Summary
Psychogenic nonepileptic seizures (PNES) are complex neurological events diagnosed via video-EEG monitoring. Treatment is multifaceted, with less than 40% of adults achieving seizure freedom within five years.
Area of Science:
- Neurology
- Neuroscience
- Psychiatry
Background:
- Psychogenic nonepileptic seizures (PNES) are frequently managed in epilepsy centers.
- The underlying neurobiology of PNES remains incompletely understood.
- Diagnosis typically involves multidisciplinary assessment and data synthesis.
Purpose of the Study:
- To provide a concise review of the current literature on PNES.
- To cover key aspects including definition, diagnosis, epidemiology, clinical features, treatment, and prognosis.
Main Methods:
- Literature review of current scientific publications on PNES.
- Synthesis of information regarding diagnostic criteria and treatment modalities.
- Analysis of epidemiological data and prognostic factors.
Main Results:
- Video-electroencephalogram (EEG) monitoring is the most reliable method for diagnosing PNES.
- Treatment for PNES is phased and requires a multidisciplinary approach.
- Prognosis indicates that fewer than 40% of adult patients achieve seizure freedom within five years post-diagnosis.
Conclusions:
- PNES diagnosis relies heavily on objective monitoring, particularly video-EEG.
- Effective PNES management necessitates comprehensive, phased treatment strategies.
- The long-term prognosis for adults with PNES suggests a significant portion may not become seizure-free.

1.9K
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:

01:24Epilepsy and Seizures: Overview
1.5K
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...

01:18Antiepileptic Drugs: GABAergic Pathway Potentiators
1.5K
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.

01:20Antiepileptic Drugs: Potassium Channel Activators
873
Ezocgabine or retigabine, an antiepileptic drug of remarkable efficacy, has revolutionized the management of seizures. It is a potassium channel activator, explicitly targeting the family of Q subtype potassium channels. It enhances the transmembrane potassium currents, regulating neuronal excitability. This action stabilizes the resting membrane potential, a pivotal factor in mitigating the hyperexcitability that characterizes epilepsy.

1.0K
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...

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...
