Focal Cortical Dysplasia, West Syndrome

Disease Overview

Focal Cortical Dysplasia (FCD) is a congenital neurological disorder characterized by abnormal brain cortex development, leading to treatment-resistant epilepsy. West Syndrome is a severe epilepsy syndrome affecting infants, marked by characteristic seizures, developmental regression, and distinctive brain wave patterns.

Disease Category

• Focal Cortical Dysplasia: Neurological disorder, Developmental brain malformation, Epilepsy syndrome
• West Syndrome: Pediatric epileptic encephalopathy, Neurodevelopmental disorder

Synonyms

• Focal Cortical Dysplasia: Cortical Dysplasia, Malformative Cortical Development
• West Syndrome: Infantile Spasms, Generalized Flexion Epilepsy, Hypsarrhythmia Syndrome

Signs & Symptoms

Focal Cortical Dysplasia: - Recurrent, medication-resistant seizures - Focal neurological deficits - Cognitive impairment - Potential motor skill limitations - Sensory processing difficulties

West Syndrome: - Characteristic infantile spasms (sudden, brief muscle contractions) - Developmental regression or stagnation - Hypsarrhythmia on EEG (chaotic brain wave pattern) - Potential intellectual disability - Increased irritability - Feeding difficulties

Causes

Focal Cortical Dysplasia: - Genetic mutations (MTOR, DEPDC5 genes) - Prenatal neuronal migration disruptions - Potential environmental factors during brain development - Possible genetic mosaicism

West Syndrome: - Genetic mutations - Metabolic disorders - Chromosomal abnormalities - Brain malformations - Perinatal brain injuries - Tuberous Sclerosis Complex - Infections affecting brain development

Affected Populations

• Focal Cortical Dysplasia:

  • Prevalence: 1-2 per 1,000 individuals
  • Most commonly diagnosed in children
  • No significant gender predilection

• West Syndrome:

  • Incidence: 1 in 2,000-4,000 live births
  • Typically onset between 3-12 months
  • Affects both genders equally

Disorders with Similar Symptoms

• Tuberous Sclerosis
• Lennox-Gastaut Syndrome
• Polymicrogyria
• Early Infantile Epileptic Encephalopathy
• Sturge-Weber Syndrome

Diagnosis

Focal Cortical Dysplasia: - High-resolution MRI - Electroencephalography (EEG) - Genetic testing - Neuropsychological assessment

West Syndrome: - Clinical symptom evaluation - Video EEG monitoring - Brain imaging (MRI, CT) - Genetic screening - Metabolic disorder testing

Standard Therapies

Focal Cortical Dysplasia: - Surgical resection - Anti-epileptic medications - Vagus nerve stimulation - Ketogenic diet - Neurodevelopmental rehabilitation

West Syndrome: - ACTH therapy - Oral corticosteroids - Vigabatrin - Ketogenic diet - Developmental interventions - Physical and occupational therapy

Clinical Trials and Studies

• Ongoing research at major epilepsy centers
• Genetic therapy investigations
• Novel anti-epileptic drug trials
• Neuroplasticity and rehabilitation studies
