The development of panic attacks and social phobia after stroke
1Blacktown Hospital, Blacktown, NSW, Australia.
Summary
A stroke patient experienced panic attacks and social phobia. Brain imaging revealed a right temporal lobe lesion, suggesting a link between the stroke and the new-onset anxiety symptoms.
Area of Science:
- Neurology
- Psychiatry
- Neuroimaging
Background:
- Post-stroke psychiatric disorders are increasingly recognized.
- Anxiety disorders, including panic attacks and social phobia, can manifest after cerebrovascular events.
- The neural underpinnings of these conditions are not fully elucidated.
Purpose of the Study:
- To investigate the potential link between focal brain lesions and the development of panic attacks and social phobia following a stroke.
- To explore the neuroanatomical correlates of post-stroke anxiety disorders.
Main Methods:
- Case study of a patient presenting with new-onset panic attacks and social phobia post-stroke.
- Magnetic Resonance Imaging (MRI) to identify brain lesion location and extent.
- Clinical assessment of psychiatric symptoms.
Main Results:
- The patient developed panic attacks and social phobia after a stroke.
- MRI revealed a focal abnormality in the right temporal lobe with extension into the occipital lobe.
- A pathogenic relationship was proposed between the temporal lobe lesion and the panic attacks.
Conclusions:
- Focal lesions in the temporal lobe may contribute to the development of panic attacks and social phobia after stroke.
- Temporal-limbic structures and associated frontal-subcortical circuits are postulated as the neural basis for panic disorders.
- This case highlights the importance of considering neurological causes for psychiatric symptoms post-stroke.

01:27Panic Disorder
Panic disorder is an anxiety disorder characterized by recurrent and sudden minutes-long episodes of intense fear, known as panic attacks. These attacks may feel like heart attacks and often happen without warning or a specific cause. They can include symptoms such as rapid heart rate, shortness of breath, chest pain, trembling, sweating, dizziness, and a sense of helplessness. During a panic attack, individuals may feel as though they are experiencing a heart attack or are in a...
01:28Social Anxiety Disorder
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.
01:27Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.

01:18Anxiety: Overview
Anxiety is a common mental disorder featuring excessive worry, fear, and apprehension, significantly affecting daily life. People with anxiety disorders experience persistent and intense anxiety, interrupting their everyday functioning.
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.

01:09Preparedness and Phobias
Human fear responses to certain stimuli, such as darkness, heights, deep water, and blood, can often arise despite the absence of direct negative experiences. This phenomenon is rooted in evolutionary psychology, which posits that humans have developed a predisposition to fear stimuli that historically posed significant survival threats. This predisposition, known as preparedness, suggests that early humans who developed a fear of potentially dangerous entities, such as venomous snakes and...
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
