J Stroke

A J Stroke is a medical sign seen during a neurological exam, indicating a problem with one side of the brain, often due to a stroke or brain injury. When a person tries to move their eyes or head toward the affected side, their eye movement is limited, and the eye may turn or drift in the opposite direction, creating a pattern that resembles the letter "J". This sign helps doctors identify which side of the brain is affected and guides diagnosis and treatment planning.
