There is a review article on the use of acetylcholinesterase inhibitors for visual hallucinations in schizophrenia by Sachin Patel and colleagues and which is freely available here. This is a very short BMC Psychiatry paper. The authors justify their choice of topic thus:
‘The lifetime prevalence of visual hallucinations in patients with schizophrenia is thought to be more common than conventionally thought and estimates range from 24% to 72%’
The authors use simple search terms and although finding some papers on cognitive aspects of schizophrenia find no research papers examining their specific question. So they have a negative study. Simple question, simple results and effectively demonstrating why ‘negative studies’ are useful.
