Risk factors

These factors may increase your risk of developing an anxiety disorder:

• Trauma. Children who endured abuse or trauma or witnessed traumatic events are at higher risk of developing an anxiety disorder at some point in life. Adults who experience a traumatic event also can develop anxiety disorders.
• Stress due to an illness. Having a health condition or serious illness can cause significant worry about issues such as your treatment and your future.
• Stress buildup. A big event or a buildup of smaller stressful life situations may trigger excessive anxiety — for example, a death in the family, work stress or ongoing worry about finances.
• Personality. People with certain personality types are more prone to anxiety disorders than others are.
• Other mental health disorders. People with other mental health disorders, such as depression, often also have an anxiety disorder.
• Having blood relatives with an anxiety disorder. Anxiety disorders can run in families.
• Drugs or alcohol. Drug or alcohol use or misuse or withdrawal can cause or worsen anxiety.
