Epilepsy and Seizures: Overview

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...

Seizures: Classification

Seizures: Classification

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: Modulators of Neurotransmitter Release Mediated by SV2A Protein

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...

Overview of Synapses

Overview of Synapses

A synapse is a specialized structure where two neurons connect, allowing them to pass an electrical or chemical signal to another neuron. It is the point of communication between neurons. The term "synapse" is derived from the Greek word "synapsis," which means "conjunction." The entire process of neural communication revolves around the synapse. When activated, a neuron releases chemicals known as neurotransmitters into the synapse. These neurotransmitters cross the synapse and bind to...

Antiepileptic Drugs: Glutamate Antagonists

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...

Integration of Synaptic Events

Integration of Synaptic Events

Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...

Area of Science:

Neuroscience
Neurology
Psychiatry

Background:

Neuroscience emerged in the 1950s as a multidisciplinary approach to studying the brain and neuropsychiatric disorders.
The collaborative study of neurological and psychiatric disorders has roots dating back to the 17th century and antiquity.
Epilepsy's historical understanding evolved from supernatural theories in Babylonian medicine to natural causation in the Greco-Roman period.

Purpose of the Study:

To describe the historical evolution of understanding epilepsy.
To trace the development of epilepsy from ancient beliefs to modern scientific concepts.
To highlight epilepsy's role as a bridge between neurology and psychiatry.

Main Methods:

Historical analysis of medical texts and theories related to epilepsy.
Tracing the separation of epilepsy from other convulsive diseases.
Examining the influence of neuropathology and cortical localization on epilepsy classification.

Main Results:

Epilepsy was initially attributed to supernatural causes before being recognized as a brain disorder.
The 19th century saw the separation of idiopathic and symptomatic epilepsy and the concept of seizures as electrical discharges.
The discovery of the electroencephalogram reinforced the understanding of seizures as electrical brain activity.

Conclusions:

Epilepsy has a long history, evolving from ancient beliefs to modern neurological and psychiatric understanding.
The study of epilepsy continues to inform our knowledge of brain function and neuropsychiatric disorders.
Epilepsy remains a critical area of study, bridging neurology and psychiatry due to its global impact and associated cognitive and psychosocial issues.
