Researchers have found that individuals with psychosis have dysfunctions in two distinct brain systems.
These systems assist us in predicting or anticipating rewards and in focusing our attention on pertinent internal and external information.A team from Stanford University conducted a recent study that sheds light on the mechanisms underlying the symptoms.
This understanding could assist in developing more effective interventions and therapies for psychosis and other mental health issues that it is associated with.Delusions and other disassociations from reality are symptoms of psychosis. In addition to being a part of disorders like schizophrenia and bipolar disorder, which scientists are still attempting to completely understand, it can also happen on its own.
This work offers a useful model for comprehending the onset and course of schizophrenia, a difficult issue.The 22q11.2 deletion syndrome is a genetic disorder that increases the risk of psychosis and schizophrenia.
The researchers examined the brain scans of 445 individuals who had conditions such as autism, ADHD, early psychosis, and this condition. As a control, they also examined the scans of 411 healthy individuals.The anterior Insula, a vital component of the salience network filter that aids in focusing our attention, and the ventral striatum and associated dopamine-driven pathways, which regulate reward-seeking, were discovered by the team through the use of a machine learning algorithm that revealed differences in brain function between the groups.
This current study confirms the research group’s previous suspicion that the salience network may be implicated and demonstrates that the 22q11.2 deletion syndrome can be a valuable tool for assessing the risk and symptoms of psychosis.The researchers discovered that there were notable differences in these domains related to reward prediction and information filtering in both individuals with psychosis and 22q11.2 deletion syndrome, as well as in individuals with psychosis of unknown etiology.
This similarity strengthens our comprehension of psychosis as a disorder with recognizable and dependable brain markers.This process disrupts cognitive control’s regular operation, giving intrusive ideas the upper hand and leading to symptoms that are identified as psychosis.”Creating medicines based on these findings could be the next step. Although it might be challenging to see the precise impact that various treatments are having on the brain, medical professionals and scientists are now able to pinpoint exactly where they are looking when treating psychosis.
The researchers suggest that existing treatments for psychosis, such as targeted ultrasound and transcranial magnetic stimulation, could be modified to specifically target these brain regions in young individuals who are at risk of developing psychosis.The group Is also eager to lessen stigma and improve services for people who suffer from psychosis.
Experiences involving individuals who are disconnected from reality can be frightening, and it’s not always easy to distinguish between normal and aberrant brain activity.
