Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

350
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

659
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:

Cerebrum: Anatomical Overview I

3.1K
The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...

Lobes of the Cerebrum

1.9K
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....

Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

721
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Parkinson's Disease: Overview01:15

Parkinson's Disease: Overview

808
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Area of Science:

  • Neurology
  • Neuroscience
  • Epileptology

Background:

  • Frontal lobe seizures (FLS) are common and challenging to evaluate.
  • Frontal lobe epilepsy (FLE) is the second most frequent focal epilepsy localization.
  • Pharmacoresistant FLE may be treated with resective surgery.

Purpose of the Study:

  • Correlate seizure semiology with brain anatomy and electrophysiology for presurgical localization.
  • Investigate the hierarchical functional organization of the frontal lobe during seizures.
  • Explore the role of etiology and genetics in FLS for improved patient selection and outcomes.

Main Methods:

  • Intracerebral recording using stereoelectroencephalography (SEEG).
  • Detailed analysis of ictal motor and emotional semiology.
  • Correlation of semiological features with anatomical and electrophysiological data.

Main Results:

  • Ictal semiology reflects a rostro-caudal functional organization axis in the frontal lobe.
  • Motor and emotional signs help distinguish between frontal sublobar regions.
  • SEEG-based correlations improve presurgical localization.

Conclusions:

  • Frontal lobe seizure semiology is crucial for presurgical evaluation and localization.
  • Understanding seizure expression and underlying etiologies can optimize surgical candidate selection.
  • A genotype-phenotype approach may complement existing methods for defining FLS spectrum and improving prognostication.
