Congenital and acquired hemiparesis are neurological conditions that result in weakness or partial paralysis of one side of the body. Although less severe than hemiplegia, which leads to complete paralysis of one side, these two conditions are often discussed together due to their similarities. In the United States alone, it is estimated that approximately 70,000 children are born with or develop hemiparesis or hemiplegia, with a prevalence rate of one in 1,000.
Understanding Hemiparesis: Causes, Symptoms, and Impacts
Hemiparesis is a condition that occurs when one hemisphere of the brain sustains damage, leading to muscle weakness on one side of the body. Typically, this weakness affects the face and limbs. However, hemiparesis can also result in a range of additional physical, emotional, behavioral, and cognitive impairments. Depending on the specific hemisphere that experiences damage, an individual’s diagnosis may vary as right or left hemiparesis.
Causes of Hemiparesis
Hemiparesis can be caused by various factors, with some of the most common being cerebral palsy, multiple sclerosis, stroke, disease, infection, brain tumor, and traumatic head injury. It is important to note that there are two distinct types of hemiparesis: congenital and acquired.
Congenital hemiparesis refers to the condition in which a person is either born with it or develops it shortly after birth. It is estimated that approximately 80% of individuals with hemiparesis have this type.
On the other hand, acquired hemiparesis is developed later in life as a result of an event or disease. This type accounts for about 20% of all cases of hemiparesis.
