Is psychosis a functional disorder?
Psychiatric disorders are closely related to functional disturbances, which constitute an important pathological basis. However, the two cannot be simply equated, as the causes and manifestations of psychiatric disorders are more complex and multifactorial. A detailed analysis is as follows:

The onset of psychiatric disorders is often accompanied by significant physiological dysfunction, particularly abnormalities in neurotransmitter systems and brain function. For example, imbalances in neurotransmitters such as dopamine and serotonin can lead to impairments in perception, thinking, and emotion; functional abnormalities in brain regions such as the prefrontal cortex and hippocampus can also affect cognitive judgment and emotional regulation. These functional disturbances are key factors underlying symptoms such as hallucinations and delusions.
However, psychiatric disorders are not merely the result of functional disturbances, but rather arise from the interaction of biological, psychological, and social factors. Genetic susceptibility, prenatal infections, psychological trauma, and chronic stress may all trigger or exacerbate the condition on the basis of existing functional impairments.
Understanding psychiatric disorders requires consideration of both the pathological mechanisms of functional disturbances and the multifactorial nature of their etiology. In daily life, maintaining regular作息 (sleep-wake cycles), a balanced diet to support stable neural function, and fostering an inclusive psychological environment can help reduce the risk of developing psychiatric conditions and support overall mental and physical recovery.
