Stockholm Syndrome

August 23, 1973 – Stockholm, Sweden. Two men entered a bank and took four bank workers hostage by gunpoint. The police quickly responded by surrounding the bank but could not act due to concern for the safety of the hostages. The stand-off lasted six days until the police finally negotiated the release of the hostages. During this ordeal, a very strange phenomenon was observed. The hostages had grown emotionally attached to their captors, rejecting rescue attempts and even defending their captors after their freedom. It was clear in subsequent interviews that the hostages had bonded with the criminals, supporting their cause and not minding the fact that they were threatened, abused and were made to fear for their lives. In fact, one woman later became engaged to one of the criminals, while another funded the legal fee for their trials.

Psychiatrist and criminologist Nils Bejerot studied this case and coined the phrase Stockholm syndrome to describe the phenomenon of hostages expressing empathy and sympathy to their captors, leading to bonding with and having positive feelings for them. This seems irrational as bonding is perceived as the product of a positive relationship where two people are loving and caring for each other, not threatening their life. This phenomenon has been well-documented throughout history in hostages, domestic abuse victims, prisoners of war and cult members. One study showed that up to 27% of hostage victims showed evidence of Stockholm syndrome in the U.S.

There are a few explanations for the Stockholm syndrome. The Freudian explanation is that the bonding is an individual’s response to the trauma of being threatened. By rationalising that they are in fact on the same side as the captors, the effect of the trauma is reduced as the victim feels less victimised. Evolutionarily speaking, human beings have always been under the threat of being invaded by a neighbouring tribe or country. This often involved the raping and abduction of women by the aggressors. Victims who would resist and fight back would have more likely been killed (along with their children), while those who responded as per the Stockholm syndrome would have been more likely to survive. It has been observed that the Stockholm syndrome is found more commonly in women.

Stockholm syndrome is a very common feature of human society, found in households in the form of battered-wife syndrome, in groups in the form of hazing and basic military training and in the bedroom in the form of bondage and masochism.

Fugue State

Any computer user would have had an (unfortunate) experience where their computer crashed and all the information there was destroyed in a second. You may still be able to format it and use it without problems, but the data you had on the computer and any customisation you made would be lost. But what if this exact thing could happen to a human being?

There are many types of amnesia, with causes ranging from neurobiological (where trauma to the brain, a drug or some other pathology causes memory loss) to psychogenic (where there is no apparent biological cause for the amnesia). With psychogenic amnesia, one only experiences retrograde amnesia, where they cannot recall memories from the past. However, anterograde amnesia, where you cannot form new memories and keep forgetting what happened, is absent in psychogenic amnesia. Psychogenic amnesia is often caused by extreme stress or a traumatic event. One type of psychogenic amnesia is situation-specific amnesia, as seen in post-traumatic stress disorder (PTSD) that occurs after a severely stressful experience such as war, rape, child abuse or witnessing a brutal death. In this case, the patient tends to only lose memories regarding the event, as if the brain is trying to protect the person from the hurtful memories.

A more interesting and much rarer type of amnesia is global psychogenic amnesia, also known as a fugue state or dissociative fugue. Unlike situation-specific amnesia, patients in fugue states have absolutely no memory of their original identity and personality. Simply put, they (usually) retain all their functions such as speaking and social interactions, but their persona has been wiped out like a formatted computer. Fugue states often develop after severe stress and can happen to anyone. Similar to situation-specific amnesia, the brain blocks all memories of the past in an attempt to protect the person’s psyche. Due to the “deletion” of the previous persona, patients in fugue states often generate new identities and begin wandering (sometimes even travelling to another country) away from the place they lost their memories. This is most likely the brain attempting to leave the environment to avoid the stressor that caused the event. 

Fugue states are often short-lived, lasting from days to months. However, very rarely they can last for years. Once out of a fugue state, the patient recovers all of their past memories but have no recollection of what happened during the fugue state. This creates a hole in their memory. For obvious reasons, this usually causes intense confusion and distress in the patient and treatment is often based around helping the person come to an understanding about the episode and cope with the stressor that caused it.
