It is particularly important to seek medical care if someone with an illness that may cause hallucinations experiences worsening hallucinations or other changes in mood or behavior. Not all hallucinations require treatment, especially if the hallucination is a singular event.
A hallucination is not a medical emergency, but only a doctor can determine whether it signals a serious health issue. Hallucinations are more common than many people might realize. Although they can be frightening, they do not always mean a person has a serious brain disorder or mental health issue.
People with hallucinations and those who love them should track symptoms to measure when the hallucinations happen and whether anything seems to trigger them. This record-keeping can help a doctor better treat their symptoms. Bipolar disorder and schizophrenia have some similarities, but there are key differences.

What are hypnagogic hallucinations? What are tactile hallucinations? Auditory hallucinations have been reported in patients with both bilateral and unilateral hearing loss.
It has also been reported in patients who have been bilaterally deaf since birth. The form ranges from irregular sound, instrumental music, songs to full-form voices. Unilateral auditory hallucination is mostly associated with ipsilateral hearing loss. In the above-mentioned cases, the majority did not have any psychiatric or organic condition that may account for these hallucinations. The theory of hallucinations secondary to chronic sensory deprivations seems to support the above findings.
Visual hallucinations have been reported in patients with impaired vision or blindness since birth. When visual hallucinations follow marked visual acuity loss, in the absence of cognitive impairment, the condition is termed Charles Bonnet Syndrome, with an estimated prevalence of 0. The phenomenology of the visual hallucinations does not appear to correlate with the underlying ocular disease, although significant bilateral loss in visual acuity appears to be a primary trigger.
In , Charles Bonnet described vivid visual hallucinations in his psychologically normal visually impaired grandfather. Triggers of the syndrome include fatigue, low levels of illumination, bright lighting and stress as with this patient. Once manifested, the images may last for periods varying from seconds to minutes to hours. Although the most commonly associated ocular pathology is age-related macular degeneration, the syndrome has been associated with cataracts, glaucoma, diabetic retinopathy and retinitis pigmentosa as in this patient.
It has also been described in cerebral disorder and as a side-effect of medication. Patients with Charles bonnet syndrome CBS must have formed complex persistent or repetitive visual hallucinations, full or partial retention of insight awareness of the unreal nature of the hallucination , absence of delusions and absence of auditory or other sensory hallucinations. Single photon emission computed tomography SPECT studies in patients with CBS disclosed hyperperfusion areas with some asymmetrical appearances in the lateral temporal cortex, striatum and thalamus.
This suggests that decreased visual acuity due to eye disease produces excessive cortical compensation in the lateral temporal cortex, striatum and thalamus, which may precipitate the development of visual hallucinations. Compared with the rich phenomenological data that we have on hallucinations, its diagnostic significance is limited. Auditory hallucinations of thought echo, discussing type in 3 rd person and running commentary type all form part of Schneider's first rank symptoms form the basis of diagnosing schizophrenia according to ICD Cenesthetic hallucinations can be diagnostic of a special variety of rare schizophrenia.
Alcohol-related hallucinations can phenomenologically differentiate delirium tremens from alcoholic hallucinosis, but it is very difficult to delineate the latter from schizophrenia. Auditory hallucinations are most common in all groups except organic brain syndromes, where visual hallucinations predominate. In spite of the above-mentioned facts, a patient presenting with hallucinations as one of his symptoms needs complete psychiatric and neurological diagnostic evaluations to reach at the correct diagnosis.
Clinically, eliciting hallucinations and analyzing it in detail may be of prognostic and academic importance but, for diagnosis, one must get a holistic account of the patient. Some children or adolescents may report of subclinical hallucination or delusion, yet not fulfill the criteria for specific psychotic disorders [ Table 2 ]. They are not severe or frequent enough to warrant clinical diagnosis of psychotic disorder.
Three hypotheses in the current literature propose that these symptoms are:. The relationship between childhood trauma and auditory hallucination is not limited to subjects with dissociative disorders, but is also found in the general population and in schizophrenic patients. Kessler[ 9 ] screened first-admission psychotic patients and reported that 18 5.
He suggested that isolated early childhood hallucination may confer increased risk for adult psychosis. It is, however, unclear as to what percent of cases of isolated early childhood hallucination develops into major psychosis later in life. Hallucinations in the general population are associated with victimization experiences, average and below average IQ and female sex. A multitude of circumstances can trigger hallucinations in normal persons as well as clinical populations.
These include deprivation food, sensory, sleep , fatigue, during going into or waking up from sleep, sleep-related states, life-threatening states, bereavement, grief reaction, prolonged perceptual isolation, sexual abuse, religious ritual activities and trance states. Subjects may report hallucinations in conditions of increased external stimulation e. It is common for people especially older people to see, hear or feel the presence of the deceased person during bereavement.
Hallucination as part of functional or organic psychosis responds best to antipsychotics. All antipsychotics are effective, the newer antipsychotics having an edge over the traditional antipsychotics.
General guidelines for pharmacotherapy of psychosis apply for hallucination as well. Even with the advent of newer antipsychotics, a significant minority of patients continue to hallucinate.
Studies clearly establishing the efficacy of rTMS for the treatment of hallucinations are lacking. A recent metaanalysis concluded that low-frequency rTMS over the left temporoparietal cortex has a moderate effect size for the treatment of medication-resistant Auditory Hallucinations AH. Self-initiated self-coping is common in psychosis, indicating that individuals who feel overwhelmed by their psychotic experiences mobilize coping defenses. The coping strategies identified in a few studies are summarized in Table 3.
For patients, caregivers and their associates, psychoeducation is a valuable tool for determining what is wrong with the patient and how the condition may have developed. This is especially true for a stigmatizing illness such as schizophrenia and for stigmatizing experiences such as hallucinations. On an individual level, distress associated with hallucinations is alleviated by medications and psychotherapy.
However, distress associated with hallucinations may also be decreased on a societal level. That is, if attitudes in the general population concerning hallucinations were less negative and damaging, then this would make it much easier for those suffering from hallucinations to properly manage their experiences. Therefore, education campaigns concerning psychotic experiences geared toward the general public, schools and primary health service are also an important intervention strategy.
Brief educational courses in mental illness reduce stigmatizing attitudes among a wide variety of participants. The aims of Cognitive behavior therapy CBT for psychotic patients are to reduce the distress and disability caused by psychotic symptoms, to reduce emotional disturbances and to help the person to arrive at an understanding of psychosis, to promote the active participation of the individual in the regulation of risk of relapse and social disability.
Garety et al ,[ 42 ] conceptualized CBT as a series of six stages: 1 building and maintaining a therapeutic relationship, 2 using cognitive-behavior coping strategies, 3 developing a new understanding of the experience of psychosis, 4 addressing delusions and hallucinations, 5 addressing negative self-evaluations, anxiety and depression and 6 managing the risk of relapse and social disability. According to this formulation, a voice is seen as an activating event A to which the individual gives a meaning B and experiences the associated emotional and behavioral reactions C.
This, the distress and coping behavior, are consequences not of the hallucination itself but of the individual's belief about hallucination. Table 4 gives two examples of ABC analysis of auditory hallucinations, one for a voice believed to be benevolent and one malevolent. Studies suggest that CBT is a modestly effective treatment scheme for positive psychotic symptoms, although there have been negative findings in well-conducted studies.
However, few studies have specifically examined the positive effect of CBT on hallucinations, although Valmaggia et al. One general limit of CBT is that it does not deal with the hallucinations themselves but deals exclusively with reactions e. Lynch et al. Trials of effectiveness against relapse were also pooled, including those that compared CBT with treatment as usual. Blinding was examined as a moderating factor.
They concluded that CBT is no better than non-specific control interventions in the treatment of schizophrenia and that it does not reduce the relapse rates. CBT was effective in reducing symptoms in major depression, although the effect size was small, and in reducing relapse.
CBT was ineffective in reducing relapse in bipolar disorder. Hallucination-focused integrative treatment HIT uses multiple modalities to maximize control of persistent auditory hallucinations. It integrates a number of different types of treatment strategies CBT, supportive psychotherapy, psychoeducation, coping training, mobile crisis intervention and antipsychotic medication.
The intervention uses 20 one-hour sessions over 9—12 months. HIT is different from most CBT programmes in that both patient and relatives receive cognitive interventions and coping training. Studies suggest that HIT is effective for chronic schizophrenia patients and for psychotic adolescents with auditory hallucinations. Also, these positive effects last as long as 9—18 months after treatment.
Auditory hallucinations are subjective experiences that are difficult to measure objectively. The advent of effective pharmacological treatment might have hampered research on various psychological treatments of auditory hallucination, which has prevented the characterization of any putative good response group.
There is insufficient evidence to favor any particular psychological treatment over any other. All the above techniques show a benefit in some patients. This suggests that rather than abandoning psychological therapies, treatment should be individually tailored and used as an adjunct to pharmacotherapy. Hallucination is a fundamental symptom in psychiatry. Two hundred years of research into this phenomenon has not yet answered the following questions:.
Whether the presence of hallucinations as such or in different modalities and forms can include or exclude certain diagnoses or not? These questions are very basic to the understanding of mental diseases and more research in both the phenomenological and the theoretical areas is necessary to unfathom the secret. Conventionally, hallucinations are treated as psychotic features. However, there is ample evidence to support hallucination in non-psychotic conditions.
The mechanism and nosological status of these conditions are not yet clear. Assessing the cultural background in the evaluation of hallucination is important as the concept of reality varies across cultures and there is a possibility of culturally sanctioned hallucination. Apart from effective pharmacological treatment, a greater awareness is needed regarding the psychological treatment of hallucination, which can help us deal with refractory hallucinations.
Source of Support: Nil. Conflict of Interest: None declared. The recommended treatment options for hallucinations will depend on the underlying cause. For example, antipsychotic medication may help with hallucinations for people living with schizophrenia.
Hallucinations can make you feel nervous, paranoid and frightened, so it's important to be with someone you can trust. The following information explains the typical types of hallucinations, including why they occur and what you can do.
Hallucinations can also occur as a result of extreme tiredness or recent bereavement. However, these and other rarer causes are not covered here. Hearing voices in the mind is the most common type of hallucination in people with mental health conditions such as schizophrenia. The voices can be critical, complimentary or neutral, and may make potentially harmful commands or engage the person in conversation. They may give a running commentary on the person's actions. The experience is usually very distressing, but it's not always negative.
Some people who hear voices are able to live with them and get used to them, or may consider them a part of their life. It's not uncommon for recently bereaved people to hear voices, and this may sometimes be the voice of their loved one. If you're hearing voices, discuss any concerns you have with your GP.
If necessary, they'll refer you to a psychiatrist. This is important in determining whether you have a serious mental illness. If your voices are due to schizophrenia, the earlier your treatment is started, the better the outcome. The Mental Health Foundation has more information and practical advice about how to deal with hearing voices.
People can experience hallucinations when they're high on illegal drugs such as amphetamines, cocaine, LSD or ecstasy. They can also occur during withdrawal from alcohol or drugs if you suddenly stop taking them. Drug-induced hallucinations are usually visual, but they may affect other senses. They can include flashes of light or abstract shapes, or they may take the form of an animal or person.
More often, visual distortions occur that alter the person's perception of the world around them. The hallucinations can occur on their own or as a part of drug-induced psychosis.
