Panic Disorder

Panic disorder is a chronic anxiety condition characterized by recurrent, unexpected panic attacks—abrupt surges of intense fear or discomfort accompanied by physical and cognitive symptoms. It involves persistent worry about future attacks or maladaptive behavioral changes to avoid them.

Etiology is multifactorial, involving a combination of genetic vulnerability, neurotransmitter dysregulation (serotonin, norepinephrine, GABA), and environmental stressors. Psychological factors include high neuroticism and early childhood trauma.

Pathophysiology involves overactivity of the "fear network" in the brain, centered on the amygdala, hypothalamus, and brainstem. Dysregulation of the autonomic nervous system leads to the "fight-or-flight" response. Chronic hyperventilation may exacerbate symptoms via hypocapnia-induced cerebral vasoconstriction.

Global lifetime prevalence is approximately 2–3%. Onset typically occurs in late adolescence or early adulthood. It is twice as common in females as in males.

Family history, major life transitions, smoking, history of childhood physical or sexual abuse, and high baseline anxiety or sensitivity to bodily sensations.

A. Early Symptoms: Palpitations, trembling, lightheadedness.
B. Common Symptoms: Tachycardia, dyspnea, chest pain, nausea, diaphoresis, fear of dying or losing control.
C. Advanced Symptoms: Agoraphobia, avoidance behaviors, anticipatory anxiety.
D. Emergency Symptoms: Severe unrelenting chest pain, loss of consciousness, suicidal ideation.

Usually normal. During an attack: tachycardia, tachypnea, diaphoresis, tremors, and elevated blood pressure.

A. Clinical Assessment: DSM-5 criteria (recurrent, unexpected attacks + 1 month of persistent worry/maladaptive behavior).
B. Laboratory Testing: Rule out organic causes (hyperthyroidism, pheochromocytoma).
C. Imaging Studies: Generally unnecessary; used only if neuro-pathology is suspected.
D. Functional Tests: Not applicable.
E. Biopsy Findings: None.
F. Genetic Testing: Not clinically indicated.
G. Differential Diagnosis: Cardiac arrhythmia, asthma, hypoglycemia, substance withdrawal.

Test Name: Thyroid Stimulating Hormone (TSH)
Type: Blood Test
Purpose: Exclude hyperthyroidism
Expected Findings: Normal range
Interpretation: High TSH indicates hypothyroidism; low TSH suggests hyperthyroidism.

Purpose: ECG and Holter monitoring are essential to rule out cardiac arrhythmias mimicking panic attacks. Brain MRI is ordered only if neurological deficits are present.

Generalized Anxiety Disorder (GAD), Social Anxiety Disorder, Pulmonary Embolism, Myocardial Infarction, Hyperthyroidism, Pheochromocytoma.

Depression, substance abuse, agoraphobia, work/social impairment, financial hardship.

A. Lifestyle Modifications: Regular exercise, caffeine restriction, sleep hygiene.
B. Preventive Measures: Stress reduction, CBT.
C. Medical Treatment: SSRIs/SNRIs (First-line), Benzodiazepines (Short-term/Emergency).
D. Surgical Treatment: None.
E. Interventional Procedures: Vagus Nerve Stimulation (experimental).
F. Rehabilitation: CBT/Psychotherapy.
G. Emergency Management: Calming techniques, short-acting benzodiazepines if necessary.

Good with treatment; most patients show significant improvement with CBT and medication. Relapse is possible if treatment is discontinued prematurely.

Early intervention in childhood anxiety, psychoeducation, and avoiding substance abuse.
