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...
CNS Depressants: Alcohol and Nicotine01:27

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
Antiepileptic Drugs: GABAergic Pathway Potentiators01:18

Antiepileptic Drugs: GABAergic Pathway Potentiators

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 their...
Antiepileptic Drugs: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

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: Modulators of Neurotransmitter Release Mediated by SV2A Protein01:20

Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein

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...
Antiepileptic Drugs: Potassium Channel Activators01:20

Antiepileptic Drugs: Potassium Channel Activators

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.
Ezogabine has gained approval as an adjunctive treatment...

Epilepsy combined with alcohol use significantly increases mortality risk. This risk is higher for Black individuals, highlighting the need for tailored care and further research into influencing factors.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • Alcohol's complex relationship with epilepsy includes lowering seizure thresholds and potential epileptogenesis.
  • Chronic alcohol misuse can lead to neuronal injury and neurotransmitter dysregulation.
  • The long-term mortality impact of alcohol use in people with epilepsy (PWE) is not well understood.

Purpose of the Study:

  • To evaluate all-cause mortality risk in individuals with epilepsy based on alcohol consumption.
  • To stratify mortality risk by race/ethnicity in the context of epilepsy and alcohol use.

Main Methods:

  • Utilized data from the 2008-2018 National Health Interview Survey (NHIS) linked to the National Death Index (NDI).
  • Included U.S. adults aged 18+; PWE and alcohol use determined via self-report.

  • Employed Kaplan-Meier survival analysis and adjusted Cox proportional hazards models.
  • Main Results:

    • Alcohol use among PWE was linked to increased all-cause mortality (adjusted HR=1.40).
    • Alcohol use without epilepsy did not show elevated mortality risk after adjustment.
    • The epilepsy-alcohol combination significantly increased mortality in Black individuals, but not White individuals.

    Conclusions:

    • Combined epilepsy and alcohol use is associated with higher all-cause mortality than alcohol use alone.
    • Observed racial disparities in mortality risk necessitate further investigation.
    • Integrated clinical care and research into genetic, biological, and social determinants are crucial for improving epilepsy outcomes.
