Mental health problems are common and knowing someone with one is even more common. However, it can be difficult to recognize a mental health problem in a friend, family member, or colleague, and know what to do if they are unwell. Common mental health problems include depression, anxiety disorders (such as panic disorder or social phobia), and substance abuse or dependence.
Anxiety can be defined as emotions which are typically negative in nature. It will often consist of fear and worry, and some organisms may even experience physical signs such as nausea or chest pains. Anxiety is a complex emotion, and is composed of a number of different elments. Some of these elements are somatic or cognitive, and the body will prepare itself to deal with an external threat. The heart rate speeds up, and the blood pressure is increased. The various muscles in the body will also receive elevated levels of blood. At the same time, the functions of the digestive system will slow down.
People who have anxiety will generally have a sense of dread. A number of voluntary and involuntary processes will take place in the body, and the goal of these processes is to get the organism away from the source that is causing it to have anxiety. Anxiety is an important emotion, and is designed to increase the survival rate of organisms. In humans it appears that anxiety comes from the hippocampus and amygdala, two regions of the brain. When a person senses bad odors or tastes, there will be a large amount of blood flow which will be present in the amygdala. The evidence also shows that medium levels of anxiety will be present in this situation as well.

Almost two percent of adult Americans, or three million people, will have panic disorder at some time in their lives. Panic disorder is a serious health problem and is very different from other types of anxiety.
