Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

268
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

570
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: GABAergic Pathway Potentiators01:18

Antiepileptic Drugs: GABAergic Pathway Potentiators

587
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: Glutamate Antagonists01:14

Antiepileptic Drugs: Glutamate Antagonists

493
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...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

913
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Antiepileptic Drugs: Potassium Channel Activators01:20

Antiepileptic Drugs: Potassium Channel Activators

262
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...

Area of Science:

  • Neurology
  • Psychiatry
  • Epidemiology

Background:

  • Psychiatric comorbidities (PC) are more prevalent in epilepsy patients than the general population.
  • Understanding the main PC and their associations is crucial for comprehensive epilepsy care.

Purpose of the Study:

  • To identify the primary psychiatric comorbidities associated with epilepsy.
  • To investigate the relationship between these comorbidities and demographic/clinical epilepsy features.

Main Methods:

  • A retrospective study analyzed 140 adult epilepsy patients.
  • Data collected included demographics, seizure characteristics, epilepsy type, etiology, brain injury, AEDs, and PC.

Main Results:

  • 67.1% of patients had PC, most commonly depression (22.8%), anxiety disorder (17.8%), psychosis (10%), dementia (9.2%), and bipolar affective disorder (8.5%).
  • A significant association was found between PC and epilepsy seizure control (p<0.009).
  • Specific comorbidities showed no significant relationship with factors like brain damage, education, epilepsy type, etiology, sex, or epilepsy duration.

Conclusions:

  • Epilepsy is significantly associated with psychiatric comorbidities, particularly depression and anxiety disorders.
  • Lower educational attainment was noted compared to the general population.
  • The findings highlight the need for integrated mental health care in epilepsy management.
