Introduction & Orientation
■ Individuals with misophonia, their families, and friends
■ Clinicians across disciplines (i.e., audiologists, psychologists,
psychiatrists, LPC’s, RN’s, occupational therapists, etc.)
■ Teachers and those in the school systems who may work with
misophonic individuals and their families
■ Goal: Overview of misophonia research, treatment and coping
skills

What is Misophonia?1, 2, 3
■ Misophonia is a recently termed auditory and neurological syndrome

Signs &
1,4
Symptoms
Immediate aversive (very unpleasant) response to specific patternbased sounds (and sometimes visuals) regardless of decibel
(loudness). This means that trigger sounds can be loud or quiet.
Elicited by other people, animals and inanimate objects. Some
common trigger sounds reported by people with misophonia include:
–
–
–
–
Chewing
Throat clearing
Slurping
Finger tapping
(1) Edelstein et al., 2013
(4) Jastreboff & Jastreboff, 2002
– Foot shuffling
– Keyboard tapping
– Pen clicking

Typical Responses to Triggers
5, 6
■ Can vary from mild to severe
■ Physiological : Muscle tension, headache, stomach issues
■ Emotional: Distress, urge to flee, anger, disgust, rage, panic, anxiety, feelings of
inadequacy
■ Cognitive : Worrying, difficulty focusing, blaming others and/or self
■ Behavioral: Escape, avoidance, or withdrawal from aversive stimuli and situations,
mimicking others, asking others to stop particular sound/action, verbal (possibly
physical) aggression toward self, others, or inanimate objects

What is NOT Misophonia?4
■ Tinnitus: A ringing in one or both ears. Possibly due to injury of the auditory nerve
and/or a continued “phantom perception” of the sound. Often accompanied by
hearing loss
■ Hyperacusis: Aversive responsivity to loud sound, or sounds that are perceived as
loud
■ Phonophobia: Fear of particular sounds, often brought on by hyperacusis
■ All under broader category of decreased sound tolerance and have overlapping
features with misophonia

What is NOT Misophonia? (cont.)1, 5
■ Synesthesia: In synesthesia atypical brain connections cause two unrelated sensory
stimuli to connect (such as a color and a number)
■ Anxiety: While most people with misophonia feel anxiety or anxious feelings related to
the disorder, misophonia and anxiety are not the same
■ Obsessive-compulsive disorder: Although some researchers have suggested that
misophonia be classified under obsessive-compulsive spectrum disorder, there is little
evidence to support this
■ Overlaps and co-occurrences of these disorders with misophonia warrant research,
but it is too early to make generalized statements or base treatments on these ideas

What Does the Research Say?
■ Very few peer reviewed articles (under 25)
■ Out of those, very few are experimental in nature, meaning they rely
mainly on case studies and the experiences of very few people
■ Regardless, there is agreement across the small body of research that:
– Misophonia is real and varies in severity from mild to severe
– Underlying mechanisms are auditory and neurological with behavioral, cognitive,
and emotional responses
– Misophonia should not be classified as any specific type of disorder (i.e.
psychiatric or auditory) but should be researched and conceptualized across
multi-disciplinary fields such as audiology, psychology, neurology, neuroscience,
medicine, nursing, occupational therapy, etc.
■
Across these disciplines it appears that misophonia is best described as a neurophysiological
disorder that has to do with atypical connections between the auditory pathways in the brain and
the pathways in which emotions are processed, particularly fight/flight

Possible Etiology
5,
7,
8,
9
(Causes)
■ No single cause has been determined
■ Most likely related to atypical connectivity between auditory brain areas and the
parts of the brain that process emotion (often referred to as the limbic system)
■ One of the candidate brain areas that is highly likely to be involved is the
amygdala, as it mediates autonomic (involuntary) nervous system arousal and
fight/flight response
■ Other brain areas include the insula and parts of the medial frontal lobe, which
are also known to be involved in emotion processing

Misophonia and the Nervous System
■ One way to think of misophonia is as a neurophysiological disorder
Neurophysiological refers to functioning of the nervous system
■ The nervous system is comprised of the brain and the spine (Central Nervous System,
CNS) and a large network of nerves that allow communication to take place
throughout the body (parts of which make up the Peripheral Nervous System, PNS).
■ These two systems feedback or “communicate” with one another to make possible both
voluntary and involuntary actions, as well as thoughts, and emotions that we observe as
behavior
■ Stimuli from the outside world enters our system through a sensory organ (sound enters
through the ear) and is processed through this very complex system

The Nervous System
12
The Autonomic (Involuntary) Nervous System
– This is the branch of the peripheral nervous system that is responsible for
involuntary physical changes related to the fight or flight response, and it is
divided into two branches (sympathetic system and the parasympathetic)

Responding to Danger3, 10, 11
■ One way to best characterize misophonia is that you are responding to sounds as
though they are dangerous in a part of the brain that is subconscious and does not
involve cognition.
■ Whereas most people would stop responding to novel sounds as though they
were dangerous, people with misophonia appear to continue to do so. This is
called habituation and in the case of auditory stimuli, auditory gating. This is
why it is so difficult to control the response “in the moment” and why it takes so
much work to learn to do so.

How Do We Assess
12,
13
Misophonia?
■
As of now there are several assessment scales available on the internet and being used by
researchers
–
–
–
–
Misophonia Assessment Questionnaire (MAQ)
Misophonia Activation Scale (MAS-1)
The Amsterdam Misophonia Scale (A-MISO-S)
Misophonia Questionnaire (MQ)
■
However, these scales are new and have little to no reliability (consistency within the scale or
over time) or validity (i.e., may not be measuring what they claim to measure)
■
Developing a new scale scientifically is an extensive and timely process
■
Although exciting to see scales being used because this helps confirm that misophonia is real,
because this cannot be tested simply (i.e., with a blood test), people who make tests have to be
really rigorous and sufferers have to be very critical of them. At this stage, scales should be
thought of as indicators not as decisive evaluations

Misophonia Assessment Questionnaire (MAQ)14
■ Created by a seasoned audiologist (Marsha Johnson)
■ Questions ask people to rate how much they are impacted by “sound issues”
■ Scores range from subclinical to extreme
■ Face valid items; easy and brief to administer
■ It is not a measure to diagnosis misophonia, but can be used as a way to indicate the
severity of misophonia symptoms
■ Scientific data are needed to more clearly demonstrate that the measure is both
reliable and valid

Misophonia Activation Scale (MAS-1)15
■ Devised by advocates of the nonprofit group Misophonia UK
■ Questions refer to both physical sensation as well as emotional responses
■ Scale from 0 (a person with misophonia who hears a trigger but experiences no
discomfort) to 10 (“actual use of physical violence on a person or animal, or selfharm”)
■ Although this scale is a work in progress, it has been used by sufferers and
researchers
■ No scientific evidence linking misophonia to physical violence, therefore not
appropriate to conflate them here
■ Scale also does not discriminate misophonia from other disorders (such as
disorders that are known to relate to physical violence)
■ At this early stage of research, we caution against using this scale for diagnostic
purposes until further scientific research is conducted on the scale

The Amsterdam Misophonia
Scale (A-MISO-S)8
■ Developed by 5 psychiatrists/psychologists in order to measure the severity of
misophonia symptoms
■ 6-item scale (with a range of 0–24)
■
–
–
–
–
–
–
Addresses
time an individual is occupied by misophonia
how much misophonia sounds interfere with social and work functioning
individual’s level of anger in response to sounds
level of resistance against impulse to react
how much control the individual has over thoughts and anger
how much time an individual spends avoiding misophonia situations
■ Scores range subclinical misophonic symptoms to extreme
■ Adapted from a measure of obsessive compulsive disorder (OCD)
■ Because misophonia and OCD are not the same disorder, creating a misophonia scale
based on an OCD scale may confound OCD with misophonia; more research is
necessary to ensure this scale is truly measuring misophonia

Misophonia Questionnaire
6
(MQ)
■
Aims to develop scale using preliminary scientific test construction methodology
■
Three part scale that asks questions about symptoms, emotions, and behaviors
■
Scale items drawn from clinicians working in OCD clinic; ideally would draw from less specific
population
■
Study participants largely young, white, and female, ideally would be wider sample
■
Scale appears to be reliable (e.g. consistent when administered over time)
■
Preliminary evidence of validity, as MQ correlated with measure of sensory over-responsivity,
(convergent validity)
■
However, less evidence that scale measures specifically and only what it reports to measure
(discriminant validity)
MQ may measure SOR, not misophonia
■
Study using this scale represents initial scientific effort to create valid scale, however much more
research needs to be conducted before MQ can be used widely by suffers, clinicians, and researchers

How Can We Assess Misophonia in the
Meantime?18, 19
■ Extensive medical interview and physical examination
■ Rule out hearing disorders/symptoms of medical conditions or
medication side-effects
■ Screen for signs of co-occurring mental health or physical
problems
■ Apply multidisciplinary, transdiagnostic approach

What Can I Do if I Have Misophonia?
■ Learn as much as you can
about the disorder from
credible sources
■ Seek treatment from qualified
professionals
■ Learn and implement coping
skills

How Can I Tell Which Sources Are Reliable?
■ It is often difficult to parse out reliable from unreliable
sources in the age of the Internet
■ It helps to look for institutions that are:
– Established, known to be credible, affiliated with advisory
boards that are credible, are positive and supportive
– Important to research sources and their authors, ensure author
has proper training and background to provide accurate
information

Who Can You
20
Trust?
Reliable clinicians:
■
Explain that research is in the beginning stages
■ Do not sell ”overnight cures,” or promise immediate results
■ Do not sell expensive products to “treat misophonia”
■ Are empathic and open-minded
■ Are willing to consult with cross-disciplinary specialists and/or other therapists that are more
knowledgeable about misophonia
■ Will help you develop effective coping skills

Multidisciplinary Team Approach
■ Patients present with misophonia symptoms to a variety of healthcare
professionals
Primary care physicians, pediatricians, neurologists, psychologists,
psychiatrists, other behavioral health professionals
■ Recommended use of multidisciplinary approach and individualized care
plan when working with patients that report impairment in functioning
and significant psychological distress associated with symptoms of
misophonia
■ Note: this may not be easy to find and we are just beginning to formulate
ways to make this possible

About Avoiding Unpleasant Sounds21
■ There is no formula for when to avoid or approach sounds, no right or wrong
■ Avoidance and escape from aversive stimuli is normal
■ Whenever possible, safe, and effective, avoidance/escape from triggering sounds may
be the needed initial response
■ While we cannot always avoid sounds, it is an adaptive coping skill to leave the
presence of a trigger sound when autonomic nervous arousal is too high (and/or
fight/flight is set off)
■ When you do this, your nervous system goes back to baseline, or homeostasis (calm).
Remember people with misophonia are likely to have difficulty with habituation
■ Sometimes after a brief period of homeostasis, one can return to the presence of the

sound in a better physiological state

Why is it That Some Days Triggers are
Worse Than Other Days ?19
■ There are numerous factors that will affect
how difficult coping with a trigger sound will
be. Here are some of those items:
– Physical health and rest
– General mood affects physiological arousal
– Anxious thoughts about a situation raise
physiological arousal
– Recent prior experience with trigger
situations make new trigger situations more
likely as all sensory information is cumulative
(i.e. breaks from overwhelming auditory or
visual stimuli are important to reset the
system)

Why Do Certain People Trigger Me ?
Although research has not identified reliable answers to this question, there
seem to be some reasons that may account for this:
■ There may be acoustic elements of particular sounds that are worse with some people and
not others
■ Even though it may be the actual sound that begins as the problem, or the way the brain
processes the sound, we do make memories associated with the people who we are around a
lot and/or who make particular sounds that bother us
■ If arousal is higher, perhaps due to anxiety within a relationship with a particular person, this
may make one more vulnerable to developing and/or storing in memory triggers with a
certain person
■ However, as these sounds do seem to cluster together (i.e. so many people describe the same
sounds that bother them), it is helpful to think of the sound itself as the trigger and not the
person

Coping Skills10
■ Regulate, Reason, Reassure Coping Skills Program
–
–
–
–
Not a miracle cure but with hard work can help cope
Can be done by adults and/or parents with their children
Highly individualized for people and their families
Very Brief
– Regulate: Use effective strategies to bring nervous system back to homeostasis
-These can be learned and are different for everyone
– Reason: Separate trigger sounds from people, cognitively assess how to handle situation going forward,
– Reassure: Reassure yourself (or your child) that this is not easy and that you are doing a good job.
“Rome wasn’t built in a day.” This is a process and it doesn’t work overnight, and it doesn’t
work all the time. Learn to forgive yourself and others
