All are features of psychosis except
**Core Concept**
Psychosis is a disconnection from reality, characterized by hallucinations, delusions, and disorganized thinking. It is a feature of various psychiatric disorders, including schizophrenia, bipolar disorder, and major depressive disorder. The pathophysiology of psychosis involves abnormalities in neurotransmitter systems, particularly dopamine and glutamate.
**Why the Correct Answer is Right**
The correct answer is a feature of psychosis because it is a manifestation of disorganized thinking and a break from reality. Hallucinations and delusions are common in psychotic disorders, and they can be auditory, visual, or tactile. The disorganized thinking and behavior seen in psychosis can be due to abnormalities in the limbic system, particularly the hippocampus and amygdala. The dopamine system, particularly D2 receptors, is also implicated in the pathophysiology of psychosis.
