Overview

Hemiplegia is total paralysis of the arm, leg, and trunk on the opposite side of the body. Hemiplegia is more severe than hemiparesis, wherein one half of the body has less marked weakness.Hemiplegia and Hemiparesis may be congenital, or they might be acquired conditions resulting from an illness, an injury, or a stroke.
The most common cause of hemiplegia is stroke. Other causes of hemiplegia include spinal cord injury, specifically Brown-Séquard syndrome, traumatic brain injury, or disease affecting the brain.
The incidence of hemiplegia is much higher in premature babies than term babies. There is also a high incidence of hemiplegia during pregnancy and experts believe that this may be related to either a traumatic delivery, use of forceps or some event which causes brain injury.
Other causes of hemiplegia in adults include trauma, bleeding, brain infections and cancers. Individuals who have uncontrolled diabetes, hypertension or those who smoke have a higher chance of developing a stroke. Weakness on one side of the face may occur and may be due to a viral infection, stroke or a cancer.
