Potential causes of developing PTSD – 1: War

The most traumatic experience that could happen to military personnel on duty is to see a loved one die. An incident such as this can have a greater impact on the mental well-being of a person than probably the psychosocial strain of getting injured oneself.

Post the Gulf war, a survey done by David Marlowe, an expert working in the Department of Defense, found that the death of a friend is more sickening and heart rendering than even one’s first kill. Interestingly, in the survey, maximum respondents revealed that the act of killing one’s enemy made him or her liable to be more distressed than facing injuries on one’s own self. Read more

Is there any association between anxiety and dementia?

However, the findings of a Swedish study conducted on twins confirms a definite association between anxiety and dementia.

Extended test timing does not help students with ADHD, finds study

Many medical experts advocate the need to provide test accommodations, such as extending test timing and offering frequent breaks, for the children affected by attention deficit hyperactivity disorder (ADHD).

According to a study, published in Learning Disabilities-A Multidisciplinary Journal, both extended testing time timing or frequent breaks did not help much the students with ADHD in performing better on a standardized test compared to others. One potential reason identified by the researchers could be that the ADHD-affected students lack the understanding of how to effectively utilize such accommodations. Read more

New anxiety medications in development – Part 3: BNC210

Of the few new and promising anxiety medications under development, BNC210, one of the anxiolytic medicines, has demonstrated a potent anxiolytic effect. Although the trials of this medication are still under way, it has shown efficacy in suppressing the malfunctioning areas of the brain that are responsible for anxiety.
