Epilepsy and Seizures: Overview01:24

Epilepsy and Seizures: Overview

367
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...

Psychosurgery01:30

Psychosurgery

132
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Seizures: Classification01:13

Seizures: Classification

683
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 Therapy01:30

Electroconvulsive Therapy

263
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...

Area of Science:

  • Pediatric Neurology
  • Neurosurgery
  • Epileptology

Background:

  • Refractory focal epilepsies in children are challenging to manage with medical or dietary therapies.
  • Epilepsy surgery is established for specific phenotypes like temporal lobe epilepsy and known lesions.
  • Emerging evidence suggests broader applications for epilepsy surgery.

Purpose of the Study:

  • To review the expanding role of epilepsy surgery in pediatric patients.
  • To examine the efficacy of surgery in traditionally non-surgical epilepsy cohorts.
  • To emphasize the importance of early surgical intervention.

Main Methods:

  • Review of accumulating evidence on epilepsy surgery outcomes.
  • Analysis of surgical utility in special pediatric epilepsy circumstances.
  • Examination of factors influencing seizure and cognitive outcomes.

Main Results:

  • Epilepsy surgery provides significant seizure freedom or control in pediatric refractory focal epilepsies.
  • Surgery is increasingly effective in rare genetic disorders, electrical status epilepticus in sleep, and very young patients.
  • Earlier surgical intervention, particularly for focal cortical dysplasia, leads to better seizure and cognitive outcomes.

Conclusions:

  • Epilepsy surgery is a highly effective treatment for refractory focal epilepsies in children.
  • The indications for pediatric epilepsy surgery are expanding beyond classical phenotypes.
  • Timely surgical intervention is crucial for optimizing long-term neurological outcomes in children with epilepsy.
