Suffering episodes of bullying is linked to a greater possibility of having hallucinations, paranoia and alterations in thinking or behavior. Psychosis detectable by measuring the levels of a neurotransmitter

.

I study

One established it study conducted by scientists from the University of Tokyo published in Nature who used magnetic resonance spectroscopy, or MRS (a type of radiological imaging used to depict the structure and function of the brain), to measure glutamate levels in the anterior cingulate cortex of the brain (ACC), a region that plays a crucial role in emotion regulationdecision making and cognitive control.

Glutamate

The scientists monitored glutamate levels because individuals experiencing their first episode of psychosis (or suffering from schizophrenia) they have lower than normal levels of glutamatea neurotransmitter involved in a wide range of functions, including learning, memory and mood regulation. Alterations in glutamate levels have been implicated in various psychiatric disorders, including schizophrenia, depression, and anxiety.
Psychosis is a mental state characterized by loss of contact with reality, inconsistent speech and behavior and/or hallucinations and delusions.

Bullying incidents

Glutamate levels were measured in Japanese adolescents at first and second time points. Bullying victimization was monitored via questionnaires completed by the adolescents themselves. The researchers then used formal psychiatric measures to assess the experiences of bullying victims (e.g. counting the frequency of incidents, assessing the nature of events and physical or verbal aggression, measuring the impact

ct on mental health in general).

The results

They found that bullying was associated with higher levels of psychotic experiences subclinical in early adolescence and that higher levels of these experiences were in turn associated with lower glutamate levels. Subclinical episodes are defined as episodes that present symptoms that approximate psychosis, but do not meet all the criteria for a clinical diagnosis of a psychotic disorder, such as schizophrenia. These symptoms or experiences may include hallucinations, paranoia, or radical changes in thinking or behavior and can have a significant impact on the well-being and lives of children, even in the absence of a diagnosis of psychotic disorder.

Future interventions

The study of these subclinical psychotic experiences is important for us to understand the early stages of psychotic disorders and to identify them individuals which could be more at risk to develop a clinical psychotic illness later, said lead study author Naohiro Okada, a professor at the University of Tokyo’s International Research Center for Neurointelligence. Although Okada’s group identified a potential target for pharmacological interventions (glutamate), he added that non-pharmacological interventions such as cognitive behavioral therapy or mindfulness-based interventions can also serve to counteract this neurotransmitter imbalance.
