Auditory Verbal Hallucinations and Insight

Clinical Principles

The American Academy of Neurology suggests that patients with Charles Bonnet Syndrome have true visual hallucinations with preserved insight, recognizing their hallucinations as unreal 1, 2.
The American Psychiatric Association notes that patients with Parkinson's disease psychosis characteristically show preserved insight initially, recognizing their hallucinations as unreal early in the course 3.
The National Institute of Mental Health indicates that primary psychotic disorders, such as schizophrenia, typically feature impaired insight, with patients believing their hallucinations are real external phenomena 3.

The American Academy of Neurology recommends asking patients directly about their insight into their hallucinations, such as "Do you believe these voices are real, or do you recognize them as coming from your own mind?" 1, 2.
The American Psychiatric Association suggests evaluating the clinical context, including neurodegenerative conditions, ophthalmological causes, medication effects, and metabolic or toxic causes, when insight is preserved 2, 3.

The National Institute of Mental Health notes that deficits in socialization, comprehension, and executive functioning can make some individuals prone to poor social judgment and decision-making even with preserved insight into their hallucinations 5.
The American Psychological Association indicates that depression has a complex relationship with cognition and can mimic or worsen cognitive impairment affecting judgment, independent of hallucination-related insight 4.

The American Academy of Neurology recommends serial assessments across care transitions, as insight and judgment can fluctuate with disease progression, treatment response, or environmental factors 4.
The American Psychiatric Association suggests using both patient self-report and informant versions of assessment tools, as patients may not be aware of their symptoms or difficulties may not be recognized by family 4, 3.
