Robbins and Anthony (1982)
Robbins and Anthony, who had historically studied a condition similar to Stockholm syndrome, known as destructive cult disorder, observed in their 1982 study that the 1970s were rich with apprehension surrounding the potential risks of brainwashing. They assert that media attention to brainwashing during this time resulted in the fluid reception of Stockholm syndrome as a psychological condition. Jess Hill (2019)
In her 2019 treatise on domestic violence See What You Made Me Do, Australian journalist Jess Hill described the syndrome as a "dubious pathology with no diagnostic criteria", and stated that it is "riddled with misogyny and founded on a lie"; she also noted that a 2008 literature review revealed "most diagnoses [of Stockholm syndrome] are made by the media, not by psychologists or psychiatrists." In particular, Hills analysis revealed that Stockholm authorities — under direct guidance from Bejerot — responded to the robbery in a way that put the hostages at greater risk from the police than from their captors (hostage Kristin Enmark, who during the siege was granted a phone call with Swedish Prime Minister Olof Palme, reported that Palme told her that the government would not negotiate with criminals, and that "you will have to content yourself that you will have died at your post"); as well, she observed that not only was Bejerots diagnosis of Enmark made without ever having spoken to her, it was in direct response to her public criticism of his actions during the siege.
The condition often starts in childhood, sometimes at an early age, but others report that the highest incidence occurs in the over 40 age group. Females are sometimes reported to be more commonly affected than males, in a 2:1 ratio, although others report that the gender distribution is equal. Clinical Implications
Psoriasis
A recent study has proven the link between geographic tongue (GT) and psoriasis - the presence of geographic tongue can be a predictor of psoriasis. Clinical manifestation of GT and psoriasis can be histologically similar, however a genetic link between the two has been pathogenically identified. Patients with generalised pustular psoriasis and GT both exhibit the c.115 +6T >C mutation in the IL36RN gene. Patients who have GT have been shown to experience a greater severity of psoriasis and have a less positive response to treatment. Oral Manifestations in Patients with COVID-19
Many articles including case reports, case-series and cross-sectional studies have been done since the recent outbreak of COVID-19, causing a global pandemic. These studies have shown that approximately 20% of patients with COVID-19 can present with mucosal manifestations in their oral cavities, including geographic tongue. Geographic tongue is also thought to appear alongside the onset of the regular symptoms of COVID-19. Interleukin-6 (IL-6) is known to be an important biomarker in patients with COVID-19 in relation to a cytokine storm where too many inflammatory cells which have a detrimental effect on organ systems throughout the body. Geographic tongue is associated with elevated levels of IL-6, which possibly helps explain its presentation on confirmed COVID-19 patients.
