Understanding Mass Hysteria

Understanding Mass Hysteria

A phenomenon referred to as mass hysteria, also recognized as epidemic hysteria, mass psychogenic disorder, or mass sociogenic sickness, occurs when individuals within a tightly-knit group exhibit hysterical behaviors. The term ‘hysteria’ denotes an overwhelming and often uncontrollable emotional state. The root causes of mass hysteria are frequently unfounded, leaning more towards a mental ailment rather than a physical one.

Those undergoing mass hysteria typically display features of collective delusion driven by an unwavering belief in an unusual notion. Essentially, mass hysteria manifests as hysterical symptoms observed in a collective setting. The anxiety instilled in a significant population, primarily through media influence, leading to the conviction that societal norms are under threat, is termed moral panic.

Types Of Mass Hysteria

  • Mass anxiety hysteria: Individuals who are part of the same close-knit, sometimes secluded group or community tend to exhibit this kind. It is characterized by abrupt tension and other anxiety-related symptoms that “spread” and go away quite rapidly.
  • Mass motor hysteria: This kind is more likely to manifest in those who have been under constant stress and strain. It features erratic motor (movement) symptoms that vary progressively from person to person and frequently persist for weeks at a time.


Psychological anguish is the primary cause of hysteria and can arise for several causes. The primary theory is that it is caused by an environmental occurrence that impacts a group of individuals, leading to the common symptoms of hysteria.

These people might sometimes become so emotionally and socially numb or blind from the stress of a pandemic or other disaster that they are unable to handle it. Medical professionals think that patients experience actual pain even though it is a mental disorder rather than a physical illness. 

Causes Of Mass Hysteria

Causes Of Mass Hysteria

Some potential causes include:

  • Groupthink: Groupthink, a psychological phenomenon, emerges when a group swiftly adopts an opinion aligning with the collective consensus without critically evaluating information. Though commonly associated with business, politics, and policymaking, groupthink is relevant to the psychology of collective phobias and mass hysteria. Mass hysteria can be viewed as an extreme manifestation of groupthink. Groupthink tends to arise frequently in the presence of a respected or persuasive leader, encouraging members to align with their viewpoint.
  • Stress: Experiencing intense stress or trauma may also contribute to the onset of mass hysteria. In times of extreme stress, individuals might mistakenly attribute feelings associated with stress to physical or environmental causes. Collective trauma can lead people to manifest psychogenic symptoms.
  • Social Pressure: Social pressure may influence the manifestation of symptoms linked to mass hysteria. When numerous individuals display similar symptoms, others may consciously or unconsciously feel pressured to exhibit the same. The fear of others being unwell can prompt individuals to overly focus on physical sensations, which may then be ascribed to a collective illness.

Treatment for Mass Hysteria


There is no recognized therapy for widespread psychogenic disease.

Therapy for conversion disorder, together with comfort and sympathetic recognition of symptoms, can often lead to improvement. In general, experts advise using a similar tack when dealing with cases of widespread hysteria.

In summary, physical symptoms may usually be relieved by determining the underlying cause of your stress and taking appropriate action to address it. A safe environment to develop and put new coping mechanisms for persistent stress in your life into practice is provided by therapy.

One more crucial step on the road to recovery? keeping your distance from the epicenter. Finding a sense of calm that encourages a quicker recovery can be facilitated by taking a break from talking about or sharing the same symptoms with other people.

  1. The nation’s capital was gripped by fear in 2001, courtesy of the infamous ‘Monkey Man’ or Kala Bandar. Reports surfaced of a creature, half-monkey, half-man, terrorizing the streets of New Delhi. Descriptions varied, with some claiming the creature had mechanical claws, while others insisted it wore a helmet.

Authorities became concerned about the surge of people, fearing the consumption of the contaminated stream water could lead to illness.
