How does dementia-related psychosis differ from other types of psychosis?

  

Dementia-related psychosis (DRP) differs from primary psychotic disorders like schizophrenia in its cause, progression, and symptoms. DRP is secondary to neurodegenerative diseases such as Alzheimer’s or Lewy body dementia, emerging in mid-to-late life as cognitive decline worsens. Unlike primary psychosis, which follows a chronic course, DRP symptoms fluctuate and may be triggered by environmental changes, infections, or medications. It is linked to brain atrophy and amyloid plaques rather than neurotransmitter imbalances. DRP often coexists with agitation, aggression, or wandering, making management complex. Treatment prioritizes reducing distress and improving quality of life over long-term pharmacological interventions.
