Anxiety

Anxiety: Overview and Individual Variability

• Anxiety definition: apprehension, uneasiness, uncertainty, or dread arising from a real or perceived threat. It doesn’t have to make sense to you or I.

• Individual differences: what makes one person anxious may not affect another; anxiety is a personal response shaped by experiences and context.

• Triggers can be varied:

  • Loud noises or even non-loud stimuli if focus is intense.

  • Deviation from routine or schedule (e.g., someone on the spectrum may be anxious if routine changes).

  • Being late or changing expectations around time.

• Time perception examples:

  • “Your hour” vs “my hour” when friends say they’ll pick you up in an hour; one person’s hour may feel longer or shorter than another’s.

  • “Mommy minute” vs a clock minute; a minute’s length can be perceived differently.

• Normal vs excessive anxiety:

  • Normal anxiety is often necessary for survival (vigilance, response to potential danger).

  • Excessive or misaligned anxiety can arise in non-threatening situations (e.g., selfie at a National Park near buffalo).

• Anxiety vs fear:

  • Fear is a reaction to a specific, present danger (e.g., a snake approaching).

  • Anxiety is anticipation or concern about a potential threat, which can exist without immediate danger.

• Real-world examples from hiking:

  • Anticipating seeing wildlife (moose, mountain lion) can provoke anxiety; the presence of danger (snake on a trail) can provoke fear.

  • Encountering a rattlesnake on a switchback may trigger a shift from anxiety to fear as the danger becomes imminent.

• Levels of anxiety and how they affect function:

  • Mild anxiety: perceived reality remains intact; perception is sharp; due dates or deadlines can increase wproductivity; small rituals (e.g., “stop-and-dash”) help.

  • Moderate anxiety: perceptual field narrows; heightened alertness; learning and problem-solving may improve but teaching may be less effective; early signs include restlessness (e.g., finger tapping, fidgeting).

  • Severe anxiety: perceptual field significantly decreases; difficult to attend to environment; problem solving and learning are impaired; safety and basic needs become priority; possible ritualistic behaviors or non-responsiveness.

  • Panic attack: severe disruption of processing; distorted perception and rational thought; may include delusions or hallucinations; risk of medical complications (e.g., potential heart issues); requires immediate safety measures and often PRN medication; environment may need to be stabilized and others redirected away from the patient.

• Physiologic responses associated with increasing anxiety levels:

  • Elevated heart rate (HR)

  • Diaphoresis (sweating)

  • Jitteriness and restlessness

  • Increased blood pressure (BP)

  • Increased respiratory rate

  • Muscle tension and agitation

• Safety and care considerations in clinical settings:

  • Always assess for self-harm or harm to others across anxiety levels.

  • Move to a quieter, less stimulating environment if possible; reduce sensory input (e.g., turn lights down).

  • Reassure and stay with the patient; adjust care planning to reflect their current state (e.g., delay non-essential tasks).

  • Use stress-reduction activities and provide simple teaching targeted to current capabilities (e.g., calm breathing, brief coping strategies).

  • For escalating patients, consider grouping strategies to de-escalate; when necessary, one-on-one attention and safety planning take priority.

• Practical teaching and coping strategies for mild to moderate anxiety:

  • Deep breathing exercises and counting strategies.

  • Use of tactile or fidget tools (e.g., coins or small devices) to channel nervous energy without causing disruption.

  • Visualization and progressive relaxation techniques.

  • Simple, non-threatening instructions if teaching is needed (e.g., “sit down, take this PRN medication”).

• Behavioral strategies observed in everyday life:

  • Text-based or timely communication preferences (e.g., “text me when you leave your house” or “your hour vs my hour”) to reduce anticipatory anxiety.

  • Preference for early preparation and control over timing.

  • Preference for predictable routines and structured activities.

• Defensive mechanisms and coping behaviors:

  • Defense mechanisms used to protect self from anxiety include denial (e.g., “I’m not anxious”), projection, and other generalized mechanisms.

  • Clinicians may assess for use of defense mechanisms to tailor supportive interventions.

• Educational and clinical implications:

  • Anxiety disorders and related conditions overlap with mood disorders, substance use, and other psychiatric conditions; many patients have comorbidity (dual diagnosis).

  • In exam-oriented teaching, common categories include separation anxiety, panic, agoraphobia, phobias, social anxiety, generalized anxiety disorder, substance-induced anxiety, and anxiety related to medical conditions.

• Transition note:

  • This section leads into a broader discussion of specific anxiety disorders and related clinical presentations, which is followed by planning for safety, assessment tools, and treatment options.

Separation Anxiety Disorder

• Typically diagnosed before age 18.

• Definition: developmentally inappropriate level of concern or anxiety about separation from a significant other.

• In young children (infants/toddlers), some separation anxiety is normal and developmentally appropriate.

• In older children (e.g., third or fourth grade) who cling to parents during procedures like drop-off, this may indicate a more pronounced separation anxiety disorder.

Panic Disorder and Panic Attacks

• Panic disorder is characterized by recurrent panic attacks, not just occasional anxiety that turns into a panic episode.

• Panic attacks involve sudden surges of intense fear with physical symptoms (e.g., chest pain, palpitations, shortness of breath) and cognitive overwhelm.

Agoraphobia and Phobias

• Agoraphobia: fear of places or situations where escape might be difficult or embarrassing; common examples include outdoors, bridges, or crowded or open spaces.

• Other phobias: fear of a specific object, activity, or situation (e.g., fear of animals, heights, spiders).

• Phobias can produce significant impairment in functioning and may require therapeutic strategies such as systematic desensitization.

• Practical note on desensitization: systematic desensitization is a potential approach for phobias; choices depend on the individual’s trauma history and exposure needs.

Social Anxiety Disorder (Social Phobia)

• Severe anxiety or fear triggered by exposure to social or performance situations.

• Performance contexts (e.g., public speaking, musical performance) are common triggers.

• Management may include non-pharmacological approaches (visualization, deep breathing) and, in some cases, pharmacologic options like beta blockers to reduce heart rate during performance.

• Caution: avoid over-reliance on medications before trying coping strategies; emphasize skills-first approaches for exam settings.

Generalized Anxiety Disorder (GAD)

• Essential feature: excessive, uncontrollable worry lasting months (not just a single anxious episode).

• Worries may anticipate disaster and manifest as restlessness and irritability.

• GAD can be related to multiple stimuli and contexts; the worry is persistent and difficult to control.

Substance-Induced Anxiety Disorder and Dual Diagnosis

• Anxiety, panic attacks, or obsessive-compulsive symptoms can develop with substance use (ETOH, cocaine, heroin, hallucinogens, etc.).

• Dual diagnosis: many individuals have co-occurring mental health disorders and substance use disorders.

• Clinical question: which came first—the mood/anxiety symptoms or the substance use? treatment must address both.

Anxiety and Medical Conditions (Mimics or Triggers)

• Important to rule out medical causes of anxiety-like symptoms:

  • Hyperthyroidism

  • Pulmonary embolism (classic presenting factor can be anxiety-like symptoms; acute dyspnea/sudden chest symptoms may be misinterpreted as anxiety)

  • Cardiac dysrhythmias (e.g., supraventricular tachycardia) that can produce a racing heart and anxiety sensations

• These conditions require medical evaluation and management separate from psychiatric care.

Practical Implications for Practice and Exam Preparation

• Recognize the spectrum from mild to panic with corresponding functional impact and safety considerations.

• Distinguish normal anxiety from clinically significant anxiety that impairs functioning.

• Use tiered intervention: safety assessment; environmental modification; simple coping strategies; and appropriate referral/turther treatment when needed.

• Be mindful of comorbidity with mood and substance use disorders when planning treatment.

• Understand that context, history, and individual differences shape anxiety responses and coping styles.

Transition to Depression

• The discussion of anxiety often transitions to depression in course materials, reflecting the high comorbidity and overlapping symptomatology between anxiety disorders and depressive disorders.

Key Takeaways for Study and Clinical Practice

• Anxiety is a multi-level, context-dependent phenomenon with physiological, cognitive, and behavioral manifestations.

• Normal anxiety serves protective functions; problems arise when anxiety becomes disproportionate to the situation or severely impairs functioning.

• Clinically, assess level of anxiety, safety risks, and possible comorbid conditions; tailor interventions to the patient’s current level (mild through panic).

• Basic, non-threatening teaching and coping strategies are most effective at mild to moderate levels; severe and panic states require safety-focused, one-on-one, and possibly pharmacologic management.

• Different anxiety disorders have characteristic features but share common pathways (e.g., hyperarousal, distress, avoidance) and can co-occur with substance use disorders or medical conditions.
