Cortical dysplasia is a condition where the brain’s outer layer, the cortex, doesn’t develop normally. This can lead to various neurological problems. Let’s explore this condition in simple terms, covering its types, causes, symptoms, diagnosis, treatment options, and prevention measures.
Types of Cortical Dysplasia:
- Focal Cortical Dysplasia (FCD): This type affects only certain areas of the brain’s cortex.
- Multifocal Cortical Dysplasia: It involves multiple areas of abnormal development in the cortex.
- Polymicrogyria: Characterized by excessive folding of the cortex, leading to a bumpy appearance.
Causes of Cortical Dysplasia:
- Genetic Factors: Inherited genes may play a role.
- Brain Injury: Such as head trauma during childbirth or accidents.
- Infections: Viral infections during pregnancy can affect brain development.
