Schizophrenia is a severe mental disorder characterised by significant disruptions in thought, perception, emotion and social interaction. Classic symptoms of this neurological condition include jumping to conclusions or difficulty adjusting to new information. According to scientists, the symptoms are a result of poor communication between the cerebral cortex and thalamus, which is known as the brain's central switchboard. Recently, a team of researchers from Tufts University School of Medicine and Vanderbilt University School of Medicine found that the neural pathways of schizophrenics work differently as compared to those without the condition when faced with conflicts in decision making. The discovery was made by measuring brain cell activity between the cerebral cortex and thalamus, as volunteers completed ambiguous tasks. How Was The Research Performed? For the research, scientists asked about 40 participants—a mixture of neurotypical individuals and patients with schizophrenia—to correctly choose a target's location based on a sequence of cues. However, the scientists made these cues more or less conflicting. For healthy people, performance was very good even when the conflict was high. But for schizophrenics, there were two different behaviours. They had comparable behaviour to controls when there was little conflict, however, they made many more errors with higher conflict levels, which were tolerated well by controls. The study is important because over the course of evolution, the human brain has developed a system to make decisions in complicated situations. The prefrontal cortex, specifically the dorsolateral and orbitofrontal areas, is responsible for making decisions. His region integrates information from various brain areas, allows for reasoning and judgment, and ultimately guides decisions that align with our goals and desires. How Is Brain Impacted During Schizophrenia?In schizophrenia, the brain experiences structural and chemical changes that disrupt normal thinking, emotions, and behaviour. Research shows that people with schizophrenia often have reduced grey matter volume, particularly in areas involved in memory, emotion, and decision-making, like the hippocampus and prefrontal cortex. Abnormalities in neurotransmitters, especially dopamine and glutamate, also play a key role, leading to symptoms such as hallucinations, delusions, and cognitive difficulties. Connectivity between different brain regions may become impaired, affecting the brain's ability to process information smoothly. These changes typically emerge gradually, often beginning in late adolescence or early adulthood, and vary significantly from person to person.How To Identify Schizophrenia?Schizotypal Personality Disorder is part of Cluster A personality disorders. Other disorders in this cluster include paranoid personality disorder and schizoid personality disorder. Individuals with this condition struggle with social and interpersonal skills, especially when forming close relationships. This occurs alongside eccentric behaviour and perceptual or cognitive distortions.According to the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition), schizophrenia is diagnosed based on a set of specific symptoms. Here's the list of core symptoms:Delusions – strong false beliefs not based in reality (e.g., believing you are being persecuted or have special powers).Hallucinations – hearing, seeing, or sensing things that aren't actually there (most commonly auditory hallucinations).Disorganised speech – frequent derailment, incoherence, or illogical conversation.Grossly disorganised or catatonic behavior – unpredictable agitation, inappropriate behaviour, or lack of movement/responsiveness.Negative symptoms – diminished emotional expression, reduced motivation (avolition), reduced speech (alogia), social withdrawal, or inability to experience pleasure (anhedonia).
