There appears to be some genetic component in panic disorder. However, those with no family history of this disorder may develop.
The events distressing or contact with an element related to a phobia may contribute to the onset of a panic attack. This can also occur following an episode of depression, thoughts too repetitive, intense feelings of insecurity, events that become too heavy to carry.
The panic attacks can also accompany a physiological functioning of the heart, mitral valve prolapse.
We do not know completely the exact cause of panic disorder. However, research suggests that panic disorder may be caused by imbalances of certain chemicals in the brain. panic disorder also tends to be hereditary, and the presence of an important genetic factor is likely. Too much stress and a history of trauma are also factors that may be associated with the onset of panic disorder.
Panic disorder can also be caused by certain conditions such as overactive thyroid gland (called hyperthyroidism) and some disorders of the heart.
Some the phenomena triggers for panic attack include:
alcohol in large quantities;
excessive consumption of caffeine (eg. coffee, tea, cola);
taking stimulants or cocaine;
taking or suddenly stopping of some drugs sold on ordo.
