Misophonia (or selective sound sensitivity syndrome) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues. These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses not seen in most other people. [8] Misophonia and the behaviors that people with misophonia often use to cope with it (such as avoidance of "triggering" situations or using hearing protection) can adversely affect the ability to achieve life goals, communicate effectively, and enjoy social situations. [4] [7] Originating within the field of audiology in 2001, [13] the condition remained largely undescribed in the clinical and research literature until 2013, when a group of psychiatrists at Amsterdam University Medical Center published a detailed misophonia case series and proposed the condition as a "new psychiatric disorder" with defined diagnostic criteria. [14] At present, misophonia is not listed as a diagnosable condition in the DSM-5-TR, ICD-11, or any similar manual, [8] [15] [16] [17] making it difficult for most people with the condition to receive official clinical diagnoses of misophonia or billable medical services. An international panel of misophonia experts has rigorously established a consensus definition of misophonia as a medical condition, [8] and since its initial publication in 2022, this definition has been widely adopted by clinicians and researchers studying the disorder. [18] [19]

When confronted with specific "trigger" stimuli, people with misophonia experience a range of negative emotions, most notably anger, extreme irritation, disgust, anxiety, and sometimes rage. [8] The emotional response is often accompanied by a range of physical symptoms (e.g., muscle tension, increased heart rate, and sweating) that may reflect activation of the fight-or-flight response. [8] Unlike the discomfort seen in hyperacusis, misophonic reactions do not seem to be elicited by the sound's loudness but rather by the trigger's specific pattern or meaning to the hearer. [20] [21] [22] Many people with misophonia cannot trigger themselves with self-produced sounds, or if such sounds do cause a misophonic reaction, it is substantially weaker than if another person produced the sound. [7] [8]

Misophonic reactions can be triggered by many different auditory, visual, and audiovisual stimuli, [8] most commonly mouth/nose/throat sounds (particularly those produced by chewing or eating/drinking), repetitive sounds produced by other people or objects, and sounds produced by animals. [7] [8] The term misokinesia has been proposed to refer specifically to misophonic reactions to visual stimuli, often repetitive movements made by others. [14] [23] Once a trigger stimulus is detected, people with misophonia may have difficulty distracting themselves from the stimulus and may experience suffering, distress, and/or impairment in social, occupational, or academic functioning. [8] Many people with misophonia are aware that their reactions to misophonic triggers are disproportionate to the circumstances, [8] and their inability to regulate their responses to triggers can lead to shame, guilt, isolation, and self-hatred, as well as worsening hypervigilance about triggers, anxiety, and depression. [24] [25] [26] Studies have shown that misophonia can cause problems in school, work, social life, and family. [18] In the United States, misophonia is not considered one of the 13 disabilities recognized under the Individuals with Disabilities Education Act (IDEA) as eligible for an individualized education plan, [27] but children with misophonia can be granted school-based disability accommodations under a 504 plan. [28]

The expression of misophonia symptoms varies, as does their severity, which can range from mild and sub-clinical to severe and highly disabling. [2] [8] The reported prevalence of clinically significant misophonia varies widely across studies due to the varied populations studied and methods used to determine whether a person meets diagnostic criteria for the condition. [29] But three studies that used probability-based sampling methods estimated that 4.6–12.8% of adults may have misophonia that rises to the level of clinical significance. [30] [31] [32] Misophonia symptoms are typically first observed in childhood or early adolescence, though the onset of the condition can be at any age. [7] [8] Treatment primarily consists of specialized cognitive-behavioral therapy, [11] with limited evidence to support any one therapy modality or protocol over another and some studies demonstrating partial or full remission of symptoms with this or other treatment, such as psychotropic medication. [12]

Terminology and origins of the concept

Pawel Jastreboff and Margaret M. Jastreboff coined the term "misophonia" in 2001 with the assistance of Guy Lee, [33] [34] introducing it in their article "Hyperacusis", [35] with further explanation in the International Tinnitus and Hyperacusis Society's ITHS Newsletter. [13]

"Misophonia" comes from the Ancient Greek words μῖσος (IPA: /mîː.sos/), meaning "hate", and φωνή (IPA: /pʰɔː.nɛ̌ː/), meaning "voice" or "sound", loosely translating to "hate of sound", and was coined to differentiate the condition from other forms of decreased sound tolerance, such as hyperacusis (hypersensitivity to certain frequencies and volume ranges) and phonophobia (fear of sounds). [6] [36] [13]

The term "misophonia" was first used in a peer-reviewed journal in 2002. [37] Before that, the disorder was more commonly called "selective sound sensitivity syndrome", or "4S", a term coined by audiologist Marsha Johnson. [18] Other names formerly used for the condition include "soft sound sensitivity symptom", "select sound sensitivity syndrome", "decreased sound tolerance", and "sound-rage". [4]

In their seminal 2013 case series of patients with misophonia, Schröder and colleagues coined the term "misokinesia" (a term analogous to misophonia translating to "hatred of movement") [14] to describe misophonia-like reactions that occur when people are "triggered" by specific repetitive visual stimuli, such as another person's foot shaking, fingers tapping, or gum chewing. [23] Other authors have proposed "Conditioned Aversive Response Disorder" (C.A.R.D.) as a more suitable name, which seeks to incorporate both auditory and non-auditory aspects of misophonia/misokinesia into a single condition. [38]

Adopting DSM-5-like terminology, some research groups have also advocated the term "misophonic disorder" [2] to distinguish clinically significant and disabling misophonia from what they term "misophonic reactions" (i.e., sub-clinical manifestations of misophonia that do not cause marked distress or substantially impair a person's daily life, relationships, or activities). [2]

Notably, of the above terms, only "misophonia" is widely used by researchers, clinicians, and sufferers of the condition. It is the primary term used for the condition in mainstream journalistic coverage [39] [40] [41] [42] and by the primary philanthropic agency funding research into it (The Misophonia Research Fund [MRF]), [43] and the term selected for use in an (MRF-funded) project to derive a field-wide consensus definition of the condition for clinical and research use. [8]

Signs and symptoms

Misophonia is a disorder of sound tolerance characterized by extreme and disproportionate emotional reactions to specific sounds (or less commonly, visual stimuli) in one's environment, termed "triggers." [8] Trigger stimuli are experienced as extremely unpleasant or distressing and tend to evoke a "misophonic reaction" that consists of both unpleasant negative emotions (i.e., extreme irritation, anger, anxiety, or disgust; less commonly rage or panic) and increased sympathetic arousal (manifested in physical symptoms such as muscle tension, increased heart rate, and sweating). [7] [8]

Trigger stimuli are highly varied and sometimes idiosyncratic, but certain stimuli such as chewing and other oronasal sounds are among the most commonly reported triggers in both clinically referred and population-based samples. [7] [8] The Duke Misophonia Questionnaire, [44] a commonly used misophonia symptom measure, groups misophonia triggers into the following categories:

Although less well studied, reported visual triggers in misokinesia include another person's repetitive movements (foot/leg shaking, arms swinging, hands rubbing together, hair twirling, fidgeting), as well as the sight of an auditory trigger that one cannot actually hear (such as someone chewing with their mouth open or tapping their fingers on a desk). [7] [8] [23]

Reactions to triggers can range from mild (extreme irritation, anxiety, disgust, and/or physical discomfort) to severe (anger, rage, hatred, fear, panic, and/or profound emotional distress). [8] A number of physical symptoms may also accompany the misophonic response, including muscle tension, increased heart rate, sweating, and a feeling of pressure in one's body. [7] [8] [18] Other idiosyncratic physical and cognitive symptoms are also possible. [7] [18]

The five dimensions of cognitive-behavioral responses to "triggers", as empirically derived from the "S-Five" (another misophonia questionnaire that was used in the first large-scale prevalence study of the condition in the UK), [45] [46] [47] are as follows:

People with misophonia, particularly adults, are typically aware that their emotional reactions and behaviors in response to triggers are disproportionate to the situation, [18] and this frequently causes some degree of internal conflict due to a desire to suppress these reactions. [24]

The first misophonic reaction typically occurs when a person is young, often between the ages of 9 and 13. [7] But misophonia can have an onset at any age, with cases as young as two years old and a number of adult-onset cases reported in the literature. [18] [7] The initial misophonic reaction will often originate from someone in a close relationship or a pet. [48]

Fear and anxiety associated with trigger sounds can cause people with this condition to avoid important social and other interactions that may expose them to these sounds. [7] This avoidance and other behaviors can make it harder for them to achieve their goals and enjoy interpersonal interactions. [6] [26] It can also have a significant adverse effect on their careers and relationships. [18] Many people with misophonia experience worsening mental health, and some develop psychopathology secondary to their misophonia, including depression, anxiety, phonophobia, self-harm behaviors, and suicidality. [18] [26] [49] [50]

Mechanism

Misophonia's mechanism is not yet fully understood, and all proposed causes of the disorder are hypothesized based on a combination of clinical observation and the limited existing empirical research. [4] Although misophonia is a disorder of sound tolerance, work to date has not typically demonstrated any peripheral audiologic abnormalities in people with the condition, [51] [52] [53] suggesting that any "auditory" abnormalities may be caused by a dysfunction of the central auditory system or other parts of the brain that govern "higher-order" perceptor or cognition, rather than the ears per se. [17]

Some research has found evidence consistent with the idea that there are genetic contributions to misophonia, but more research is needed. [54] An unpublished study suggests a genetic locus is associated with responses to a single question asking about the misophonic symptom of experiencing rage to sounds of people chewing. [55]

"Neurophysiological" (Jastreboff) model

The first mechanistic theory of misophonia, proposed by Jastreboff and Jastreboff in 2014, [56] [57] is based on the authors' clinical experience and little empirical data. This model, which the authors call the "neurophysiological model", [57] seeks to contrast misophonia with hyperacusis, another disorder of sound tolerance that primarily manifests as excessive loudness perception (or the experience of physical pain in one's ears or head) in response to soft or moderate-intensity everyday sounds. [19] [58] The Jastreboffs' neurophysiological model posits that the fundamental difference between misophonia and hyperacusis is that decreased sound tolerance in hyperacusis is closely coupled to the physical properties of the sound stimulus (i.e., intensity, frequency) while, in misophonia, decreased tolerance of "trigger" sounds has little to do with acoustic properties (beyond louder sounds perhaps being easier to perceive and respond to) [57] and arguably depends almost exclusively on the meaning of the sound(s) to a given person. [56] [57] [59] Its creators have used this model to explain certain aspects of the misophonia phenotype, such as that most people with misophonia do not present with peripheral hearing loss and that context (including whether a trigger is produced by oneself) plays a large role in response to a trigger sound. [57] [59]

Although entirely speculative and not based on any empirical neuroscientific data on misophonia, the "neurophysiologic" model also postulates several putative neural mechanisms for the condition from a systems neuroscience perspective. [59] Namely, when processing a trigger stimulus, the brain's central auditory system is thought to have enhanced functional connections with its limbic and autonomic control areas, and downstream overactivity of these areas is theorized to be responsible for the excessive emotional responses and certain physical symptoms of the condition, respectively. [57] These preliminary neuroscientific hypotheses form the basis of the Jastreboffs' signature intervention for sound tolerance conditions (Tinnitus Retraining Therapy, an unproven combination of structured counseling and sound therapy originally developed for tinnitus and now available in modified form to treat misophonia). [56] [59]

Notably, there has been relatively little empirical support for the central neuroscientific hypotheses of the neurophysiologic model. Although there has been a relative lack of neuroimaging research on misophonia thus far, functional connectivity between auditory cortical and limbic or autonomic control areas is not typically increased either at rest or during the experience of trigger sound perception. [9] Though many of these same limbic and autonomic control areas may still be relevant in the pathophysiology of misophonia (with anterior insula being one of the most strongly implicated nodes thus far), [9] recent reviews of human neuroimaging research in this condition [9] [60] indicate that (a) their activation may be driven by other pathways than simple auditory→limbic or auditory→limbic→autonomic hyper-connectivity and (b) additional structures outside of the Jastreboffs' model (such as premotor cortex) [61] may play a central role in this disorder. The "neurophysiologic" model has also been criticized by other theorists for its vagueness and unwillingness to specify the specific neural structures/processes involved in the "limbic system" portion of the model, as well as its inability to account for non-sound trigger stimuli.

"Action perception" (Berger-Gander-Kumar) model

A more recently developed model of misophonia was published by neuroscientist Sukhbinder Kumar and colleagues at the University of Iowa in 2024. [60] This model, not formally named by the authors but termed the "action perception" model of misophonia by other researchers using it [62] (alternatively the Berger-Gander-Kumar model), sought to build on the perceived shortcomings of earlier models [56] [3] by explicitly incorporating more up-to-date empirical findings in the behavioral, clinical and neuroimaging literature on misophonia; providing explanations for the presence of non-auditory (i.e., visual) and multi-sensory trigger stimuli; and considering perspectives from social cognitive theory and social neuroscience in the broader theory. Although the action perception model is consistent with many of the findings in the misophonia neuroimaging literature, it is important to note that it was generated specifically to explain those findings and therefore represents something of a "just-so story" until its predictions can be empirically validated. [60] [63] [64]

Based on what is known from neuroimaging and behavioral studies of misophonia, the action perception model conceptualizes the disorder as follows: [60]

The action perception model arguably represents a major advance over previous theoretical work in this area, particularly in its ability to explain the neuroimaging data on misophonia published before 2024, when the theory was first proposed. [60] Additionally, by focusing on higher-order "motor representations" of objects/actions that are abstracted from their initial sensory information and represented in association cortex (i.e., motor/premotor and limbic areas), the model can be applied to both the auditory and non-auditory triggers of misophonia (i.e., misokinesia) just as easily. [60] But the action perception model appears to apply only to misophonic reactions to human-generated trigger sounds. [38] The action perception model appears consistent with certain clinical features of misophonia, such as the extreme context-specificity of the condition, given that the perceived (even if incorrectly perceived) source of the sound [66] and whether the source can be identified [67] appear to be among the largest drivers of the severity of a given misophonic reaction. [60] Last, although still largely speculative, the action perception model provides an explanation for the peculiar observation that many people with misophonia (46.7% of this population in a recent study by Kumar's group) [68] engage in mimicry (deliberate or unconscious imitation of the trigger sound). As the anterior insula is engaged when counter-imitating an action (i.e., performing the opposite of the imitated movement), [69] Kumar and colleagues theorize that this mimicry conveys an "error signal" that helps inhibit the hyperactive insular cortex involved in the triggering process, thereby reducing the intensity of the misophonic response. [60] [68]

Despite its apparent success in explaining findings in the misophonia literature, the action perception model's predictions are largely untested, and many aspects of the model rely on empirical studies with substantial methodological limitations. [60] The basic neural mechanisms of action perception, mimicry, and the role (if any) of the "human mirror neuron system" within a broader social cognition framework in non-clinical populations must be further explored. [60] The role of other co-occurring conditions, particularly those such as autism that are known to both affect social cognition and cooccur with misophonia at exceptionally high rates, [62] [70] is also an area for future research to explore and test the model. [60] The evidence supporting the action perception model is essentially correlational, not causal; [38] that is, it is unclear whether motor representations cause misophonic reactions or misophonia is a primarily auditory experience sometimes accompanied by motor representations.

Diagnosis and assessment

In 2022, clinical and scientific leaders convened to create a consensus definition of misophonia, [8] agreeing that it is a disorder of decreased tolerance to specific sounds and their associated stimuli. During the early phase of research on misophonia, it was defined by different criteria, and different methods were used to diagnose it and assess symptom severity. As a result of lack of consensus about how to define and evaluate misophonia, comparisons between study cohorts were difficult, measurement tools were not psychometrically well-validated, and the field could not rigorously assess the efficacy of different treatment approaches. [8] The consensus definition is still not universally accepted by misophonia experts. [57]

Despite some early proposals, [14] [71] there is no scholarly consensus about diagnostic criteria or assessment procedures for misophonia. [8] [15] Many doctors are unaware of the disorder. [8]

It appears that misophonia can occur on its own or with other health, developmental, and psychiatric problems. [8] These comorbid conditions include anxiety disorders, post-traumatic stress disorder, [72] OCD, [73] [74] [75] and depressive disorders. [76] [77] Misophonia is distinguishable from hyperacusis, which is not specific to a given sound and need not involve a similarly strong emotional reaction, and from phonophobia, the fear of sounds, [48] but it may occur with either. [78] When attempting to diagnose a patient with misophonia, doctors sometimes mistake its symptoms for an anxiety disorder, bipolar disorder, obsessive-compulsive disorder, or obsessive-compulsive personality disorder. [8] [79] [80] [81] [82] [83]

Due in part to the need for differential diagnosis with other psychiatric and audiological conditions, academic commentaries make various recommendations regarding misophonia assessment, including that misophonia diagnoses be made by multidisciplinary groups and draw upon multiple sources of data. [18] [19] [84]

Classification

The diagnosis of misophonia is not recognized in the DSM-5-TR or the ICD-11 and it is not classified as a hearing or psychiatric disorder. [48]

The consensus of misophonia experts is that the relationship between misophonia and other conditions is not yet clear. [8] Scholars debate whether misophonia should be considered an audiological or psychiatric disorder, with some evidence favoring the latter view. [14] [16] It has been tentatively suggested that misophonia belongs to the spectrum of obsessive-compulsive-and-related disorders, although the authors of this proposal also describe it as "premature". [14]

Measures

Misophonia has generally been measured using adult self-report questionnaires. [85] A 2021 review of misophonia and hyperacusis measures found only three misophonia instruments with reported psychometric properties, all of which were adult self-report measures; the review called the evidence regarding the measures' psychometrics "limited". [85] Psychometric properties of a number of additional adult self-report misophonia measures have since been reported in the scholarly literature. [44] [45] [86] [87] [88] [89] [90] Further unvalidated misophonia questionnaires are available on the internet. [18] [19] [91]

More recently, self-report and caregiver proxy-report measures intended to measure misophonia in children and youth have begun to appear in the scholarly literature. [92] [93] [94] At least one study uses interviews with caregivers, and sometimes their children, to assess misophonia in children and adolescents. [95]

Another relatively novel development in misophonia assessment is a psychoacoustic measure, which uses adults' self-reported ratings of the pleasantness of sounds to identify a set of sounds that appear to distinguish between people with and without misophonia. [96]

Due to the difficulty of distinguishing misophonia from other psychiatric and audiological conditions, it is unclear whether any single tool can be relied upon to diagnose misophonia. [18] [84] It has been suggested that assessment should involve collection of multiple sources of data, such as patient case histories, interviews, audiological examination, and self-report tools. [18] [19] [84]

Management

Health care providers generally try to help people cope with misophonia by recognizing what the person is experiencing and working on coping strategies. [48] A majority of smaller studies done on the subject have focused on the use of tinnitus retraining therapy, cognitive behavioral therapy and exposure therapy, which is believed to decrease the person's awareness of their trigger sounds. [6] These treatment approaches have not been sufficiently studied to determine their effectiveness. [6] [36] Other possible treatment options have been theorized by researchers, including acceptance-based approaches and mindfulness. [6] Ultimately, it is speculated that treatment methods may vary significantly in effectiveness from patient to patient. [6]

Minimal research has been conducted on the possible effects of neuromodulation and pharmacologic treatments. A study published in 2022 suggests that some forms of misophonia treatment may vary in effectiveness based on the preference of each patient, particularly in cases of parents with children who have misophonia. [97] In addition, the use of propranolol has also been found to be helpful in some patients. [98]

Clomipramine has anecdotally been found to be of use in at least a certain subset of people suffering from disorders allied with hyperacusis; [99] given its success in the treatment of obsessive-compulsive disorder, it may have a place in the treatment of misophonia, [100] which appears to have parallels with both conditions. Clomipramine does appear to have a distinct potential mediating effect on auditory-tone processing. [101] [102] One specific phenomenon observed to this end with clomipramine in at least one instance is reduced electrodermal reactivity to innocuous auditory stimuli. [102]

Whether pindolol (a beta-blocker with similar action to propranolol and augmentative therapeutic effects in obsessive-compulsive disorder [103] ) and certain selective serotonin reuptake inhibitors (e.g., fluvoxamine, escitalopram, fluoxetine) can also prove effective in the treatment of misophonia likewise remains to be seen.

Large-scale research has not yet been conducted, but observation of coping strategies people with misophonia use has shown some consistent results. [6] People with misophonia often cope by avoiding distressing situations or distracting themselves from such situations, [104] for example by using earplugs or headphones, mimicking trigger sounds, and playing music. [105]

Sequent repatterning therapy

Sequent Repatterning therapy for misophonia (SRT) is based on the idea that emotional responses are learned and consolidated over time, rather than innate, which makes it a form of cognitive behavioral therapy. [106] Development of this therapy began in 2012 when researcher Christopher Pearson applied aspects of hypnotherapy, parts work therapy, and NLP to create a therapy model for misophonia. He presented his work to the International Association of Neuropsychotherapy in 2017 and an article, "Reviewing Misophonia and its Treatment", [107] was published in International Journal of Neuropsychotherapy later that year. Pearson also contributed to the proposals for diagnostic criteria for misophonia, published in Frontiers. [71] Sequent Repatterning practitioners apply these diagnostic steps when assessing potential clients. Sequent Repatterning Therapy is not generally accepted by the clinical community and has not been shown to be an effective therapy for misophonia, which has not been shown to be caused by habituation. Habituation-based therapies often exacerbate symptoms instead of easing them.

Epidemiology

Research is still being conducted on misophonia's global prevalence, but a 2023 study found its prevalence in the UK to be around 18%. [47] This study has been cited in popular outlets, including BBC, [108] Medscape, [109] and Medical Xpress. [110] Studies of misophonia's global prevalence have found it to be as low as 5% and as high as 20%. [47] Its prevalence and severity seem to be similar across genders. [47] In the U.S., it is estimated that 3% of people are affected by misophonia. But in multiple studies, it was determined misophonia may be underdiagnosed (it is not yet an officially diagnosable condition), as it is correlated with other auditory disruptions; 92% of patients who are hyperaware of sounds also have misophonia. [18] There is evidence that significant numbers of undergraduate students in some psychology and medical-science departments suffer from misophonia. [111] The University of Nottingham conducted a study of misophonia in one sample of undergraduate medical students. [87] In 2017, similar rates were found in one university in China, [112] suggesting that the disorder is not specific to a culture.

It may be the case that people with misophonia are more likely to have high fluid intelligence. [113]

Associated symptoms

Some people [114] have sought to relate misophonia to autonomous sensory meridian response, or auto-sensory meridian response (ASMR), a pleasant form of paresthesia, a tingling sensation that typically begins on the scalp and moves down the back of the neck and upper spine. [115] ASMR is described as the opposite of what can be observed in reactions to specific audio stimuli in misophonia. [116] There are plentiful anecdotal reports of people who claim to have both misophonia and ASMR. Common to these reports is the experience of ASMR in response to some sounds and misophonia in response to others. [116] [117] [118]

Society and culture

People who experience misophonia have formed online support groups. [119] [14] [120]

In 2016, a documentary about the condition, Quiet Please, was released. [121]

In 2020, a team of misophonia researchers [14] received the Ig Nobel Prize in medicine "for diagnosing a long-unrecognized medical condition". [122]

The 2022 film Tár depicts a conductor with misophonia. [123]

Season 1, episode 4 of Hulu's The Old Man has a brief discussion of misophonia. [124]

Tinnitus is a condition when a person hears a ringing sound or a different variety of sound when no corresponding external sound is present and other people cannot hear it. Nearly everyone experiences faint "normal tinnitus" in a completely quiet room; but this is of concern only if it is bothersome, interferes with normal hearing, or is associated with other problems. The word tinnitus comes from the Latin tinnire, "to ring". In some people, it interferes with concentration, and can be associated with anxiety and depression.

Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) is a controversial hypothetical diagnosis for a subset of children with rapid onset of obsessive-compulsive disorder (OCD) or tic disorders. Symptoms are proposed to be caused by group A streptococcal (GAS), and more specifically, group A beta-hemolytic streptococcal (GABHS) infections. OCD and tic disorders are hypothesized to arise in a subset of children as a result of a post-streptococcal autoimmune process. The proposed link between infection and these disorders is that an autoimmune reaction to infection produces antibodies that interfere with basal ganglia function, causing symptom exacerbations, and this autoimmune response results in a broad range of neuropsychiatric symptoms.

An addictive behavior is a behavior, or a stimulus related to a behavior, that is both rewarding and reinforcing, and is associated with the development of an addiction. There are two main forms of addiction: substance use disorders and behavioral addiction. The parallels and distinctions between behavioral addictions and other compulsive behavior disorders like bulimia nervosa and obsessive-compulsive disorder (OCD) are still being researched by behavioral scientists.

The obsessive–compulsive spectrum is a model of medical classification where various psychiatric, neurological and/or medical conditions are described as existing on a spectrum of conditions related to obsessive–compulsive disorder (OCD). "The disorders are thought to lie on a spectrum from impulsive to compulsive where impulsivity is said to persist due to deficits in the ability to inhibit repetitive behavior with known negative consequences, while compulsivity persists as a consequence of deficits in recognizing completion of tasks." OCD is a mental disorder characterized by obsessions and/or compulsions. An obsession is defined as "a recurring thought, image, or urge that the individual cannot control". Compulsion can be described as a "ritualistic behavior that the person feels compelled to perform". The model suggests that many conditions overlap with OCD in symptomatic profile, demographics, family history, neurobiology, comorbidity, clinical course and response to various pharmacotherapies. Conditions described as being on the spectrum are sometimes referred to as obsessive–compulsive spectrum disorders.

Exposure therapy is a technique in behavior therapy to treat anxiety disorders. Exposure therapy involves exposing the patient to the anxiety source or its context. Doing so is thought to help them overcome their anxiety or distress. Numerous studies have demonstrated its effectiveness in the treatment of disorders such as generalized anxiety disorder (GAD), social anxiety disorder (SAD), obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and specific phobias.

Obsessive–compulsive disorder (OCD) is a mental and behavioral disorder in which an individual has intrusive thoughts and feels the need to perform certain routines (compulsions) repeatedly to relieve the distress caused by the obsession, to the extent where it impairs general function.

The biology of obsessive–compulsive disorder (OCD) refers to biologically based theories about the mechanism of OCD. Cognitive models generally fall into the category of executive dysfunction or modulatory control. Neuroanatomically, functional and structural neuroimaging studies implicate the prefrontal cortex (PFC), basal ganglia (BG), insula, and posterior cingulate cortex (PCC). Genetic and neurochemical studies implicate glutamate and monoamine neurotransmitters, especially serotonin and dopamine.

In psychology, relationship obsessive–compulsive disorder (ROCD) is a form of obsessive–compulsive disorder focusing on close intimate relationships. Such obsessions can become extremely distressing and debilitating, having negative impacts on relationships functioning.

Musical hallucinations describes a neurological disorder in which the patient will hallucinate songs, tunes, instruments and melodies. These hallucinations are not correlated with psychotic illness. A majority of patients who have symptoms of musical hallucinations are older and have onset conditions predisposing them to the disease. While there is no set form of treatment, research has discovered medications and alternative therapies to be successful in alleviating the hallucinations.

Arthur Guy Lee, known informally as Guy Lee, was a British Classical scholar and poet. He was particularly notable as a Latinist for his work on the Roman poets Ovid, Propertius, and Catullus; he also translated Virgil's Eclogues, Tibullus, and Persius.
