Chorea is a medical term used to describe a group of movement disorders characterized by involuntary, rapid, irregular, and uncontrollable muscle contractions or jerking movements. The term chorea is derived from the Greek word "khoros," meaning dance, as the movements associated with chorea appear similar to a dance.
Chorea can be classified into two main types: Sydenham's chorea, which is associated with rheumatic fever and typically affects children, and Huntington's chorea, a hereditary condition that usually begins in adulthood. However, chorea can also manifest as a symptom of various other underlying conditions, such as certain infections, metabolic disorders, drug reactions, or as a result of brain damage.
The involuntary and unpredictable nature of the muscle movements in chorea can range from mild to severe, and may affect any part of the body. These uncontrollable motions can include twitches, writhing, jerking, grimacing, or even purposeless and flowing movements. Chorea can also lead to difficulties in maintaining balance and coordination, affecting a person's ability to perform daily activities.
Treatment for chorea aims to manage the underlying cause whenever possible. This may involve medications to control the abnormal movements, physical therapy to improve motor function, and supportive measures to enhance quality of life. In some cases, chorea may resolve spontaneously, while in others, it may be a chronic condition that requires ongoing management. Regular monitoring by a healthcare professional is important to ensure appropriate care and to address any associated complications.
