Schizophrenia
Therapies include counselling, but also cognitive-behavioral therapy, or CBT. In CBT, the person talks to a professional who helps the person recognise that some of their strange thoughts are not real. These strange thoughts are usually called delusions. The therapist can also design an experiments for paranoia, a false fear of danger. This can help the people find out, for example, if there are cameras everywhere in the house. For hallucinations, cognitive therapy focuses on normalizing: many people hear voices without being stressed, and we all hear voices in the form of thoughts, it is just that people with schizophrenia hear them a bit more clearly than most people.
