Anxiety Disorders — Study Material for BAMS Students | Ayurveda | Compilation.
What Is Anxiety?
Anxiety is a subjective sense of unease, dread or foreboding — an uncomfortable feeling of vague fear or apprehension accompanied by characteristic physical sensations. When anxiety becomes excessive, persistent, or disproportionate to any real danger, it crosses into disorder territory.
Anxiety disorders share features of excessive fear and related behavioural disturbances. Many develop during childhood and tend to persist without treatment.
Excessive or Persistent
Lasting beyond a developmentally appropriate period.
Out of Proportion
Response far exceeds what the situation warrants.
Impairs Functioning
Interferes with social, occupational, or important daily areas.
Overestimates Danger
Individuals consistently overestimate risk in situations.
Epidemiology
Anxiety disorders typically develop before age 30 and are more common among women, individuals with social challenges, and those with a family history of anxiety or depression.
Who Is Most at Risk?
Why Does Anxiety Develop?
Multiple converging theories explain the origins of anxiety disorders — from genetic roots to learned behaviour.
Biological / Genetic
First-degree relatives, twin studies, and family history all implicate hereditary factors. Increased sympathetic activity is noted neuroanatomically.
Psychoanalytic Theory
Freud: anxiety results when ego defence mechanisms fail to resolve the id–superego conflict. Failed repression leads to neurotic symptoms.
Cognitive Behaviour Theory
Anxiety stems from faulty cognitions — overestimating danger and underestimating one's own coping ability.
Behaviour Theory
Anxiety is a conditioned response to an environmental stimulus that generalises over time through social learning.
Psychosocial Factors
Disturbed attachment, childhood maltreatment, overprotective parenting, stressful life events, and adverse family environment.
What Happens in the Brain?
Three primary neurotransmitter systems are implicated in anxiety disorders.
GABA System
Reduced GABA receptor binding increases nerve-cell excitability. Benzodiazepine receptor reduction is seen in GAD (temporal lobe) and PTSD (cortical).
Serotonin (5-HT)
Abnormal regulation of serotonin release, reuptake, or receptor responsiveness plays a key role across multiple anxiety disorders.
Noradrenergic System
The locus coeruleus acts as an alarm centre — releasing norepinephrine in response to perceived threat, producing the anxiety experience.

Types of Anxiety Disorders
DSM-5 classifies the following disorders. Tap any row to expand details.
Childhood-onset disorder with excessive fear about separation from parents or attachment figures.
- Nightmares about separation
- Physical distress symptoms when separated
- Refusal to leave attachment figures
- Repeated temper tantrums
- Persistent worry about unexpected events causing separation
Failure to speak in certain social situations (e.g. school) despite speaking normally elsewhere.
- Excessive shyness and social isolation
- Fear of embarrassment; clinging to caregivers
- Temper tantrums; lack of social communication
- Interference with academic performance
Persistent, unrealistic fear of a specific object/situation beyond voluntary control, causing significant distress or impaired functioning.
- Natural environment — storms, water (Hydrophobia), trees (Dendrophobia)
- Animals — dogs (Cynophobia), frogs (Batrachophobia), horses (Equinophobia)
- Medical/Mutilation — needles (Trypanophobia), dentists (Dentophobia), blood (Hemophobia)
- Situational — enclosed spaces (Claustrophobia), heights (Aerophobia), public speaking (Glossophobia)
Fear of social situations where the person may be scrutinised, embarrassed, or judged negatively.
- Strong, persistent fear of interpersonal situations
- Fear of meeting unfamiliar people or public eating/drinking
- Fear of public speaking or performance
- Physical signs: sweating, blushing, rapid heartbeat, trembling, shortness of breath
Fear of places where rapid exit is impossible or help is unavailable — being trapped and helpless.
- Enclosed spaces (cinemas, elevators, stores)
- Open spaces (parking lots, bridges)
- Public transport (bus, train, aeroplane)
- Crowds or waiting in lines
Recurring, unexpected panic attacks — begin abruptly, peak within ~10 minutes, usually short-lived (<1 hour).
- Sweating, trembling, palpitations
- Shortness of breath, chest pain
- Sensation of choking or impending heart attack
- Fear of dying; altered sense of reality
Chronic, persistent, unrealistic worry interfering with daily activities. More common in women.
Diagnosis: anxiety/worry ≥ 6 months AND 3+ of — tension/restlessness, fatigue, difficulty concentrating, irritability, sleep difficulties.
Risk factors: family history, stress, emotional trauma, unemployment/poverty, drug abuse.
Develops after exposure to psychological trauma — natural disasters, war, assault, rape.
Nervousness or panic directly caused by use, abuse, or withdrawal of a substance or medication. Medical conditions such as hyperthyroidism, hypothyroidism, hyperparathyroidism, vitamin B12 deficiency, and pheochromocytoma can also trigger anxiety symptoms.
Chronic disorder with uncontrollable, recurring obsessions (thoughts/impulses) and compulsions (repetitive behaviours).
Common obsessions: contamination, need for symmetry, forbidden thoughts.
Common compulsions: cleaning, checking, ordering, counting, repeating.
Diagnosis: MRI/CT may show enlarged basal ganglia; PET shows increased glucose metabolism in basal ganglia.
How Are They Diagnosed?
A multi-pronged approach combining physical examination, structured questioning, validated questionnaires, and laboratory tests.
Physical Exam
Assess appearance, behaviour, and cooperation. Look for sweaty palms, restlessness, and whether anxiety links to an underlying medical condition.
Clinical Interview
Detailed questions about symptom intensity, duration, medical history, medications, family history, and daily-life interference.
Questionnaires
Validated tools such as the GAD-7 or Anxiety Screening Questionnaire-15 (ASQ-15) guide diagnosis.
Lab & Imaging Tests
Blood/urine tests, thyroid function, EEG, CT scan, ECG, and chest X-ray to rule out physical causes.
Managing Anxiety Disorders
Treatment is most effective when combining psychological therapies with lifestyle changes. Research shows CBT is more effective than medications long-term.
Psychoeducation
Understanding the "fight-or-flight" response gives patients control over symptoms.
Mindfulness
Guides attention back to the present, unhooking from anxiety-provoking thought spirals.
Correct Breathing
Diaphragmatic breathing counters hyperventilation — belly should move, not chest.
Relaxation Techniques
Progressive muscle relaxation, abdominal breathing, isometric relaxation exercises.
Cognitive Therapy (CBT)
Challenges faulty beliefs through rational self-talk, reality testing, and cognitive restructuring.
Exposure Therapy
Step-by-step confrontation of fears to desensitise. Start with the least threatening fear and work up.
Dietary Adjustments
Ensure adequate magnesium, vitamin B, and calcium. Avoid caffeine, nicotine, salt, and artificial additives.
Exercise
Burns stress chemicals and promotes relaxation. Aim for physical activity 3–4 times per week.
Assertiveness Training
Communicating needs honestly builds self-confidence and reduces anxiety-driven passivity.
Support Groups
Provide peer understanding, psychoeducation, and social network development.
Pharmacological Treatments
When needed, medications manage symptoms while psychotherapy takes effect. Always consult a qualified clinician.
SSRIs
SNRIs
TCAs
Benzodiazepines
Beta-Blockers

Chittodvega — The Ayurvedic View
Chittodvega (चित्तोद्वेग) — from Chitta (mind/consciousness) + Udvega (anxiety/agitation) — describes the anxious state of mind. Though not named separately in classical texts, it is described as a precursor to Unmada (psychosis).
Nidana (Causes)
Lakshana (Symptoms)
Chikitsa (Treatment) — Three Pillars
Daivavyapashraya
