS infection.
- Utilized clinical evaluation, MRI, and CSF analysis; categorized infections into encephalitis, meningitis, and granuloma.
Main Results:
- 24.3% of patients had refractory SE (RSE) after the second AED; 10.8% refractory to the third AED.
- Mortality was 29.7%, higher in patients with RSE.
- Encephalitis cases showed a trend towards poorer AED response.
Conclusions:
- Refractory SE in CNS infections is associated with significant mortality.
- AED response in SE due to encephalitis warrants further investigation.
- Timely and effective management of SE in CNS infections is crucial to reduce mortality.

01:20Seizures 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,...
01:19Encephalitis 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...
01:24Epilepsy 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...

01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:22Epilepsy ll: Types
Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.
01:30Electroconvulsive Therapy
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
