Interhemispheric Fissure Diseases

Interhemispheric fissure diseases refer to a range of medical conditions that affect the area between the two halves of the brain, known as the interhemispheric fissure. These conditions can vary widely in their causes, symptoms, and treatments. Understanding these aspects is crucial for early detection and effective management.
