Step 1: Understanding the Concept:
Panic Disorder is a major classification within anxiety disorders characterized by recurrent, unexpected panic attacks.
A panic attack is defined in psychology as a discrete period of intense fear or apprehension that develops suddenly and reaches a peak within a few minutes.
These attacks are not just emotional; they involve a significant physiological "alarm" reaction in the body, which is often misperceived by the individual as a medical emergency, such as a heart attack.
The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) highlights that Panic Disorder involves persistent concern about having additional attacks or their consequences.
Step 2: Detailed Explanation:
The scenario described in the question provides a classic clinical presentation of Panic Disorder through Riya's experience.
The physical symptoms mentioned—racing heart (palpitations), breathlessness (dyspnea), and dizziness (vertigo)—are results of the sudden activation of the sympathetic nervous system.
When this system is triggered without an external threat, the brain attempts to interpret the danger, leading to the cognitive fear of dying or losing control.
Riya's avoidance of crowded places and public transport is a secondary development known as agoraphobic behavior, where she fears being in situations where escape might be difficult or help might not be available during an attack.
Let us analyze why the other options are incorrect:
(A) Hallucinations: These are sensory perceptions in the absence of external stimuli, such as hearing voices or seeing things.
Hallucinations are characteristic of psychotic disorders like Schizophrenia or organic brain syndromes, not anxiety-based Panic Disorder.
(C) Loss of memory: Also known as amnesia, this is usually associated with dissociative disorders or neurological trauma.
While high anxiety can cause a person to feel "disoriented," memory loss is not a diagnostic criteria for Panic Disorder.
(D) Multiple personalities: This is the hallmark of Dissociative Identity Disorder (DID), where an individual manifests two or more distinct personality states.
It is a dissociative process rooted in trauma and is unrelated to the physiological fear response of panic attacks.
Step 3: Final Answer:
By comparing the diagnostic criteria of various psychological disorders, it becomes clear that Riya's "sudden episodes of intense fear" and "physical discomfort" are the defining characteristics of her condition.
The symptoms of heart racing and fear of death directly map onto the sudden episodes mentioned in option (B).
Therefore, the most strongly associated symptom is (B).
