Psychosis associated with Alzheimer's Disease

Psychosis associated with Alzheimer's disease is a severe neuropsychiatric complication affecting the central nervous system in patients diagnosed with Alzheimer's disease dementia Its occurrence marks an aggressive clinical trajectory linked to faster cognitive decline, heightened functional impairment, increased caregiver distress, and earlier institutionalization

It is clinically characterized by the emergence of persecutory delusions, misidentifications, and hallucinations—most commonly visual or auditory—that arise secondary to neurodegenerative pathology rather than primary psychiatric disorders

Pathophysiologically, it correlates with accelerated neurofibrillary tau tangle accumulation, extensive frontal and neocortical synaptic disruption, and altered regional cerebral blood flow and metabolism
