In this survey, we explore the history of panic attacks, tracing the evolution of their psychiatric diagnosis over time.

Anxiety is a universal human experience that has been addressed in various ways across literature, philosophy, religion, psychology, and medicine. In this survey, we explore the history of panic attacks, tracing the evolution of their psychiatric diagnosis over time.
The first written records describing anxiety are mentioned in the Epic of Gilgamesh in about 2000 B.C. Even the origin of the word “panic” has ancient roots. The Greeks called groundless fear “panikos.”
Over time, the meaning of panic has changed considerably. What began as an ancient idea associated with sudden, unexplained fear gradually became a clinical concept in psychiatry. This development reflects the changing understanding of anxiety, from early descriptions of fear to the modern diagnosis of panic attacks and panic disorder.
Research on Panic Attacks in the 19th and 20th Centuries
The terms “panic attack” or “panic disorder” are relatively young. These terms only entered psychiatry as a diagnostic entity in the late seventies. Panic disorder emerged as a distinct diagnostic category in modern psychiatric classification, defined by recurrent panic attacks and their characteristic clinical course. Often, this disorder intertwines with agoraphobia, further complicating the clinical picture.
Historically, the technical usage of “panic” diverges from its colloquial counterpart, denoting both abnormal group behaviour and acute anxiety states in individuals. The official psychiatric diagnosis is formalized for the first time in the diagnostic manual, the DSM-III. This classification underscores the evolving understanding of distinct forms of anxiety disorders, separating panic attacks from generalized anxiety.
In psychology, the study of anxiety has its origins in the late 19th century. It was Sigmund Freud who investigated anxiety and, in particular, the panic attacks. Considering today’s criteria, he presented the most detailed description of panic symptoms.
Freud also created the theoretical foundation of this disorder. He recognized the importance of environmental factors without neglecting the hereditary predisposition. Despite his pioneering research, Freud misunderstood the root cause of panic attacks by overestimating the impact of sexuality.
Emil Kraepelin’s Research on Anxiety
Kraepelin, a prominent figure in clinical psychiatry, documented cases of panic attacks and severe agoraphobia. He categorized various anxiety disorders, delineating generalized anxiety characterized by pervasive worry, obsessive thoughts, and compulsions. He also identified phobias, including insect phobias, agoraphobia, specific social phobia, and generalized social phobia.
Walter Canon. Fight-or-Flight Response
Walter Cannon, a physiologist and the intellectual descendant of Darwin, emphasized in 1919 the crucial roles of anger and fear as a survival strategy. His work on the secretion of epinephrine from the adrenal medulla led to the development of the concept of the fight-or-flight response. Despite some misconceptions about chemical transmission, Cannon’s research legacy remains influential in contemporary research on stress.
Sigmund Freud and the Concept of “Anxiety Neurosis”

The first description of anxiety disorders derives from Sigmund Freud. He created the first historical description of disorders that we call today “panic attacks” and “generalized anxiety disorder.” Freud described these disorders using the term “anxiety neurosis” (German: “Angstneurose”). As he wasn’t able to identify in both conditions any visible triggers, he called them “neurosis without conflict.”.
Freud on Panic Attacks
Freud interpreted anxiety attacks as exacerbations of an underlying basic anxiety.
The core symptom of “anxiety neurosis,” as Freud termed the condition, because “all its components can be grouped around the main symptom of anxiety,” is called “anxious expectation.” It is based on “usually latent but constantly lurking anxiety,” which can suddenly “break into consciousness” and “trigger an anxiety attack.” This “consists either solely of the feeling of anxiety without any associated idea or with the immediate interpretation of impending death, ‘blow,’ or impending madness…”.
Based on chronic anxiety… two groups of typical phobias develop… The first group includes the fear of snakes, thunderstorms, darkness, vermin… The other group contains agoraphobia…”.
Freud created the connection between the panic attacks without any obvious reason and phobic panic attacks triggered by certain objects or situations.
In his clinical observation, Freud emphasized the relevance of unconscious conflicts and the role of psychoanalysis to uncover their source.
Freud’s Description of Panic Attacks
On the symptomatic level, Freud’s description of the anxiety neurosis correlates astonishingly well with the current description of panic attacks. In his paper on “anxiety neurosis,” he wrote:
“I append here a list that includes only those forms of anxiety attack that are known to me:
- Disturbances of the heart action, such as palpitation.
- Disturbances of respiration, several forms of nervous dyspnea, attacks resembling asthma, and the like.
- Sweating, often at night.
- Tremors and shivering, easily confused with hysterical attacks.
- Ravenous hunger, often accompanied by vertigo.
- Diarrhea coming on in attacks.
- Locomotor vertigo.
- Congestions, including everything that has been termed vasomotor neurasthenia.
- Paresthesia (numbness). But these seldom occur without anxiety or a similar feeling of discomfort.”
When comparing the above-presented list of symptoms described by Freud with the criteria in the DSM classification, the level of agreement may be quite surprising.
Freud on Aetiology of Panic Attacks
In 1895, Sigmund Freud published a paper entitled “On the Grounds for Detaching a Particular Syndrome from Neurasthenia Under the Description ‘Anxiety Neurosis.” In this paper, he wrote:
“In some cases of anxiety neurosis, no etiology (root cause) at all is to be discovered. It is worth noting that in such cases there is seldom any difficulty in establishing evidence of a grave hereditary taint. But where there are grounds for regarding the neurosis as an acquired one, careful inquiry directed to that end reveals that a set of noxae and influences from sexual life are the operative etiological factors.”
Freud recognised that anxiety symptoms frequently occurred within families, but in cases without an apparent hereditary component he attributed anxiety largely to disturbances of sexual life. From today’s perspective, his emphasis on sexuality as a general explanation for anxiety disorders is considered too narrow. Nevertheless, his attempt to distinguish hereditary vulnerability from acquired psychological factors was an important step in the historical development of theories about panic and anxiety.
From Neurosis to Disorder
Looking back at the history of panic attacks and anxiety disorders, we encounter terms such as neurosis, neurasthenia and hysteria. These concepts belonged to earlier psychiatric classification systems and often combined symptoms that are now assigned to different diagnostic categories. Modern classification gradually replaced these broad historical concepts with more clearly defined disorders based on characteristic patterns of symptoms and clinical course.
DSM III. Differentiating Panic Disorder from Generalized Anxiety Disorder
DSM-III, introduced in 1980, split anxiety disorders into two categories, panic disorder and generalized anxiety disorder (GAD). It was the official birth date of GAD as a diagnostic category.
One major argument for separating spontaneous panic disorder from generalized anxiety was the mistaken belief that they could be distinguished based on their response to medication. This idea was called “pharmacological dissection.”
A double-blind, placebo-controlled study by Klein showed that patients treated with imipramine experienced fewer panic attacks. However, more recent studies by Kahn and colleagues have disproved the notion that panic disorder is uniquely responsive to antidepressants while GAD is not. Contrary to Klein’s findings, Kahn demonstrated that antidepressants are also effective in treating GAD.
History of Panic Attacks. Summary
Modern psychiatric classification distinguishes anxiety disorders according to their characteristic symptoms, triggers, and clinical course. One important distinction is between situational anxiety, as seen in phobias, and anxiety that occurs without a specific external trigger.
Another distinction concerns the course of anxiety. Panic disorder is characterised by recurrent, unexpected episodes of intense anxiety that develop suddenly and reach their peak rapidly. In contrast, generalized anxiety disorder (GAD) involves more persistent and widespread worry and tension that continues over longer periods.
The recognition of these different patterns developed gradually over the history of psychiatry. Earlier concepts grouped various forms of anxiety together, while modern diagnostic systems distinguish panic disorder, generalized anxiety disorder, phobias, and other anxiety disorders as separate clinical conditions.
This development from broad historical concepts such as anxiety neurosis toward more clearly defined diagnostic categories established the foundation for the modern understanding of panic disorder.
