Cortical diseases affect the outer layer of the brain, known as the cortex. This crucial part of the brain is responsible for many essential functions, including memory, attention, perception, and language. When the cortex is damaged or affected by disease, it can lead to a range of symptoms and complications. In this guide, we’ll explore the types, causes, symptoms, diagnostic tests, treatments, drugs, surgeries, preventions, and when to see a doctor for cortical diseases.
Types of Cortical Diseases:
- Alzheimer’s Disease: A progressive neurological disorder that affects memory and cognitive function.
- Parkinson’s Disease: A neurodegenerative disorder that primarily affects movement and can also impact cognition.
- Epilepsy: A neurological disorder characterized by recurrent seizures.
- Stroke: A medical emergency caused by interrupted blood flow to the brain, leading to brain damage.
- Multiple Sclerosis (MS): An autoimmune disease that affects the central nervous system, including the cortex.
- Brain Tumors: Abnormal growths of cells in the brain that can affect cortical function.
- Frontotemporal Dementia: A group of disorders characterized by progressive damage to the frontal and temporal lobes of the brain.
