Changes in regional cerebral blood flow associated with psychosis in patients with Alzheimer’s disease

Key Points

• To explore the relationship between regional cerebral blood flow and psychosis in Alzheimer’s disease patients.
• Observed patients with Alzheimer’s disease
• Measured regional cerebral blood flow (CBF)
• Assessed cognitive impairment levels
• Psychosis correlated with increased cognitive impairment severity
• Lower CBF was noted in the temporal and parietal lobes
• The precuneus exhibited significant reductions in blood flow
