Disorders most frequently involved in the differential diagnosis of misophonia.
Disorder | Similarities with Misophonia | Differences with Misophonia | |
---|---|---|---|
Psychiatric disorder | Specific phobia | A triggering stimulus may evoke a negative response, as well as avoidance behaviors. | In specific phobia, one experiences mostly anxiety and fear, whereas with misophonia a high degree of anger and aggression is perceived [20]. |
Phonophobia | Fear of a specific sound. | The main symptom is not anxiety or fear as in phonophobia, but the feeling of irritation, disgust, or anger [10,20]. | |
Social phobia | Habitual avoidance of social situations, due to experiencing anxiety and stress. | In social phobia, the reason is a hypersensitivity towards negative social evaluation; whereas in misophonia, the social situation is avoided to prevent an encounter with the misophonic sound [20]. | |
Post-traumatic stress disorder (PTSD) | Aversive reaction to a stimulus and avoidance behaviors are shared. | The person with PTSD had to experience a traumatic event. In the case of misophonia, no such association has been demonstrated [20,35]. | |
Obsessive-compulsive disorder (OCD) | They share an excessive preoccupation towards a specific stimulus, as well as the feeling of anxiety. | People with OCD often perform compulsive behaviors to reduce anxiety. In their case, there are no behaviors such as aggression and anger that may occur in misophonia. | |
Intermittent explosive disorder | Here, the shared factor is anger. | In misophonia, the triggering stimulus of anger is always a sound, for explosive disorder it can be any stimulus. Loss of control does not usually occur in misophonia [20]. | |
Eating behavior disorders | The most frequent emotional trigger in misophonia, as in the TCA, is food. | For the person with misophonia, the trigger is the sound of food, for ED, it is the ingestion of food [23]. | |
Obsessive compulsive personality disorder (OCPD) | The shared factors are anger or aggression. | People with misophonia respond to the same auditory stimulus, people with OCPD do not relate to triggering sounds [20]. | |
Autism Spectrum Disorders (ASD) | Auditory hyper-reactivity is observed. | People with ASD show intolerance to unexpected and loud noises. People with misophonia can react to any type of auditory stimulus [20]. | |
Sensory processing disorder (SPD) | Auditory hyper-reactivity is observed. | The person with TPS reacts to unexpected and loud noises, there is also hyper-reactivity to other stimuli. The person with misophonia reacts to any auditory stimulus [20]. | |
Personality disorders with impulsive aggression | Difficulty in controlling anger and impulsivity occurs. | The reactions are not necessarily related to a specific sound, as is the case with misophonia [55]. | |
Auditive disorder | Tinnitus | Can provoke negative emotions; anxiety. | It is perceived in one or both ears in the absence of acoustic source [9]. |
Hyperacusis | Negative reaction to any auditory stimulus with physical characteristics (loudness and frequency) [55]. | The stimulus characteristics are neutral or of very low frequency and intensity and context-independent [3,56]. |
