Panic Disorder

Panic 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...

Traumatic Memory

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual remembers mundane...

Post-traumatic Stress Disorder

Post-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.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events, are a...

Flashbulb Memory

Flashbulb Memory

A flashbulb memory is a highly vivid and detailed memory, often linked to events of significant emotional impact. These memories stand out in contrast to everyday memories due to their clarity and the precision with which they are recalled. The strong emotions associated with the event act as a catalyst, ensuring that specific details, such as one's location, actions, and even peripheral elements, are etched into memory with remarkable accuracy. For example, many people can vividly recall where...

Summary

Panic Disorder (PD) is linked to decreased working memory performance. Patients with PD showed significantly lower scores on a visual memory task compared to healthy individuals.

Area of Science:

Neuroscience
Psychiatry
Cognitive Psychology

Background:

Panic Disorder (PD) presents with both somatic and cognitive symptoms.
Cognitive functions like attention, memory, and perception may be impaired in PD.
Maladaptive cognition is a key feature associated with anxiety disorders.

Purpose of the Study:

To investigate working memory deficits in patients diagnosed with Panic Disorder.
To compare the working memory performance of PD patients with healthy controls.

Main Methods:

Eleven patients with Panic Disorder (DSM-IV-TR) and nine healthy controls participated.
The Panic and Agoraphobia Scale assessed disorder severity.
Working memory was evaluated using the Delayed Match to Sample (DMS) task from the Cambridge Neuropsychological Test Automated Battery (CANTAB).

Main Results:

A significant difference in performance was observed between groups on the DMS task.
Healthy controls achieved higher accuracy (M=92.22) compared to PD patients (M=86.06).
This indicates impaired delayed visual memory and recognition in the PD group.

Conclusions:

Panic Disorder is associated with deficits in working memory.
Impaired performance on the DMS task suggests difficulties in maintaining stable mental representations.
These findings highlight the role of working memory dysfunction in the pathophysiology of PD.
