Low grade inflammation decreases emotional recognition – vaccine model of inflammation
A recent study published in the journal Brain, Behavior, and Immunity, on May 6, 2018, entitled,
“Low-grade inflammation decreases emotion recognition – Evidence from the vaccination model of inflammation” has demonstrated yet another danger of vaccination in how it relates to the brain. To be clear, this study was not conducted to determine the relationship between vaccination and negative health effects but the results point to those dangers nonetheless.
This is because of the effects that inflammation has on the mental state of the person suffering from it. The connection between vaccination comes because vaccines are well known to cause inflammation in recipients, particularly children, that ranges from the moderate levels to outright fatal. Indeed, this inflammation side effect is the reason why researchers used vaccinations to induce inflammation in male test subjects during the course of the experiment.
The researchers write,
The ability to adequately interpret the mental state of another person is key to complex human social interaction. Recent evidence suggests that this ability, considered a hallmark of ‘theory of mind’ (ToM), becomes impaired by inflammation. However, extant supportive empirical evidence is based on experiments that induce not only inflammation but also induce discomfort and sickness, factors that could also account for temporary social impairment. Hence, an experimental inflammation manipulation was applied that avoided this confound, isolating effects of inflammation and social interaction.
The research team ultimately concluded that the study they conducted supports the hypothesis that “immune activation” impairs “theory of mind.” They write,
By utilizing an inflammation-induction procedure that avoided concurrent sicknesses or symptoms in a double-blinded design, the present study provides further support for the hypothesis that immune activation impairs ToM. Such impairment may provide a mechanistic link explaining social-cognitive deficits in psychopathologies that exhibit low-grade inflammation, such as major depression.
While not directly an experiment on the effects vaccines have on the ability to function at a full cognitive and emotional level, there is some evidence to be gained by the results of this study. After all, one of the many noticeable side effects of vaccines is an impaired cognitive and social capability.
