Improve The Treatment Of PTSD Can Be Through The Amygdala.
Researchers who have planned a mistress with a missing amygdala - the part of the brain believed to procreate fear - report that their findings may help improve treatment for post-traumatic highlight disorder (PTSD) and other anxiety disorders. In perhaps the first human study confirming that the almond-shaped building is crucial for triggering fear, researchers at the University of Iowa monitored a 44-year-old woman's reply to typically frightening stimuli such as snakes, spiders, horror films and a haunted house, and asked about traumatizing experiences in her past totkey. The woman, identified as SM, does not seem to be afraid a wide range of stimuli that would normally frighten most people.

Scientists have been studying her for the past 20 years, and their old research had already determined that the woman cannot recognize fear in others' facial expressions. SM suffers from an very rare disease that destroyed her amygdala. Future observations will determine if her persuade affects anxiety levels for everyday stressors such as finance or health issues, said bookwork author Justin Feinstein, a University of Iowa doctoral student studying clinical neuropsychology. "Certainly, when it comes to fear, she's missing it lanja sleeping sex. She's so solitary in her presentation".

Researchers said the study, reported in the Dec 16, 2010 emanation of the journal Current Biology, could outstrip to new treatment strategies for PTSD and anxiety disorders. According to the US National Institute of Mental Health, more than 7,7 million Americans are moved by the condition, and a 2008 analysis predicted that 300000 soldiers returning from fighting in the Middle East would experience PTSD. "Because of her perspicacity damage, the patient appears to be immune to PTSD," Feinstein said, noting that she is otherwise cognitively regular and experiences other emotions such as happiness and sadness.

In addition to recording her responses to spiders, snakes and other horrifying stimuli, the researchers measured her experience of fear using many standardized questionnaires that probed various aspects of the emotion, such as cowardice of death or fear of public speaking. She also carried a computerized emotion engagement book for three months that randomly asked her to rate her fear level throughout the day.
