Panic disorder vs generalised anxiety disorder: attacks, worry and nursing care

Time course is the clearest difference

Panic attacks are discrete episodes. They start suddenly, usually peak within ten to twenty minutes, and include intense physical symptoms such as palpitations, chest discomfort, breathlessness, trembling and sweating, with fear of dying or losing control. Between attacks the person may feel relatively well, although many develop fear of the next attack.

GAD is continuous rather than episodic. The person worries excessively about several areas, such as work, money, health and family, more days than not for at least six months, and finds the worry hard to switch off. Physical features are lower grade but persistent: restlessness, muscle tension, fatigue, irritability, difficulty concentrating and disturbed sleep.

What panic disorder adds beyond having a panic attack

A single panic attack does not equal panic disorder. Panic attacks can occur in many anxiety, mood and medical conditions. Panic disorder requires recurrent unexpected attacks plus at least a month of persistent worry about more attacks or their consequences, or a change in behaviour, such as avoiding places where escape seems difficult.

People with GAD can also experience panic attacks, and the two disorders often coexist. So the presence of an attack in a stem does not by itself exclude GAD. Ask whether the core problem is fear of the attacks themselves or broad, ongoing worry about everyday life.

Avoidance can spread. Someone with panic disorder may stop driving, shopping or travelling alone in case an attack happens where help is far away. Ask what the client now avoids, because shrinking daily activity is a useful measure of severity and a target for exposure-based therapy.

Rule out physical causes before labelling anxiety

Panic symptoms can mimic a heart attack, and many people first present to emergency departments. In a nursing scenario with chest pain, breathlessness or palpitations, the nurse assesses vital signs and follows the chest pain or respiratory pathway rather than assuming a psychiatric cause, particularly in a client without an established diagnosis.

The same principle applies to GAD. Thyroid disease, stimulant or caffeine use, and substance withdrawal can produce anxiety and restlessness. A known anxiety diagnosis does not explain every new physical complaint, so new or changed symptoms still need assessment and reporting.

Nursing care during an attack versus ongoing GAD support

During a panic attack, stay with the client, keep the environment quiet, speak in short calm sentences and guide slow breathing. The person cannot process complex teaching at this level of anxiety, so explanations and problem-solving wait until the attack passes. Give prescribed as-needed medicine according to the order and reassess.

Care in GAD is longer term. Help the client recognise worry patterns, practise relaxation, keep regular sleep, reduce caffeine and alcohol, and engage with cognitive behavioural therapy. Teach that prescribed SSRIs or SNRIs take several weeks to work and that benzodiazepines, if used, carry a dependence risk and are reviewed regularly by the prescriber.

Worked scenario: choosing the right first response

A hypothetical client with diagnosed panic disorder suddenly reports a pounding heart, tingling hands and fear she is dying. Vital signs are stable apart from mild tachycardia. Options are teaching her about cognitive restructuring, leaving her alone to calm down, or staying with her and coaching slow breathing. Staying and coaching breathing is best; teaching waits until anxiety falls.

If the stem instead describes a client who has worried for months about finances and her children's safety and cannot sleep, an acute crisis response is not needed. The priority is assessment of worry, function and sleep, then supporting the therapy plan. Exam logic rewards matching the intervention to the anxiety level present.

A third variation tests safety. If the client with GAD mentions that she has started using alcohol every evening to quiet her worries, that becomes an assessment priority because it can worsen anxiety, interact with prescribed medicines and raise risk. Address it directly and report it to the treatment team.
