Anxiety disorder can cause excessive worry and nervousness, often for no apparent reason. There are several types of anxiety disorders including generalized anxiety disorder, panic disorder, obsessive-compulsive behavior, phobia and post-traumatic stress disorders, according to the University of Maryland Medical Center. Therapeutic treatment and medication usually work to relieve the symptoms.
Chronic Worry
The emotional symptoms of anxiety disorder can result in exaggerated concerns and tension, the Substance Abuse and Mental Health Services Administration points out. Generalized anxiety disorder is characterized by chronic worry. These extreme emotional reactions can also lead to physical symptoms such as sweating, trembling or headaches. Restlessness and insomnia can also result as well.
Panic and Fear
Panic disorder may strike a person for no reason, leading to a racing heartbeat and shortness of breath as fear grows increasingly intense. The obsessive feelings may eventually cause an upset stomach, chest pains or feelings of choking. A full-blown panic attack could develop in which the person is overwhelmed by fears that make it difficult to function. Many people who have these attacks are constantly worried about having future attacks, compounding the problem.
Obsessive Thoughts
This form of anxiety disorder often occurs with obsessive-compulsive disorder. Sufferers have recurrent unwanted thoughts or obsessions. Sometimes the thoughts can result in ritualized behavior such as washing hands often because of fears of germs or dirt. Symptoms may also include repeatedly checking to make sure doors are locked or lights are off in the home.
Flashbacks
People who suffer from post-traumatic stress disorders may have anxiety attacks when they experience memories or encounter reminders of past traumatic experiences. Persistent anxiety can cause sufferers to avoid places or situations that bring back uncomfortable memories. Symptoms can also lead to panic attacks. Violent acts or traumatic disasters can cause some people to develop this anxiety disorder.
Avoiding Social Situations
Social anxiety can develop in someone who has a social phobia that leads to extreme self-consciousness around people. People with these symptoms often have feelings of uneasiness and a fear of interacting with people during normal events. They may have phobias that range from a fear of public speaking to fears of being in a situation where there seems to be no escape. Mental confusion when interacting with people may also be a sign of social anxiety or fear of being involved in social situations.
