Tip one: Panic attacks are all in your head. The reason why you have these attacks is probably unknown. One thing most doctors will agree on is that panic attacks are all in the victims head. Whether this is caused by a chemical imbalance, or not, the trigger for an attack has to come from the sufferer. If you are someone who suffers from these kinds of attacks, it is important to know as much as you can about them as to help control them. Causes of Anxiety Attacks The cause of an anxiety attack can vary from person to person. They may be caused by an upsetting event in someone's life or a fear of something they have experienced growing up. There are some signs or “red flags” to consider when determining if you are a candidate for a mental health professional that include: feeling unable to work, feeling unable to keep your normal behavior patterns or appearance or hygiene patterns, cutting off social connections, trouble sleeping, trouble eating, and trouble bathing. An anxiety attack, conversely, is an unexpected episode that usually involves fear as oppose to an overwhelming feeling. A sign of anxiety attack can be anything from irregular heartbeats to chest pain. They also include: shaking, twitching, trembling, hot flashes, chills, “rubber legs”, tingling in extremities, difficulty sleeping, unpredictable sleeping patterns, body tension, aches and pains, sweating, clamminess, and stomach problems such as nausea or “butterflies”. Patients discuss shaking, trembling, chills, numbness in extremities, heart palpitations, and trouble breathing among other things that are caused by the great difficulty of a panic attack. Anxiety attack heart problems are common because of the close association stress has with other heart problems. In today’s world anxiety disorders are the most common mental illness. In the United States alone 40 million (18.1%) of the adult population is affected. These numbers are on the increase all over the world, demanding immediate attention. Even though studies are usually made only on adults (over 18 years old), this disorder affects all age groups.
