Anxiety Disorders: Types, Symptoms, and Effective Treatments

Anxiety disorders are a group of mental health conditions characterized by excessive fear, worry, and physical symptoms that interfere with daily life. They are among the most common mental health disorders, affecting millions worldwide.

What are Anxiety Disorders?

Anxiety disorders involve persistent and intense feelings of fear or apprehension that go beyond normal, temporary worry or nervousness. They can affect how a person thinks, feels, and behaves and often include physical symptoms. While occasional anxiety is a normal response to stress, anxiety disorders are chronic and require professional intervention.

• Overactivity in the amygdala, the brain region that processes fear.

• Stressful life events, such as abuse, trauma, or significant life changes.
• Chronic stress due to work, finances, or relationships.

4. Medical Conditions

• Thyroid disorders, heart conditions, or chronic illnesses can contribute to anxiety symptoms.
