These dramatic cases show how they can spread between people. THE 1518 ‘DANCING PLAGUE’ TANGANYIKA ‘LAUGHTER In July 1518, Mrs Troffea began to dance in the streets of Strasbourg.

The symptoms spread to another 92 pupils, eventually forcing the school to close. Returning home, the children brought the contagion back to their local villages. Within a few months, one village saw 217 people affected and more schools were shut. When the school re-opened the ‘laughter epidemic’ re-emerged.

For many, these behaviours are ‘coping strategies’ that try to address underlying struggles. While coping strategies can sometimes alleviate stress, the 'relief' is short-lived and they do not address the underlying issues. Harmful behaviour must be repeated for any relief to continue. Group settings reinforce and help spread these addictive behaviours in several ways. ‘CO-RUMINATION’ IDENTITY AND COMMUNITY This is where a group of A problem behaviour can to the vulnerable.

Shockingly, they spread even encourage sharing ‘progress’, express anger within peer groups at residential clinics. Here, towards outsiders and share in each other’s anorexia is viewed as a social identity, with pain. Attempted interventions are often seen others pressured to imitate. Deanne Jade, as attacking the identity.9 In the words of one founder of the National Centre for Eating sufferer: Disorders, says: “I had an illness; I had something few “…I ask myself if an eating disorder unit others had; I was special.

The online ‘pro-Ana’ community such content, but the material is still rife and embraces anorexia as a lifestyle choice. They draws in vulnerable people.13 Tips for hiding anorexia “Leave dirty dishes around the house (example: pour a little milk in a bowl...)” “Wear nail polish to hide the discolouring in your nails from lack of nutrients.” The power of suggestion Some popular entertainers spectacularly reveal the mind’s vulnerability to suggestion.Derren Brown persuades his subjects to sit in cold water as though it were a warm bath or drink vinegar like orange juice. He has even convinced some that he was invisible.14 In tests for new medicines, many sick people can experience genuine benefits from taking a new pill. That’s why placebos are always given to one group and the genuine drug to another in order to test its effectiveness. The nocebo effect is the opposite: the suggestion that someone will suffer negative symptoms leads to the symptoms themselves. The nocebo effect can spread by social contagion. THE NOCEBO EFFECT In one experiment, nocebo expert Fabrizio suffer the worst headaches. Benedetti took a group of students into the Analysis of the students’ saliva revealed a Alps. He suggested to one of them that thin change in processes which also occurs in air could produce migraines. This rumour cases of altitude headache.15 Benedetti said: reportedly spread to more than a quarter of “The brain biochemistry changed in the the group and those who heard it began to ‘socially infected’ individuals”.16 Of course, suggestion requires a suggestible subject. But it might only take a little twinge of pain, or some small abnormality, to make someone suggestible and get them to think: “maybe I am unwell”. Even more people are likely to be taken in by the suggestion if they then begin to show symptoms of some kind. We can see four parts to this: Many cases of mass hysteria involve the power of 1. The person is open to suggestion: suggestion. A rumoured gas attack led 35 people to experience 2. The suggestion is made fainting, headaches and nausea.
