Panic disorder is an anxiety disorder characterised by sudden, severe panic attacks. The unexpected and uncontrollable occurrence of panic attacks can seriously affect a person's normal daily life. Panic disorder is also defined by features such as efforts to prevent future attacks and the development of avoidance behaviours after the first panic attack. Important points include:

Panic attacks: Panic disorder is characterised by recurring panic attacks — brief (usually 10–20 minutes) episodes of sudden, intense fear, anxiety, or panic accompanied by physical symptoms.
Physical symptoms: During panic attacks, people often experience shortness of breath, palpitations, trembling, sweating, nausea, dizziness, and a feeling of fainting.
Avoidance behaviours: Avoidance of panic attacks is a strategy the person may adopt. These behaviours can limit social interaction, going to crowded places, or facing certain situations.
Agoraphobia: A condition frequently seen alongside panic disorder, defined as avoidance of places or situations where panic attacks have occurred.
Treatment: Cognitive behavioural therapy (CBT) and medication can be used to treat panic disorder. CBT is an effective form of therapy focused on changing thoughts and behaviours. Antidepressants and anxiolytics may also be used.
Support and mindfulness: Support groups and mindfulness techniques can help people with panic disorder cope with stress and manage panic attacks more effectively.

The treatment process for panic disorder may vary depending on the individual's needs and symptoms. Professional help is important for developing an appropriate treatment plan and managing symptoms effectively.
