The distinction lies in the level of cognitive impairment typically observed in organic brain syndrome psychosis compared to functional psychotic disorders. Organic brain syndromes, such as those resulting from brain injury, infections, or substance abuse, often present with cognitive deficits and impaired reality testing, which can influence the nature of the hallucinations experienced. In these cases, hallucinations may stem from tangible neurological issues, leading to certain types or patterns of hallucinations that differ qualitatively from those seen in functional psychotic disorders.

On the other hand, functional psychotic disorders, like schizophrenia, often exhibit a range of hallucinations that can vary widely among individuals and are not necessarily tied to observable brain damage or dysfunction. The hallucinations here often reflect the underlying psychological processes or stressors rather than being a direct result of organic damage.

Therefore, the type of hallucinations helps differentiate between these two categories of psychotic disorders, highlighting how the underlying causes affect symptomatology.
