Jerusalem syndrome is a group of mental phenomena involving the presence of either religiously themed obsessive ideas, delusions or other psychosis-like experiences that are triggered by a visit to the city of Jerusalem. It is not endemic to one single religion or denomination but has affected Jews, Christians, and Muslims of many different backgrounds.
The best known, although not the most prevalent, manifestation of Jerusalem syndrome is the phenomenon whereby a person who seems previously balanced and devoid of any signs of psychopathology becomes psychotic after arriving in Jerusalem. The psychosis is characterised by an intense religious theme and typically resolves to full recovery after a few weeks or after being removed from the area. The religious focus of Jerusalem syndrome distinguishes it from other phenomena, such as Stendhal syndrome in Florence or Paris syndrome for Japanese tourists.
In a 2000 article in the British Journal of Psychiatry, Bar-El et al. claim to have identified and described a specific syndrome which emerges in tourists with no previous psychiatric history. However, this claim has been disputed by M. Kalian and E. Witztum. Kalian and Witztum stressed that nearly all of the tourists who demonstrated the described behaviours were mentally ill prior to their arrival in Jerusalem. They further noted that, of the small proportion of tourists alleged to have exhibited spontaneous psychosis after arrival in Jerusalem, Bar-El et al. had presented no evidence that the tourists had been well prior to their arrival in the city. Jerusalem syndrome is not listed or mentioned in the DSM nor in the ICD.
Jerusalem syndrome has previously been regarded as a form of hysteria, referred to as “Jerusalem squabble poison”, or “fièvre Jerusalemmiene”. It was first clinically described in the 1930s by Jerusalem psychiatrist Heinz Herman, one of the founders of modern psychiatric research in Israel. Whether or not these behaviors specifically arise from visiting Jerusalem is debated, as similar behaviors have been noted at other places of religious and historical importance such as Mecca and Rome. It is known that cases of the syndrome had already been observed during the Middle Ages, since it was described in the itinerary of Felix Fabri and the biography of Margery Kempe. Other cases were described in the vast literature of visitors to Jerusalem during the 19th century.
The classic Jerusalem syndrome, where a visit to Jerusalem seems to trigger an intense religious psychosis that resolves quickly or on departure, has been a subject of debate in the medical literature. Most of the discussion has centered on whether this definition of the Jerusalem syndrome is a distinct form of psychosis, or simply a re-expression of a previously existing psychotic illness that was not picked up by the medical authorities in Israel.
In response to this, Bar-El et al. classified the syndrome into three major types to reflect the different types of interactions between a visit to Jerusalem and unusual or psychosis-related thought processes. However Kalian and Witztum have objected, saying that Bar-El et al. presented no evidence to justify the detailed typology and prognosis presented and that the types in fact seem to be unrelated rather than different aspects of a syndrome.
Type I
Jerusalem syndrome imposed on a previous psychotic illness. This refers to individuals already diagnosed as having a psychotic illness before their visit to Jerusalem. They have typically gone to the city because of the influence of religious ideas, often with a goal or mission in mind that they believe needs to be completed on arrival or during their stay. For example, an affected person may believe himself to be an important historical religious figure or may be influenced by important religious ideas or concepts (such as causing the coming of the Messiah or the second coming of Christ).
Type II
Jerusalem syndrome superimposed on and complicated by idiosyncratic ideas. This does not necessarily take the form of mental illness and may simply be a culturally anomalous obsession with the significance of Jerusalem, either as an individual, or as part of a small religious group with idiosyncratic spiritual beliefs.
Type III
Jerusalem syndrome as a discrete form, uncompounded by previous mental illness. This describes the best-known type, whereby a previously mentally balanced person becomes psychotic after arriving in Jerusalem. The psychosis is characterised by an intense religious character and typically resolves to full recovery after a few weeks or after being removed from the locality. It shares some features with the diagnostic category of a “brief psychotic episode”, although a distinct pattern of behaviors has been noted.
Anxiety, agitation, nervousness and tension, plus other unspecified reactions.
Declaration of the desire to split away from the group or the family and to tour Jerusalem alone. Tour guides aware of the Jerusalem syndrome and of the significance of such declarations may at this point refer the tourist to an institution for psychiatric evaluation in an attempt to preempt the subsequent stages of the syndrome. If unattended, these stages are usually unavoidable.
A need to be clean and pure: obsession with taking baths and showers; compulsive fingernail and toenail cutting.
Preparation, often with the aid of hotel bed-linen, of a long, ankle-length, toga-like gown, which is always white.
The need to shout psalms or verses from the Bible, or to sing hymns or spirituals loudly. Manifestations of this type serve as a warning to hotel personnel and tourist guides, who should then attempt to have the tourist taken for professional treatment. Failing this, the two last stages will develop.
A procession or march to one of Jerusalem’s holy places, ex:The Western Wall.
Delivery of a sermon in a holy place. The sermon is typically based on a plea to humankind to adopt a more wholesome, moral, simple way of life. Such sermons are typically ill-prepared and disjointed.
Paranoid belief that a Jerusalem syndrome agency is after the individual, causing their symptoms of psychosis through poisoning and medicating.
Bar-El et al. reported 42 such cases over a period of 13 years, but in no case were they able to actually confirm that the condition was temporary.
During a period of 13 years (1980–1993) for which admissions to the Kfar Shaul Mental Health Centre in Jerusalem were analysed, it was reported that 1,200 tourists with severe, Jerusalem-themed mental problems were referred to this clinic. Of these, 470 were admitted to hospital. On average, 100 such tourists have been seen annually, 40 of them requiring admission to hospital. About three and a half million tourists visit Jerusalem each year. Kalian and Witztum note that as a proportion of the total numbers of tourists visiting the city, this is not significantly different from any other city.
