Pseudohallucination refers to hallucinatory images that are not sufficiently vivid and are produced in the patient’s subjective space such as in the brain or body. Hallucinations are not obtained through the sensory organs, but most often the patient’s mind is filled with talking voices, or the patient can see an image in his or her mind without using his or her own eyes. Although the hallucinated image is different from normal perception, the patient believes that he or she is hearing or seeing it. Because it is “heard”, pseudospeech hallucinations are generally classified as a perceptual disorder in psychopathology, but in fact, pseudospeech hallucinations should be classified as a thought disorder. The general characteristics of pseudospeech hallucinations are that the patient feels the sound of speech, this sound is not heard by the ear, because there is no role in the ear as a sense, but in the mind, the feeling of something is not a feeling but an appearance, the problem of appearance should belong to the category of thought disorders. The other two names for pseudo-verbal phantom hearing are: though thearing and thought chirping. Though thearing is when the patient experiences his or her thoughts as speech sounds that he or she and others can hear; it is most often seen in schizophrenia. Patients generally describe clearly that the voices they hear during pseudovisual hallucinations are not the voices of others. Most pseudo-verbal hallucinations occur after true verbal hallucinations, and the former may be a derivative of the latter. Patients with schizophrenia who have true verbal hallucinations in the basic early stages may develop pseudo-verbal hallucinations as the illness recurs. In fact, pseudoradic hallucinations, whether they are part of a perceptual disorder or a thought disorder, are positive symptoms and are treated with antipsychotic therapy. As for what the patient “hears” and how he reacts to what he “hears”, it is not meaningful to identify pseudophantomalous hallucinations. Many of the so-called pseudo-verbal hallucinations seen clinically in schizophrenia may be the expression of obsessive-compulsive ideas. Obsessiveidea, or compulsive thinking, refers to the recurrence of a concept or the same content in the patient’s mind, knowing that it is unnecessary, but unable to escape. Obsessive-compulsive thinking can manifest itself as certain thoughts that are repeatedly recalled (obsessive-compulsive recall), repeatedly thinking about meaningless problems (obsessive-compulsive exhaustion), always having some opposing thoughts in the mind (obsessive-compulsive oppositional thinking), and always doubting whether one is acting correctly (obsessive-compulsive doubt). Obsessive-compulsive thinking is often accompanied by obsessive-compulsive actions. Obsessive-compulsive symptoms are very common in the course of schizophrenia. In terms of the form of symptoms, obsessive-compulsive symptoms in schizophrenic patients can appear in the form of pseudophantomime. Many patients use words like “speech” and “voice” when describing this condition, which can easily lead the physician to believe that it is a perceptual disorder and the problem can be easily confused. For example, when a person with schizophrenia states, “I have talking voices in my head all the time. The doctor may ask, “Whose voice is it? A man or a woman? Do you recognize it? Is it commenting on you or ordering you around?” Such an inquiry is obviously designed to check for verbal hallucinations, and based on such an examination, we have difficulty detecting obsessive-compulsive ideas, which should be uncovered by paying attention to the patient’s feelings about the symptoms. If the patient is clearly anxious and feels torn about the symptoms, one should consider whether they are obsessive-compulsive symptoms. Many patients with schizophrenia are not clear about whether the emergence of obsessive-compulsive ideas is a thought or a voice, and some patients know that the emergence of a voice is a serious situation, while feeling tolerable about the distressing, nagging nature of the obsessive-compulsive ideas, and these ideas may prevent the patient from articulating the obsessive-compulsive symptoms. It is therefore very important to identify obsessive-compulsive symptoms from pseudo-verbal hallucinations, because the two are treated completely differently. Our perception of symptoms, as with the diagnosis of illness, tends to avoid the important, with verbal hallucinations being a psychotic symptom and obsessive-compulsive symptoms being a neurotic symptom. In clinical work, patients with schizophrenia who present with these symptoms are more likely to be considered pseudo-verbal hallucinations. The author believes that if these conditions occur, priority should be given to obsessive-compulsive symptoms because the diagnosis of schizophrenia has been established and finding pseudoradic hallucinations will not change the treatment, finding obsessive-compulsive symptoms will not. Obsessive-compulsive symptoms require antiobsessive-compulsive treatment and many antipsychotics can cause obsessions, and these drugs can be adjusted appropriately according to the situation.
