What is Anxiety Disorder?

Anxiety disorder is a mental health condition characterized by excessive fear or worry that interferes with daily activities. According to the American Psychiatric Association, anxiety disorders are among the most common mental health issues, affecting millions of people worldwide. These disorders can manifest as intense, persistent, and often irrational fears that disrupt normal functioning.

Common Symptoms of Anxiety

The symptoms of anxiety can vary widely but commonly include:

• Restlessness: Feeling on edge or unable to relax.
• Increased Heart Rate: Experiencing palpitations or a racing heart.
• Sweating: Excessive perspiration even in non-stressful situations.
• Trembling: Involuntary shaking or trembling.
• Difficulty Concentrating: Struggling to focus on tasks or conversations.
• Fatigue: Feeling tired even without physical exertion.
• Irritability: Becoming easily annoyed or frustrated.
• Muscle Tension: Persistent tightness or pain in muscles.
• Sleep Disturbances: Trouble falling asleep or staying asleep, leading to insomnia.

These symptoms can vary in intensity and duration, often worsening during stressful situations.

Types of Anxiety Disorders

Anxiety disorders encompass several specific conditions, each with unique characteristics:

• Generalized Anxiety Disorder (GAD): This disorder involves chronic, exaggerated worry and tension, even when there is little or nothing to provoke it. The National Institute of Mental Health (NIMH) notes that individuals with GAD often anticipate disaster and may be overly concerned about health, money, family, or work.
• Panic Disorder: Characterized by recurrent, unexpected panic attacks—sudden periods of intense fear that may include palpitations, chest pain, shortness of breath, dizziness, or abdominal distress. The Anxiety and Depression Association of America (ADAA) highlights that these attacks can occur without warning and lead to persistent concern about having another attack.
