Pediatric Epilepsy: Current Perspectives and Emerging Therapies

Abstract

0.5–1% of children worldwide suffer from epilepsy, a widespread neurological condition that affects people of all genders and demographics. It is a collection of disorders rather than a single illness that is typified by frequent, erratic seizures brought on by aberrant brain activity. These seizures can take many different forms, such as convulsions, sensory or behavioral abnormalities, or loss of consciousness. Recurrent unprovoked seizures, a high likelihood of recurrence, or an epileptic syndrome are the criteria used by the International League Against epileptic (ILAE) to describe epilepsy. Patients' neurological, emotional, and social well-being are greatly impacted by epilepsy, which is caused by neuronal hyperexcitability. Seizure type, EEG results, and related neurological characteristics determine classification. All things considered, epilepsy is a complicated condition with a wide range of causes and symptoms. In children, epilepsy and Attention Deficincy Hyperactivity Disorder (ADHD) often co-occur; approximately 30–40% of children with epilepsy also have ADHD. There are two types of epileptic seizures: focal and generalized. Automatisms, atonic or tonic episodes, clonic jerks, spasms, hyperkinetic movements, or myoclonus are examples of motor symptoms that can accompany focal seizures. Non-motor symptoms include autonomic changes, behavior arrest, cognitive disturbances, emotional changes, or sensory abnormalities. Absence seizures, myoclonic seizures, atonic seizures, tonic seizures, and tonic-clonic seizures are examples of generalized seizures that affect both hemispheres of the brain. This categorization aids in the diagnosis, management, and comprehension of epileptic seizure patterns. A common neurological condition in children, epilepsy is most common in the first year of life and is more common in low- and middle-income nations, where the majority of cases go untreated. The six main categories of its causes are structural, genetic, infectious, metabolic, immunological, and unknown. An imbalance between neuronal excitation and inhibition causes aberrant electrical activity during seizures, which can extend to different parts of the brain. Ion channel malfunction, neurotransmitter imbalance, and altered neuronal circuitry are some of the factors that lead to epileptogenesis and can have long-term repercussions on cognition, particularly following protracted or frequent seizures. When assessing epilepsy, a physical examination is crucial. This includes measuring blood pressure, looking for signs of neurocutaneous syndromes on the skin, and looking for anomalies in the skull that can point to underlying neurological conditions. Electroencephalography (EEG), neuroimaging, and genetic testing are used to diagnose epilepsy in children. Sleep EEG is crucial for focal epilepsies and epileptic encephalopathies. EEG is an easy-to-use method for identifying aberrant cortical excitability. While genetic testing, including next-generation sequencing, has identified over 265 genes associated with epilepsy, increasing the identification of genetic epilepsies, neuroimaging detects structural abnormalities in the brain. Antiepileptic medications including carbamazepine, ethosuximide, and levetiracetam are used in treatment; each is customized for a particular type of seizure and age group while taking side effects and effectiveness into account. An alternate strategy is offered by dietary therapy, especially the ketogenic diet, which lowers seizure frequency by altering neurotransmitter activity and brain metabolism. Together, these therapeutic and diagnostic approaches allow children with epilepsy to be Effecetiveiy managed.
