What Research is being done.?
Basic neurobiology.-Now that the HD gene has been located, investigators in the field of neurobiology-which encompasses the anatomy, physiology, and biochemistry of the nervous system-are continuing to study the HD gene with an eye toward understanding how it causes disease in the human body.
Clinical research.- Neurologists, psychologists, psychiatrists, and other investigators are improving our understanding of the symptoms and progression of the disease in patients while attempting to develop new therapeutics.
Imaging.- Scientific investigations use technology that will enable scientists to see what the defective gene does to various structures in the brain and how it affects the body's chemistry and metabolism.
Animal models.- Laboratory animals, such as mice, are being bred in the hope of duplicating the clinical features of HD and can soon be expected to help scientists learn more about the symptoms and progression of the disease.
Fetal tissue research.- Investigators are implanting fetal tissue in rodents and nonhuman primates with the hope that success in this area will lead to understanding, restoring, or replacing functions typically lost by neuronal degeneration in individuals with HD.

How can I prevent this from happening to me.?
Unfortunately, this disease cannot be prevented. It is inherited. Even though genetic counseling is advised if there is a family history of this disease.
How can this disease be treated and or cured if I have it.?
Unfortunately, there is no cure nor treatment for this disease. Nor is there a way to stop the disease from getting worse. Although, dopamine blockers (hormones produced by the adernal glands which are located on top of the kidneys and are released into the blood in times of emotional or physical stress) are distributed to help reduce abnormal behaviors and movements. And other drugs are used to try to control extra movements. The only thing to do for a person with huntington's disease is to try to make them as comfortable as possible. Some evidence have proved that the co-enzyme Q10 can be used to help slow down the disease.
NOTE: Depression and suicide are common among people with this disease.!

How would the doctor know I have the disease.?
Your doctor will perform a physical exam while he/she checks to see if you have either: abnormal movements, abnormal reflexes, a "prancing" and wide walk, hesistant speech and problems enunciating your words. The doctor might even perfom a head CT scan which will show whether you have a loss of brain tissue. You may get asked about your family's health history and symptoms. The doctor will also have the tools to tell you whether you carry the gene for Huntington's Disease.
How is Huntington's Disease caused.?
Well, Huntington's Disease is caused by a genetic defect in chromosome #4. The disease causes a part of the DNA (the CAG repeat) to occur more than the average 10 to 35 times. In someone who has this disease, the CAG repeat occurs about 36 to 120 times. As the gene is passed from generation to generation, the number of repeats tend to get larger. The larger the number of repeats, the greater the chances of you developing the disease at an early age. So, as the disease is passed through the family, it becomes more evident at an early age.
What are some symptons that I should look for.?
Some symptoms you should look for are hallucinations, irritability, moodiness, restlessness, fidgeting, and paranoia. Some abnormal and unusual movements include: head turning to shift eye position, facial movements (including grimaces), slow, uncontrolled movements, quick, sudden, sometimes wild jerking movements of the arms, legs, face, and other body parts, and unsteady gait. Also, you should pay attention if you or a friend have loss of memory, loss of judgment, speech changes, personality changes, disorientation and confusion.
If you are experiencing anxiety, stress, tension, difficulty swallowing, speech impairments, rigidity, slow movements and/or tremors, you may want to get checked out.

When did people find out about Huntington's Disease.?
American doctor George Huntington first described the disorder in 1872. He wrote a book called "On Chorea and the word "chorea" comes from the Latin and Greek words meaning chorus or a group of dances. The term was given to the "dancing disorders" that became noticed in the Middle Ages. In those days, people with chorea, like the involuntary muscle jerks and twitches characteristic of Huntington's Disease were often thought to be possessed by devils. It is believed that at least one of the alleged "witches" executed in Salem, Massachusetts in the 1690's had this disease. Before, this disease was hard to figure out because people lived short lives, but now, the symptoms show up because we live longer.
What exactly is Huntington's Disease.?
Huntington's disease is a disorder passed down through families in which certain nerve cells in the brain waste away, or degenerate. this disease causes disabilites that get worse over time. People usually die within 15 to 20 years after being diagnosed. Cause of death is usually infection or suicide. Individuals with Huntington’s Disease have one dominant Huntington’s allele and one normal allele. It is unusual for a person to inherit two dominant Huntington’s alleles because this would mean both that person’s parents have Huntington’s. There is a 50% chance that a parent with Huntington’s will pass the gene on to his or her children. This disease is found on chromosome 4 and it is autosomal dominant.
