Health Research: In pursuit of precision medicine for PTSD ♦ Questionnaire beats blood test in identifying at-risk drinking ♦ Stopping malaria in its tracks

Stopping malaria in its tracks A new drug acts as a roadblock for malaria, curing mice of established infection, according to researchers. Treatment was not associated with obvious side effects, suggesting that the drug may also be safe and effective in human.
Keep fears at bay by learning something new Exposure therapy is a commonly used and effective treatment for anxiety disorders, including posttraumatic stress disorder, obsessive-compulsive disorder, and phobias. The goal of such therapy is to extinguish fear, which is accomplished by presenting cues that are known to predict a negative experience in the absence of that experience. Over time, learning that the 'danger cue' is no longer dangerous produces extinction of the fearful response. However, fears and the associated defensive behaviors resulting from that fear often return after they have been extinguished, undermining the long-term effectiveness of treatment
In pursuit of precision medicine for PTSD Brain scans of war veterans with posttraumatic stress disorder have led researchers to an area of the prefrontal cortex that appears to be a good predictor of response to treatment with SSRIs -- the first-line drug treatment for PTSD.
Questionnaire beats blood test in identifying at-risk drinking among ER patients Emergency room physicians treating patients with alcohol-related trauma can better identify those at risk of future drinking-related trauma with a 10-point questionnaire rather than the standard blood alcohol content test, according to a study.
Words jump-start vision,  A new study shows that words have a profound effect even on the first electrical twitches of perception.
