Cerebral edema is a medical condition characterized by the accumulation of excess fluid in the brain, leading to swelling. This swelling can increase pressure within the skull, potentially causing damage to brain cells and affecting normal brain function. Common causes of cerebral edema include head injuries, infections, and certain medical conditions like stroke or tumors. Symptoms of cerebral edema may vary but often include headaches, confusion, seizures, and difficulty with coordination or balance. Diagnosis typically involves imaging techniques such as CT scans or MRI to visualize the swelling. Treatment focuses on addressing the underlying cause and may involve medications or surgical interventions to reduce pressure in the brain.
