Visual hallucinations are a well-documented and relatively common symptom in individuals with schizophrenia, affecting roughly a quarter to half of patients.

The analysis

The claim is specific and falsifiable, passing step 0. Papers [0] and [1] both provide robust evidence demonstrating that visual hallucinations are prevalent in a significant portion of individuals diagnosed with schizophrenia and related psychoses (ranging between 25% and 50%). Paper [3] is tangential as it focuses on auditory verbal hallucinations, and paper [2] is a case report about naltrexone. Therefore, the claim is supported.
