Scientists are investigating several medicines that could slow the progress of Huntington's disease. Some of these have shown promise and are being tested in clinical trials. Examples include an antibiotic medicine called minocycline and the nutritional supplement, coenzyme Q10.
Some clinical studies have used stem cells (the most basic form of cells from which others develop) to grow cells that can be transplanted into the brain of people with Huntington's disease to improve their outlook. However, research is still in the very early stages.

Scientists are also hopeful that research into RNA interference (RNAi), which can potentially shut off any gene in the body, may lead to an effective treatment in the future. This is really a horrible disease but at least there does some to be a glimmer of light at the end of the tunnel.

Emotional symptoms include depression, not only because of the burden of having a progressive disorder, but as a direct result of the damage to certain brain cells.

You are right! This diagnosis is a terrific burden for the sufferer or potential sufferer and that is why so much care is taken in screening people before they are told whether or not they have inherited this horrible condition. Added to that the effect the disease has on the brain and it is a very sad and bleak picture for many of those connected in any way to this disease.
