Researchers from various academia are warning against media coverage of suicides and terror attacks because of the propensity toward copy-cats and the audience developing post-traumatic stress disorder (PTSD).

Both studies recommend that “certain” types of media be avoided because of the damage they can cause to the viewer or reader’s psyche – causing them to have a propensity toward suicide or PTSD.

In order to better predict suicidal tendencies in individuals, researchers from Ghent University (GU) in Belgium and Columbia University (CU) are using “in-vivo neuroimaging studies indicate a biological basis” and genome samples to decipher biomarkers that can tell if an individual has a propensity toward considering suicide.

Authors of the study assert that suicide is “heritable” and knowing this is “crucial” to preventing suicidal behavior.

J. John Mann, co-author of the study, explains that suicide is “an interaction between environmental stressors and a susceptibility to suicidal behavior” called traitlike diathesis (TD).

Mann points toward knowing which “genes [they] are and how they exert their effect.”

According to neuroimaging collected by the researchers, they were able to link “brain circuitry and localized changes in neurochemistry to the regulation of mood, reactive aggression, and decision making in particular.”

Essentially, genetic propensity aided by environmental factors could lead to suicide and if these scientists could identify biomarkers they could predict whether or not an individual would attempt to or even consider committing suicide and implement preventative measures.

Researchers from CU and the New York State Psychiatric Institute (NYSPI) have released a report claiming that “newspaper stories alone would drive a teenager to suicide” and there are copy-cat cases of self-harm that are perpetuated by media coverage of the issue.

Although the authors of the study admit that their findings “do not prove that the newspaper stories were to blame” they asserted that their research “adds to evidence that certain types of media coverage of a suicide can sometimes create a ripple effect.”

Madelyn Gould, professor at CU and affiliated with the NYSPI said that “if vulnerable teens read details about another young person’s suicide, they might identify with that situation and be affected.”

The researchers warn against “using newer forms of internet media” because it is “less regulated, more volatile and more interactive media might have an even greater effect, particularly because young people are not only major consumers of these forms of media, but also the creators of their content.”

Gloud and her team analyzed data which revealed “48 teen suicide clusters that occurred across the United States between 1988 and 1996. Each cluster involved a community where between three and 11 teenagers killed themselves within a six-month period.”

To prove their theory, the researchers “examined local newspaper coverage of the first suicide in those clusters, and compared it with coverage of isolated teen suicides that occurred in the same state.”

The cluster suicides were shown to have more coverage in media with the likelihood that “photos contain[ing] graphic details about the method of suicide”.

Gould maintains that these mysterious clusters could be indicative of “factors that might drive teen suicide. Although we’re all aware of clusters, and towns have been traumatized by them, we don’t understand what triggers them. The good news is that media coverage of suicides is something that can be changed. And efforts are already underway.”

The lead author warns journalists “to be aware [of] the way they talk about suicide matters.”

Last December, researchers at the University of California at Irvine have found that media coverage of a terrorist attack is just as powerful an effect on the human psyche as being at the event itself.

The team at UC Irvine observed that post-traumatic stress disorder (PTSD) could be developed within an individual’s mind from simply watching media coverage on a terroristic event.

The study entitled, “Media’s Role in Broadcasting Acute Stress Following the Boston Marathon Bombings”, claims that “media coverage of collective traumas may trigger psychological distress in individuals outside the directly affected community.”

Findings concluded that “repeated bombing-related media exposure was associated with higher acute stress than as with direct exposure. Media coverage following a collective trauma can raise the severity of the stress. This unique study compares the impact of direct vs. indirect media-based community trauma exposure on acute stress responses.”

Roxane Cohen, co-author of the study cautions Americans against being “repeatedly exposed throughout the day to a variety of sources of media.”

This internet-based survey polled 5,000 Americans in the 2 to 4 weeks after the Boston Marathon Bombing (BMB).

Of those participants, 1% was at the event; 9% knew someone close to them who attended the event; another 9% were directly affected by the event.

Whether participants were exposed to the BMB by television broadcasts, radio news or internet, it became clear to researchers that there was an acute rise in stress that was palatable for both those who learned about the event and those who were there.

It was surmised that if a person consumed more than 6 hours of news about the BMB or bombing-related news coverage, that person was 9 times more likely to have symptoms of high acute stress (HAS).

The 5th addition of the Diagnostic & Statistical Manual of Mental Disorders (DSM-5) explains that there are many types of PTSD that an individual can develop throughout their life.
Children as young as 6 have been diagnosed with preschool PTSD .
Dissociative PTSD is described as:

• Having direct exposure
• Learning from a friend or close relative
• Extreme indirect exposure

Should the individual have reoccurring, involuntary memories, traumatic nightmares, dissociative reactions and intense distress after exposure it is understood that they are suffering from PTSD.

Zoloft, one of the psychotropic drugs administered to sufferers of PTSD has been known to cause :

• Suicidal thoughts
• Birth defects
• Hostility and aggression
• Withdrawal
• Hallucinations
• Death

Paxil is known to cause all of the same “side effects” as Zoloft.
