Understanding Huntington's Disease

Understanding Huntington's Disease Diagnosis of Huntington's Disease Today, blood tests can be used to diagnose people with symptoms of suspicious Huntington's disease. In this test, we analyze the DNA in the blood sample and calculate the number of times the genetic code of Huntington's gene has repeatedly mutated. People with Huntington's disease usually have over 40 such "repeats"; people without it are 28 or less. If the number of iterations lies somewhere in between, a more extensive neurological and diagnostic test is required.

Huntington's disease is a hereditary disorder that gradually disappears or regresses nerve cells in a specific part of the brain. In 1872, an American physician George Huntington first explained Huntington's disease (HD) in detail and called "hereditary chorea" to emphasize some of its main features. Chorea 1 is a dance by the language of Greek, and represents the uncontrollable movement of dance in the HD crowd. The genetic nature of HD helps to distinguish it from other types of chorea that are infectious, metabolic or hormonal. By understanding the genetic characteristics of HD, finally, modern researchers can identify the cause of the disease - single genetic mutation or misspelling

Huntington's disease, often abbreviated as HD, is a brain disease that causes deterioration of brain neurons. Dr. George Huntington first discovered HD in 1872. HD was originally called Greek word Huntington disease. It means dancing and explains some of the symptoms of HD. There are three main symptoms, sports, cognition and psychosis. Movement symptoms include sudden muscle cramps, falls, difficulties in speaking, and difficulties with swallowing at a later time, resulting in extreme weight loss. Cognitive symptoms include difficulty learning new things, difficult tasks of multitasking, cumbersome priorities, and general difficult communication. HD psychiatric symptoms include mainly depression, anxiety and irritation, obsessive-compulsive disorder with certain activities, convulsions, and mania.

The symptoms of Huntington's disease usually occur between 30 and 50 years of age, but it may occur at an early age of 2 to 80 years. A prominent symptom of Huntington's disease is that the movement of the arm, leg, head, face, upper body can not be controlled. Huntington's disease can also lead to a decline in thinking and reasoning power including memory, attention, judgment, planning and organizational power. Scientists found defective genes that caused Huntington's disease in 1993. Diagnostic genetic testing is now available. This trial confirmed that the defective gene of Huntingtin is the cause of the symptoms of a patient suspected of Huntington's disease and confirmed the defects of people who are not at risk of developing symptoms but are at risk for parents of Huntington's disease Can be detected.
