The Makings of an Anxious Temperament

In children, an anxious temperament can be a warning sign. Kids who are painfully shy and nervous are more prone to anxiety disorders and depression later in life, and they're more likely to self-medicate with alcohol and other drugs. But what causes a child to have an anxious temperament in the first place? A new study with monkeys finds that an anxious temperament is partly heritable and that it's tied to a particular brain region involved in emotion. via The Makings of an Anxious Temperament - ScienceNOW.
