Anxiety Disorders are one of the most common psychiatric conditions. It is estimated that between 10 and 20 percent of the American people aged 18 and older suffer from some sort of Anxiety Disorder. That’s 30 to 60 million people!
The Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) of the American Psychiatric Association classifies nearly a dozen different Anxiety Disorders, from Acute Stress Disorder to Obsessive-Compulsive Disorder to Panic Attack to Post-Traumatic Stress Disorder.
New research from the University of Illinois groups these dozen disorders into two different types based on brain activities:
- Anxious apprehension (verbal rumination and worry)
- Anxious arousal (intense fear, panic, or both)
These two kinds of Anxiety may occur alone or in combination, with potentially important implications for treatment. Previous studies and treatment have not always differentiated between these two types.
