Other compelling, if controversial, research has long pursued an entirely different cause of OCD: streptococcal infection. As long ago as the 17th century, British physician Thomas Sydenham first noticed a link between childhood strep and the later onset of a tic condition that became known as Sydenham's chorea. Modern researchers who saw a link between tics and OCD began wondering if, in some cases, strep might be involved with both...
Huntington's disease, formerly known as Huntington's chorea for the involuntary "dancelike" movements which characterize sufferers, kills brain cells and leads to a variety of both motor and mental symptoms, according to Alice R. Wexler, a supporter of the Hereditary Disease Foundation...
...serious genetic diseases at the fetal stage, which will lead some parents to opt for abortion. But there will also be preventive measures for people who want to avoid passing their defective genes on to their children. When one parent carries the deadly and dominant gene for Huntington's chorea, for example, there is a 50% chance that any offspring will have it too. To reduce those odds to zero, doctors of the future will extract several eggs from the prospective mother and fertilize them in a test tube with her husband's sperm. When the fertilized eggs have grown...
...have repaired some spinal-cord injuries, allowing injured rats to run at normal speed. Implants in the brain have improved memory and learning. The work has led scientists to speculate that the cells can be used to treat epilepsy, combat leukemia and stop such degenerative diseases as Huntington's chorea and Alzheimer...
Cystic fibrosis, cleft palate, muscular dystrophy, Alzheimer's disease, Huntington's chorea. The list of disorders that have been traced to a specific gene or gene region seems to grow on a weekly basis. The latest in this gene- of-the-week series: the discovery of a region on the X chromosome that is linked to manic depression, a mental disorder that affects as many as 2 million Americans. The finding, published in Nature by an American and Israeli research team, was based on studies of five families in Jerusalem. It marks the second time in three weeks that...
