Anxiety attacks are also called panic attacks and refer to short-term feelings of intense fear and panic. People who have anxiety attacks may only have one during a lifetime, or may experience the attacks with regularity, depending on the cause of the attack. Although some anxiety attacks come without warning, most are triggered by an event or experience.
Heredity
A family history of depression, anxiety and other mental health disorders can be passed on through genetics.
Hormonal Issues
Anxiety attacks may be a result of changes in hormones that cause chemical imbalances in the brain after pregnancy or during menopause.
Daily Stress
Worries over problems at work, family issues or finances can compound over time to cause anxiety attacks.
Mental Disorders
According to the Mayo Clinic, anxiety attacks may be complications of depression and generalized anxiety disorder.
PTSD
Post-Traumatic Stress Disorder (PTSD) can result after witnessing or being in the middle of a traumatic experience, such as an auto accident, sexual assault, a terrorist attack or military duty, and can cause anxiety attacks.
OCD
Obsessive Compulsive Disorder (OCD) may be a reason for having anxiety attacks, especially if the affected person is prevented from carrying out his ritualistic behaviors.
Phobias
Exposure to a trigger of phobias, such as spiders, heights and airplane flights, can be a reason for anxiety attacks.
