    Insights

    This study on West syndrome in 130 children found symptomatic cases in 95.4%, with prenatal factors in 57%. Treatment guided by EEG and MRI, primarily with valproates, improved seizures and cognitive function.

    Area of Science:

    • Pediatric Neurology
    • Epileptology

    Background:

    • West syndrome is a severe infant epilepsy.
    • Symptomatic forms and hypsarrhythmia are common.
    • Prenatal factors contribute significantly to etiology.

    Purpose of the Study:

    • To analyze clinical and EEG characteristics of West syndrome.
    • To evaluate the effectiveness of EEG and MRI-guided treatment.
    • To assess the role of valproates in management.

    Main Methods:

    • Study included 130 children aged 1.5 months-2 years with West syndrome.
    • EEG and MRI were used for diagnosis and treatment planning.
    • Valproates were the primary therapeutic agents (mono- and polytherapy).

    Main Results:

    • 95.4% of cases were symptomatic West syndrome.
    • 87% showed hypsarrhythmia on EEG (86.7% modified variants).
    • Treatment reduced seizures, improved EEG, and stabilized cognitive function.

    Conclusions:

    • EEG and MRI are crucial for effective West syndrome treatment.
    • Valproate therapy, guided by diagnostics, improves outcomes.
    • Early intervention stabilizes intellectual decline and aids recovery.

    Electroconvulsive Therapy

    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 years,...

    Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

    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...
