Anxiety is a common emotion that everyone experiences at some point in their lives. It is a natural response to stress or danger and is often characterized by feelings of apprehension, uneasiness, and fear. However, when anxiety becomes excessive and persistent, it can be considered a disorder.
Anxiety disorders are the most common mental health disorders in the United States, affecting over 40 million adults. They are characterized by excessive and persistent worry, fear, or nervousness that can interfere with daily life. Some of the most common anxiety disorders include generalized anxiety disorder (GAD), panic disorder, social anxiety disorder (SAD), and specific phobias.
Anxiety can be caused by a variety of factors, including genetics, brain chemistry, personality, and life experiences. People who have a family history of anxiety or who have experienced trauma, abuse, or stressful life events are more likely to develop an anxiety disorder.
The brain of an over anxious person can look different from that of a non-anxious person. Studies have shown that people with anxiety disorders have an overactive amygdala, which is the part of the brain responsible for processing fear and threat. The amygdala sends signals to the hypothalamus, which activates the fight or flight response, causing physical symptoms such as sweating, increased heart rate, and rapid breathing.
In addition to an overactive amygdala, people with anxiety disorders may also have imbalances in their neurotransmitters, which are chemicals that help the brain communicate with the body. Specifically, they may have low levels of serotonin, which is associated with feelings of well-being and happiness, and high levels of norepinephrine, which is associated with the fight or flight response.
Anxiety can also have physical symptoms, such as muscle tension, headaches, and gastrointestinal problems. These symptoms can be caused by the body’s response to stress, which can cause changes in the immune, digestive, and cardiovascular systems.
Fortunately, there are many effective treatments for anxiety disorders. Therapy, medication, and lifestyle changes, such as exercise and stress management techniques, can all help reduce anxiety and improve quality of life.
In conclusion, anxiety is a normal and natural response to stress or danger, but when it becomes excessive and persistent, it can interfere with daily life. An over anxious brain is characterized by an overactive amygdala and imbalances in neurotransmitters. Treatment options are available to help manage anxiety and improve overall well-being.
