Expect emotional warfare where there are high-conflict people.
- High-conflict emotional warfare exists everywhere there are high-conflict people.
- Their strategy is usually to get other people to agree with them on attacking someone else. In mental health terms, this is called "splitting," where you split people into all good and all bad. Splitting is linked to borderline and narcissistic personality disorders.
- High-conflict people dominate by sowing division, at all levels of society — from school boards to state governments.
Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
The Schizotypal Personality<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="5d6b8d5b3aecddd241d26243ac33aeb3"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/hzcIdCdPuUs?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>The <a href="https://www.mayoclinic.org/diseases-conditions/schizotypal-personality-disorder/symptoms-causes/syc-20353919" target="_blank">schizotypal personality</a> is characterized by social anxiety, magical thinking, unusual perceptual experiences, eccentric behavior, a lack of close friends, atypical speech patterns, and suspicions bordering on paranoia. These personality traits that, taken together, resemble the symptoms of schizophrenia.</p><p>A person with <a href="https://www.psychologytoday.com/us/conditions/schizotypal-personality-disorder" target="_blank">schizotypal personality disorder</a> has these personality traits at a level where they begin to interfere with their lives, such as preventing them from forming close relationships, but they lack the hallucinations or delusions commonly associated with full-blown schizophrenia.<sup>1</sup> </p><p>The similarities between this personality type and the symptoms of schizophrenia interested the researchers. Since <a href="https://www.sciencedirect.com/science/article/pii/S2213158215001436" target="_blank">previous studies</a> had shown that the electrophysiological response patterns in the brains of schizophrenic test subjects were often strange (the patterns showed a reduced post-movement beta rebound [PMBR] to be precise), the study looked at the brains of healthy patients to see if a person with a schizotypal personality would have similar brain activity.</p>

Eduard Einstein (left) and his father Albert Einstein. Eduard was a brilliant student who wanted to study psychiatry before being diagnosed with schizophrenia at the age of 20. He lived a difficult life afterwards, dying in an institution at the age of 55.
(Einstein: His Life and Universe)<p>The experiment took 112 test subjects and had them answer a questionnaire, similar to <a href="https://pdfs.semanticscholar.org/e84e/a17580e2afd70777e70294b076ea4f810cb2.pdf" target="_blank">others </a>available <a href="https://psymed.info/schizotypal-personality-disorder-test" target="_blank">online</a>, to determine how many features of the schizotypal personality they had. They were then strapped into a <a href="http://ilabs.washington.edu/what-magnetoencephalography-meg" target="_blank">magnetoencephalography</a> (MEG) machine to have their brains scanned while they performed a simple motor task.</p><p>The volunteers were asked to move their index fingers when given a prompt. The reaction in their brains was recorded. The results were then compared to the answers the test subjects gave in their questionnaires.</p><p>As expected, the higher that a person scored on the schizotypal personality test, the more subdued their PMBR brain activity was—just as it is for patients with schizophrenia. This brain activity was particularly associated with scoring high on the parts of the test geared towards reveling the subject's tendencies to disorganized thinking and difficulty in forming interpersonal relationships.</p>
What are the implications of this study?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xODY0Nzc0MS9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYzMTg5MzIwN30.aBOy-gIsb-lFMyfDax-tzuaBABMz_VrvUTxHd4Kbmlc/img.png?width=1245&coordinates=3%2C252%2C3%2C252&height=700" id="789f0" class="rm-shortcode" data-rm-shortcode-id="acdb45767221dc0d66d873b60c66181c" data-rm-shortcode-name="rebelmouse-image" />
Sample brain scans from the study. Here we see false color images of the brain, with areas that showed higher brain activity during the experiment shown in the most vibrant shades. The top row shows the change above baseline and the bottom shows the change below it. In a test subject with either schizophrenia or many schizotypal traits, the amplitude of the change would be greatly reduced.
(Hunt et al.)<p>The authors conclude the study by explaining</p><blockquote>The finding that diminution of PMBR, previously reported in schizophrenia, is correlated with the severity of schizotypal features across the range observed in the general population, supports the hypothesis that at least some aspects of schizophrenia lie at the extreme end of a normal personality variant.</blockquote><p>This idea, which has been around since the <a href="https://www.ncbi.nlm.nih.gov/pubmed/3332195" target="_blank">seventies</a>, has recently been given more attention as a result of increasing interest in the concept of viewing mental disorders as existing on a gradient. This new view could lead to a better understanding of schizophrenia and perhaps even better treatments over the long run. </p><p>The results might also be of use in reducing the stigma around mental illness, as the study shows that the thought processes of people with schizophrenia are not categorically different from those of many other people. It is a difference of severity, not substance, which seems to separate those suffering from schizophrenia from the people who are merely eccentric. </p><p>Of course, more research is needed. At this moment, scientists aren't sure what neural mechanism even causes this brain activity, let alone how to treat the more extreme manifestations of the reduced activity seen in cases of schizophrenia. </p><p>Our understanding of mental illness has changed drastically over the last few decades as old ideas of what counted as mental illness are thrown out, and new ideas step up to replace old paradigms. The results of this study suggest that the brains of patients with this disease are more similar to the minds of healthy people than had previously been thought. While it will take years of more research before any medical advances are made on this information, our understanding of the people who go through life with this condition can be improved today. </p>
Your brain's heightened sensitivity can make you perceptive and creative. But it's a double-edged sword, researchers find.
People with high IQ are considered to have an advantage in many domains. They are predicted to have higher educational attainment, better jobs, and a higher income level. Yet, it turns out that a high IQ is also associated with various mental and immunological diseases like depression, bipolar disorder, anxiety, ADHD as well as allergies, asthma, and immune disorders. Why is that? A new paper published in the journal Intelligence reviews the literature and explores the mechanisms that possibly underlie this connection.
A study finds an increasing number of Americans live with serious mental issues and their access to healthcare is getting worse.
A team of researchers analyzed 1,280 suicide notes written between 2000 and 2009 to seek a new prevention strategy.
For decades, the mortality rate across the US was in decline. That’s why the results of a 2015 report were so shocking. For the first time in generations, middle-aged white people saw their death rate increase. Husband and wife economists Anne Case and Angus Deaton discovered this disturbing trend, which began back in 1999. The researchers labeled these “deaths of despair,” resulting from suicide, drug or alcohol abuse.
