Schizophrenia is a complex, chronic mental disorder marked by symptoms such as hallucinations, delusions, social withdrawal, and emotional flatness. Diagnosis according to the DSM-5 requires a decline in social and occupational functioning for at least six months, alongside at least two specific symptoms, including one positive symptom. Neuroimaging studies reveal reduced gray matter in critical brain areas like the frontal and temporal lobes, linking these structural changes to neurotransmitter imbalances, especially in dopamine levels, which are crucial for understanding the disorder’s impact on brain function.

Genetic research has highlighted the complexity of schizophrenia, identifying it as a highly polygenic condition with numerous genetic loci that intersect with other psychiatric disorders such as bipolar and major depressive disorder. This genetic data, along with insights into neurotransmitter and immune system interactions, suggests a neurodevelopmental basis for schizophrenia, exacerbated by environmental factors. Ongoing research is paving the way for more precise and effective treatment approaches, deepening our understanding of its neurobiological mechanisms and potentially enhancing management strategies for this debilitating illness.
