| [00:02.75] | this is the Health Report. |
| [00:04.99] | An international team of researchers |
| [00:07.93] | has developed a drug that could help |
| [00:10.87] | in the treatment of post-traumatic stress disorder. |
| [00:14.50] | PTSD is a mental condition that can develop |
| [00:18.89] | when someone seize a disturbing event, or serious of events. |
| [00:24.71] | People who suffer from it experience increased anxiety, |
| [00:29.55] | depression and may have problems with their memory. |
| [00:33.78] | Scientists say the drug could be given to someone |
| [00:37.67] | immediately following a trauma to prevent the development of PTSD. |
| [00:43.79] | Raul Andero Gali is a researcher |
| [00:47.27] | at Emory University in Atlanta, Georgia, |
| [00:50.47] | who studies the biology of PTSD. |
| [00:53.65] | He says it is the only mental disorder |
| [00:57.19] | that has a known trigger or cause, |
| [00:59.92] | such as a car accident, or being in armed conflict. |
| [01:05.45] | And this means researchers have a better chance of |
| [01:09.04] | finding a treatment for it. |
| [01:11.18] | "So we can even define more clearly |
| [01:13.47]which is the stimulus or the stressor that trigger[s] | the disease, |
| [01:18.75] | whereas with other psychiatric diseases it is way more difficult. |
| [01:23.23] | For example, with depression or schizophrenia |
| [01:25.18] | it is more uncertain what is triggering that disease." |
| [01:30.23] | Doctor Gali and other researchers at Emory, |
| [01:33.57] | the University of Miami in Florida, |
| [01:36.25] | Scripps Research Institute in Florida |
| [01:39.15] | and the Max Planck Institute of Psychiatry in Munich, Germany |
| [01:44.28] | worked to find gene associated with the development of PTSD. |
| [01:49.96] | They found that in some people experiencing a high degree of stress, |
| [01:55.68] | a gene called OPRL1 releases a protein receptor |
| [02:02.05] | for a molecule called nociceptin in the brain. |
| [02:06.33] | Doctor Gali says when that happens, |
| [02:10.89] | people experience symptoms of post-traumatic stress disorder. |
| [02:15.12] | The researchers experiment it on mice |
| [02:18.40] | to develop a drug that blocks the receptor, |
| [02:21.95] | reducing symptoms of anxiety and fear. |
| [02:26.00] | Doctor Gali says investigators tested their drug, called SR8993, |
| [02:33.26] | in mice train to feel an electric shock |
| [02:37.15] | whenever they heard a specific sound. |
| [02:40.19] | The mice became very stressed when they heard the sound. |
| [02:44.82] | Doctor Gali says immediately after the sound and shocks, |
| [02:50.19] | some of the mice were given SR8993, |
| [02:54.78] | others were given a drug with no active ingredient called a placebo. |
| [03:01.08] | "The day after the animals were tested to see |
| [03:04.42] | how afraid they were for the tone. |
| [03:06.76] | And the animals that got the compound SR8993 |
| [03:11.59] | presented less fear to the tone. |
| [03:14.38] | So their conservation of fear memories is decreased." |
| [03:20.16] | Doctor Gali says much work needs to be done |
| [03:23.59] | to determine if SR8993 is effective in humans. |
| [03:29.27] | If it is, he believes it could be given to, for example, |
| [03:34.20] | soldiers returning home from a war zone |
| [03:37.99] | to keep them from developing PTSD. |
| [03:41.59] | An article on this possible treatment |
| [03:45.16] | for post-traumatic stress disorder is published |
| [03:48.60] | in the journal Science Translational Medicine. |
| [03:52.08] | And that's the Health Report, |
