Types of Anxiety Disorders

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and leading health sources, the most common anxiety disorders include:

1. Generalized Anxiety Disorder (GAD)

Characterised by persistent and excessive worry about everyday matters lasting for months or years. Symptoms include restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbances. People with GAD often find it hard to control their worry even when there is little or no reason for concern.

2. Panic Disorder

Involves recurrent and unexpected panic attacks — sudden episodes of intense fear or discomfort. Physical symptoms include a rapid heartbeat, chest pain, shortness of breath, dizziness, sweating, chills, and numbness. During attacks, individuals may feel detached from reality or fear losing control, often worrying about having another attack.

3. Phobia-Related Disorders

These include intense, irrational fears of specific objects or situations, such as heights, flying, animals, or enclosed spaces (claustrophobia). Agoraphobia, the fear of being in places where escape might be difficult, is also common. People with phobias typically go to great lengths to avoid triggers, which can severely limit their activities.

4. Social Anxiety Disorder

Characterised by an intense fear of social situations where one might be judged, embarrassed, or scrutinised. This fear can disrupt work, school, and social interactions. Symptoms include blushing, trembling, nausea, difficulty speaking, and avoidance of social events.

5. Other Anxiety Disorders

These include separation anxiety disorder, selective mutism, and anxiety due to medical conditions or substance use. While obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD) share anxiety features, they are classified separately.

Symptoms of Anxiety Disorders

Symptoms vary depending on the type of anxiety disorder but generally include:

• Psychological Symptoms: Excessive worry, fear, irritability, restlessness, difficulty concentrating, and feelings of dread or impending doom.
• Physical Symptoms: Rapid heartbeat, sweating, trembling, dizziness, muscle tension, headaches, stomach upset, and fatigue.

Causes and Risk Factors

The exact causes of anxiety disorders are not fully understood. Experts believe a combination of genetic, environmental, psychological, and developmental factors contribute. Stressful life events, trauma, brain chemistry imbalances, and family history can increase risk.

Treatment Options

Anxiety disorders are treatable, and many people improve significantly with proper care. Common treatments include:

• Psychotherapy: Cognitive Behavioral Therapy (CBT) is the most effective form, helping individuals identify and change negative thought patterns and behaviours. Exposure therapy is used for phobias by gradually facing feared situations.
• Medications: Antidepressants (like SSRIs), benzodiazepines, and beta-blockers may be prescribed to manage symptoms. Medication is often combined with therapy.
• Lifestyle Changes: Regular exercise, mindfulness, relaxation techniques, and adequate sleep support overall mental health.
• Support Groups: Connecting with others facing similar challenges can provide emotional support and coping strategies.
