Transcript of Huntington'sDisease
Huntington’s Disease is an incurable, hereditary brain disorder. It is a brain disorder for which there is no accurate treatment. Nerve cells become damaged, causing various parts of the brain to worsen. The disease affects movement, behavior and cognition (thinking) - the affected individuals' abilities to walk, think, reason and talk are gradually eroded to such a point that they eventually become entirely reliant on other people for their care. Huntington's disease has a major emotional, mental, social and economic impact on the lives of patients, as well as their families. George Huntington was the first person to provided a comprehensive description of adult-oneset in 1872, he was only 22 years old at that time.
Disorder's Inheritance and Symptoms
Huntington's disease is caused by an inherited defect in a single gene, which means that a person needs only one copy of the defective gene to develop the disorder with the exception of genes on the sex chromosomes, a person inherits two copies of every gene one copy from each parent. A parent with a defective Huntington gene could pass along the defective copy of the gene or the healthy copy. Each child in the family, therefore, has a 50 percent chance of inheriting the gene that causes the genetic disorder. The gene of Huntington's is located in 4P102.
Huntington's disease affects an estimated 3 to 7 per 100,000 people of European ancestry. The disorder appears to be less common in some other populations, including African Americans and Japanese. In the United States alone, about 30,000 people have Huntington's disease; estimates of its prevalence are about 1 in every 10,000 peoples
This condition is inherited in an autosomal dominant pattern which means one copy of the altered gene in each cell is sufficient to cause the disorder. An affected person usually inherits the altered gene from one affected parent.
Mood changing, which can be noticed by family members. Uncontrolled movement of the arms, legs, head, face and upper body. Depression, anxiety, uncharacteristic anger and irritability; decline in thinking and reasoning skills, including memory, concentration, judgment and ability to plan and organize. Leading a person to repeat the same question or activity over and over.
Doctors analyze DNA to detect the chromosomes if their have no symptoms exposed yet. Neurlogical and psychiatric evaluation, brain imaging/tests electroencephilaogram.
Although there are no curing treatments, there are treatments for certain symptoms to slow them down like tetrabenazine.
