Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

1.6K
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...

Arboviral Encephalitis01:25

Arboviral Encephalitis

19
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Seizures: Classification

2.1K
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:

Antiepileptic Drugs: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

1.2K
Glutamate is a fundamental neurotransmitter in the central nervous system, playing a vital role in neuronal communication and various cognitive processes. Glutamate stands as the principal excitatory neurotransmitter in the brain. Its presence is crucial for the communication between neurons, underpinning essential processes such as synaptic transmission, neuronal excitability, and plasticity. These functions are vital for higher-order cognitive processes, including learning and memory. The...

Antiepileptic Drugs: GABAergic Pathway Potentiators01:18

Antiepileptic Drugs: GABAergic Pathway Potentiators

1.6K
γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
The key GABA pathway potentiators used in epilepsy management are as follows.
Benzodiazepines are a well-known class of drugs used for...

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein01:20

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

1.1K
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...

Summary
This summary is machine-generated.

Autoimmune epileptic encephalopathy, linked to neuronal antibodies, is treatable. Early diagnosis and immunotherapy improve outcomes, especially when antibodies target GABA-A receptors, often causing refractory seizures.

Area of Science:

  • Neuroimmunology
  • Neurology
  • Epileptology

Background:

  • Autoimmune epileptic encephalopathy (AEE) is a treatable neurological condition.
  • It involves neuronal antibodies in serum and cerebrospinal fluid.
  • Symptoms include seizures, neuropsychiatric issues, movement disorders, and cognitive decline.

Purpose of the Study:

  • To review the role of neuronal antibodies in epilepsy.
  • To assist clinicians in diagnosing and treating AEE.
  • To highlight the link between specific antibodies and seizure severity.

Main Methods:

  • Review of current literature on neuronal antibodies and epilepsy.
  • Analysis of antigen discovery methods identifying GABA-A receptor antibodies.
  • Examination of clinical studies on immunotherapy response.
  • Inclusion of in-vitro, in-vivo, and animal model data.

Main Results:

  • Antibodies to GABA-A receptor subunits are associated with severe refractory seizures.
  • These antibodies are found in a subset of epilepsy patients (<10%).
  • Neuroinflammatory features predict immunotherapy response.
  • Neuronal antibodies are confirmed as pathogenic and epileptogenic.

Conclusions:

  • Neuronal antibodies are a significant cause of AEE.
  • Early recognition is crucial due to potential underlying tumors.
  • Prompt treatment improves patient outcomes.
