Lateral Sulcus Lesions

Lateral sulcus lesions refer to damage or abnormalities in the brain’s lateral sulcus, a groove located on the side of the brain. These lesions can result from various causes and can lead to a range of symptoms affecting different aspects of an individual’s functioning. Understanding the causes, symptoms, diagnosis, and treatment options for lateral sulcus lesions is crucial for effective management and improving quality of life.

The lateral sulcus, also known as the Sylvian fissure, is a prominent groove that separates the frontal and parietal lobes of the brain from the temporal lobe. Lesions in this area refer to any abnormalities or damage that occur within or around the lateral sulcus.

Causes of Lateral Sulcus Lesions:
