Acrophobia

Acrophobia is a specific phobia marked by intense, persistent fear of heights or situations perceived as risking a fall. It can cause avoidance and distress beyond ordinary caution.

Specific phobia: An anxiety disorder involving persistent, excessive fear of a particular object or situation. Acrophobia is classified as a specific phobia focused on heights.
Cognitive behavioral therapy: A structured psychotherapy that changes unhelpful thinking and behavior patterns. It commonly combines exposure with work on exaggerated danger predictions in acrophobia.
Diagnostic and Statistical Manual of Mental Disorders: The American Psychiatric Association's classification and diagnostic manual for mental disorders. Its criteria define when persistent height fear qualifies as a specific phobia.
Avoidance behavior: Actions taken to evade feared cues, situations, or anticipated distress. Avoidance can restrict travel, work, recreation, and access to elevated places.
Height vertigo: Dizziness or disorientation experienced at height, often involving altered visual and postural cues. Its relationship to fear raises questions about whether sensory instability triggers or follows anxiety.
Fear conditioning: Learning in which a previously neutral cue comes to elicit fear after association with an aversive event. A fall or frightening height experience can condition fear to height-related cues.
Virtual reality therapy: A treatment method that uses simulated environments to practice confronting feared situations. Virtual heights can provide a controllable setting for exposure practice.
Anxiety: A state of apprehension and heightened anticipation of possible threat. Acrophobia is an anxiety condition in which anticipated danger is tied to heights.
Functional impairment: Difficulty carrying out important activities or social roles because of a health condition. The clinical significance of acrophobia depends partly on disruption to a person's life.
Postural control: The regulation of body position and balance during standing and movement. Studies examine whether altered stance at heights contributes to fear or results from it.
