; it is likely that many factors contribute to a person's chances of developing anxiety. Scientists have broken down the potential causes into three groups, genetics and early learning, brain biochemistry, and the fight or flight mechanism.

Brain Biochemistry - Chemical Imbalance
Neurotransmitters are chemical messengers in the brain that regulate a person's thoughts and feelings. Two of the primary neurotransmitters that affect a person's feelings are serotonin and dopamine. When there is an imbalance of these chemicals, a person can feel depressed or anxious.

Genetics and Early Learning
Growing up in a family where fear and anxiety are constantly shown to children by role models can "teach" them to be anxious as well. In addition, if a child grows up in an abusive home, he or she may learn to always expect the worse. Research also shows a genetic predisposition for a chemical imbalance in people with anxiety.
Changing the way we think can mean attempting to undo years of thought patterns. Some of these thought patterns may be negative and automatic.

Fight or Flight Mechanism
When a person senses danger. The body's fight or flight mechanism causes the heart rate to increase, the eyes to dilate, and the body to prepare itself for a dangerous situation. These responses allow a person to protect him/herself. Even though these effects are intended to be a good thing, sometimes the body misunderstands a situation and believes that there is danger when in reality there is not (taking a test, giving a speech, etc).
