Which of the following is NOT an example of psychosis associated with dementia?

The correct answer is schizophrenia because it is classified as a primary psychiatric disorder, distinct from the secondary psychotic symptoms that can arise in the context of dementia. In dementia-related psychosis, individuals may experience alterations in reality perception due to the neurodegenerative changes occurring in the brain, which affect cognitive function and behavior.

In contrast, schizophrenia is characterized by a spectrum of symptoms directly tied to the disorder itself, including hallucinations and delusions that are not a direct result of progressive changes in cognitive function due to dementia. Essentially, schizophrenia is considered an independent condition rather than a manifestation of cognitive decline or related disorders like Alzheimer's disease, Wernicke's syndrome, or organic brain syndrome. These conditions are associated with dementia and may lead to psychotic symptoms as a consequence of cognitive impairment.
