The typical "Hollywood" representation of Schizophrenia involves vivid visual hallucinations.
However, in practice, the dozen or so people with a diagnosis of Schizophrenia I have worked with have only had auditory hallucinations. I can't tell if visual hallucinations are very uncommon, or if my selection size isn't large enough.
Are there any statistics showing what percentage of patients diagnosed with Schizophrenia have visual hallucinations, compared to aural hallucinations, or even no hallucinations at all?
