Throughout human history scientists wondered what a disease is, and how they can prevent it. There are different types of diseases. Some diseases are spread by microbes and viruses, and some are genetic, also called disorders. Genetic disorder is a disease that is caused by an abnormality in one's DNA. The abnormality, such as mutation, may occur in the single gene as well as in the whole chromosome or in a set of chromosomes. [9] One of the genetic disorders that greatly influence human life is Huntington Disease. Huntington Disease (HD), also called Huntington Chorea, is a brain disorder resulted from a gene mutation in protein called huntingtin. The mutation in huntingtin causes a progressive degeneration of the neurons in the basal ganglia. The word "chorea" comes from Greek, and means "dance" in Latin. It refers to the uncontrollable movements of the afflicted individual. Even though the disorder is named after George Huntington, he was not the first scientist who witnessed this disease. His famous paper "On Chorea", which was submitted by him in 1872, was the first paper that described Chorea in details. Much of the information for Huntington's paper was drawn from his father's and grandfather's written observations, both physicians who had described the involuntary shaking in patients. The paper gained Huntington instant notability because he was able to clearly point to the genetic inheritance as the mode of transmission, and he also noticed that the first symptoms usually appear in the adult age and are accompanied by a mental decline as well. It is due to these significant observations and conclusions that "Huntington's Disease" bears George Huntington's name. [6] Nowadays, approximately 30,000 people in the United States suffer from HD, with another 15,000 at risk of developing this disorder. It is also known that the onset of the symptoms of HD is usually between the ages of 30 and 50; although in 10% of cases, the onset of the disorder is developed...
