A 9-year-old girl who endured cyber-bullying because of her designation of Huntington's disease has died. Kathleen Edwards' assurance prefab domestic word in 2010 when a former close posted pictures on Facebook that pictured the then 7-year-old Edwards above a set of crossbones, and one with the slight female's parent, Laura Edwards, who died of Huntington's disease in 2009, in the blazon of the inexorable farmhand. The former someone, Jennifer Petkov, also allegedly betrothed a casket to her cart, tagged the object "Death Machine," and chisel it around the neighbourhood honking the hooter after LLaura Edwards' death, according to CBS Detroit.

Huntington's disease (HD) is a neurodegenerative genetic disorder that affects muscle coordination and leads to cognitive decline anddementia. It typically becomes noticeable in middle age. HD is the most common genetic cause of abnormal involuntary writhing movements called chorea, and indeed the disease used to be called Huntington's chorea. It is much more common in people of Western European descent than in those of Asian or African ancestry. The disease is caused by an autosomal dominant mutation on either of an individual's two copies of a gene called Huntingtin, which means any child of an affected parent has a 50% risk of inheriting the disease. In the rare situations where both parents have an affected copy, the risk increases to 75%, and when either parent has two affected copies, the risk is 100% (all children will be affected). Physical symptoms of Huntington's disease can begin at any age from infancy to old age, but usually begin between 35 and 44 years of age. About 6% of cases start before the age of 21 years with an akinetic-rigid syndrome; they progress faster and vary slightly. The variant is classified as juvenile, akinetic-rigid or Westphal variant HD.

The Huntingtin gene normally provides the genetic information for a protein that is also called "Huntingtin". The mutation of the Huntingtin gene codes for a different form of the protein, whose presence results in gradual damage to specific areas of the brain. The exact way this happens is not fully understood. Genetic testing can be performed at any stage of development, even before the onset of symptoms. This fact raises several ethical debates: at what age is an individual considered mature enough to choose testing, do parents have the right to have their children tested, and managing confidentiality and disclosure of test results. Genetic counseling has developed to inform and aid individuals considering genetic testing and has become a model for other genetically dominant diseases.

Symptoms of the disease can vary between individuals and among affected members of the same family, but the symptoms progress predictably for most individuals. The earliest symptoms are a general lack of coordination and an unsteady gait. As the disease advances, uncoordinated, jerky body movements become more apparent, along with a decline in mental abilities and behavioral and psychiatricproblems. Physical abilities are gradually impeded until coordinated movement becomes very difficult. Mental abilities generally decline intodementia. Complications such as pneumonia, heart disease, and physical injury from falls reduce life expectancy to around twenty years after symptoms begin. There is no cure for HD, and full-time care is required in the later stages of the disease. Emerging treatments can relieve some of its symptoms.

Self-help support organizations, first founded in the 1960s and increasing in number, have been working to increase public awareness, to provide support for individuals and their families, and to promote research. The Hereditary Disease Foundation, a research group born out of the first support organization, was instrumental in finding the gene in 1993. Since that time, many new research discoveries have been made and understanding of the disease is improving. Current research directions include determining the exact mechanism of the disease, improving animal models to expedite research, clinical trials of pharmaceuticals to treat symptoms or slow the progression of the disease, and studying procedures such as stem cell therapy with the goal of repairing damage caused by the disease.
