Summary
Body asymmetry is a useful indicator for diagnosing localisation-related epilepsy. This finding can also help lateralise seizure origins in partial onset seizures, aiding diagnostic management strategies.
Area of Science:
- Neurology
- Clinical Neuroscience
Background:
- Differentiating localisation-related epilepsy from generalised epilepsy is crucial for effective diagnostic and management strategies.
- Body asymmetry (BA) is frequently observed in patients with localisation-related epilepsy syndromes.
Purpose of the Study:
- To investigate the relationship between clinically detectable body asymmetry and the electro-anatomic characteristics of epilepsy.
- To determine if body asymmetry can aid in differentiating epilepsy types and lateralising seizure origins.
Main Methods:
- A retrospective study of 337 patients with seizure disorders was conducted.
- Body asymmetry was documented, and 56 patients were excluded due to various non-epileptic conditions.
- The association between body asymmetry and epilepsy type (localisation-related vs. generalised) was analyzed.
Main Results:
- Body asymmetry was present in 88 of 282 eligible patients (31.2%).
- Patients with localisation-related epilepsy showed significantly higher rates of body asymmetry (41.5%) compared to those with generalised epilepsy (18.75%).
- In partial onset seizures, body asymmetry lateralisation was concordant with seizure origin in 75.9% of cases.
Conclusions:
- Clinically detectable body asymmetry is a valuable clue for diagnosing localisation-related epilepsy.
- Body asymmetry may assist in lateralising the seizure origin in partial onset seizures, improving diagnostic accuracy.

01:28Major Somatic Sensory Pathways
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
01:13Seizures: 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:

01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
01:20Seizures l: Introduction
Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...
01:19Seizures ll: Types
Seizures are sudden bursts of abnormal electrical discharge in the brain that interfere with normal function. They are commonly divided into three groups: focal seizures, generalized seizures, and other types that do not fit neatly into either category.Focal SeizuresFocal seizures begin in a single brain region. When awareness is preserved, they are called focal aware seizures and may cause sensations such as tingling, unusual smells, or flashing lights. When awareness is impaired, they are...
01:22Epilepsy ll: Types
Recurrent seizures, stemming from abnormal electrical activity in the brain, are the defining characteristic of epilepsy, a chronic neurological condition. Because seizure features vary greatly, epilepsy is classified using two systems: by seizure type and by epilepsy syndromes. These classifications enable clinicians to describe seizure patterns and select suitable treatment strategies.I. Classification by Seizure Type1. Focal EpilepsyFocal epilepsy begins in one hemisphere of the brain.
