What are some causes of hemiplegia?

Hemiplegia refers to paralysis or abnormal movements on one side of a person, either the right or the left. The affected side, or hemisphere , may be completely paralyzed or weakened, or may move in stiff, stiff movements. Hemiplegia can be characterized by many other problems. For example, the use of one hand may be limited, there may be a problem with balance, speech may be affected, or there may be visual field problems.

Hemiplegia may be a disorder present at or around birth, or it may be acquired after birth. The underlying cause of hemiplegia is damage to the brain as a result of interrupted blood flow. This interruption can be caused by several factors.

There are many different types of hemiplegia. facial hemiplegia It is characterized by paralysis of a particular side of the face. cerebral hemiplegia It occurs when a brain injury cuts off blood flow to the brain. spastic hemiplegia it is characterized by paralysis together with spastic movements of the affected side. spinal hemiplegia It is caused by lesions that have formed in the spine.

The most common cause of hemiplegia is stroke. A stroke occurs when a blood clot forms and blocks normal blood flow or when a blood vessel ruptures, cutting off or stopping blood flow. Stroke is the leading cause of cerebral palsy, which is another major cause of hemiplegia. Perinatal strokes, which occur in babies within three days of birth, can cause cerebral palsy in children. Cerebral palsy limits work not specifically by total paralysis, but by uncontrollable spasms.

Another cause of hemiplegia can be the resulting interruption of blood flow to the brain due to injury to the motor centers of the brain. Excessive bleeding that accompanies some head injuries deprives the brain of blood or affects blood vessels through swelling. If a person sustains an injury to the right side of the brain, the left side of the body experiences paralysis or weakness. If the left side is affected, then the right side of the body will experience hemiplegia.

Hemiplegia is similar to another condition called hemiparesis but it is much more serious. Hemiparesis is usually characterized by one side of the body not being affected by paralysis, but by a less severe state of weakness.

It is difficult to prevent stroke and cerebral palsy in babies, so good prenatal care is essential to prevent this condition. Diabetics and those with high blood pressure and/or cholesterol are at high risk for stroke, as are those who are obese, smoke, do not exercise, and drink alcohol excessively.
