Summary
Pediatric epilepsy surgery offers seizure freedom for 76% of children. Factors like surgery type and pathology influence outcomes, while residual or distant epileptogenic zones can lead to persistent seizures.
Area of Science:
- Pediatric Neurology
- Neurosurgery
- Epileptology
Background:
- Focal epilepsy surgery is effective in children, but persistent seizures occur.
- Predictors of surgical success are often unmodifiable, hindering understanding of failure.
Purpose of the Study:
- To identify factors associated with persistent seizures after focal resective surgery in pediatric epilepsy.
- To analyze quantitative and qualitative data for a comprehensive understanding of surgical outcomes.
Main Methods:
- Retrospective cohort study of 110 children and adolescents undergoing focal resective surgery.
- Quantitative and qualitative analyses of factors linked to persistent postoperative seizures.
Main Results:
- 76% achieved seizure freedom (Engel Class I) at a mean 3.1-year follow-up.
- Temporal lobe surgery, specific pathologies (tumor, MTS), and lower preoperative seizure frequency predicted seizure freedom.
- Residual epileptogenic tissue (40%), distant zones (32%), and hemispheric syndromes (28%) were linked to persistent seizures (Engel Class II-IV).
Conclusions:
- High-resolution imaging and invasive studies can improve outcomes.
- Consider aggressive resection, including hemispherectomy for suspected hemispheric syndromes.
- Family counseling and reoperation are crucial for select cases.

01:24Epilepsy and Seizures: Overview
1.7K
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...

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.

01:13Seizures: Classification
2.4K
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:

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

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,...
