It is important not to assume that every person who hears voices or has a hallucination has schizophrenia or is taking drugs because sometimes the correct diagnosis or cause can be missed. Evaluating a person who has hallucinations involves careful history, mental status exam, lab work, brain imaging when indicated with CT or MRI, collateral from the family, CXR and urine toxicology.
Treatment of hallucinations includes treating the underlying cause and antipsychotics where needed. Contrary to popular belief, most types of hallucinations are usually reasonably easy to treat and respond fairly well to medication.
