    Insights

    Gelastic epilepsy, a rare disorder, can manifest in newborns. This study reports two neonatal cases with hypothalamic masses, successfully managed with conservative treatment, showing no further neurological decline.

    Area of Science:

    • Neurology
    • Pediatrics
    • Epileptology

    Background:

    • Gelastic epilepsy is characterized by sudden, brief episodes of laughter or smiling.
    • First described in 1873, fewer than 100 cases have been documented globally.
    • Neonatal onset of gelastic seizures is exceptionally rare.

    Observation:

    • This report details the first two documented cases of gelastic epilepsy with onset in the immediate neonatal period.
    • Both infants presented with posterior hypothalamic mass lesions.
    • The presumed congenital origin of these lesions was investigated.

    Findings:

    • Both patients experienced gelastic seizures originating from posterior hypothalamic masses.
    • Conservative management was implemented for both cases.
    • Neither patient exhibited further neurological progression following treatment.

    Implications:

    • This study expands the understanding of rare epilepsy syndromes in neonates.
    • Highlights the association between hypothalamic lesions and early-onset gelastic seizures.
    • Suggests conservative treatment may be effective in managing this rare condition, preventing neurological deterioration.

    Epilepsy and Seizures: Overview01:24

    Epilepsy and Seizures: Overview

    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

    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:

    Antiepileptic Drugs: GABAergic Pathway Potentiators

    γ-aminobutyric acid or GABA, plays a pivotal role as an inhibitory neurotransmitter in the brain. GABA pathway potentiators, also known as GABAergic drugs, are a class of pharmaceutical agents designed to enhance the functioning of the GABAergic system. These medications primarily treat epilepsy, a neurological disorder characterized by recurrent seizures.
    The key GABA pathway potentiators used in epilepsy management are as follows.
    Benzodiazepines are a well-known class of drugs used for their...

    Inborn Errors of Metabolism

    Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

    Seizures 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,...

    Epilepsy 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.
