Anxiety disorders often occur along with other mental disorders, in particular depression, which may occur in as many as 60% of people with anxiety disorders. The fact that there is considerable overlap between symptoms of anxiety and depression, and that the same environmental triggers can provoke symptoms in either condition, may help to explain this high rate of comorbidity. Often times this comorbidity between these two disorders leads to higher suicide attempt rates, which adds more emotional and financial burden to the sufferers and their families.
